Week 4: Reflection (Review / Cross Class Math Groups)

This week, I was in the math classroom on Tuesday, Thursday, and Friday. On Wednesday, the students took their first math test of the year.
On Tuesday, we reviewed. It was a bit chaotic, but I took some groups of students to review rounding, addition, and subtraction – it ended up being three groups or maybe four that I worked with. I gave students a few exercises and then asked if they wanted to challenge each other, so they wrote numbers to round or add. Each had a turn and seemed to enjoy the power / responsibility.
On Thursday, I led the hands-on game during centers. Many students had struggled with translating between standard, expanded, and verbal forms of numbers. The teacher, made a sorting game for them with three forms for each number. I found that the game worked best if three or four students laid out all of the cards face up and just went at it – trying to find as many matches as they could. They were pretty good about sharing and helping each other as well as being competitive. Then after a few rounds, they started dragging, so I asked if they wanted to make it into a “Memory” game and that upped the challenge a bit but seemed still fun for them. (Starting out in “memory” mode did not work well!)
On Friday, the fourth grade classes did a crossclass remediation. 22 students from two other classes came to my teacher’s classroom, and all of her students left for other classrooms. We worked on place value. I led a dice game where partners or triples would roll three ten-sided dice twice and try to write a number that was closest to a goal. The goals were written on their “score sheets” as: “closest to 0,” “closest to 1,000,000,” “closest to 500,000,” “closest to 250,000, and “closest to 750,000.” The game sort of worked but because I had 11 students at a time and because I don’t know them, it was fairly chaotic. (see more description of this game: Task: Place Value Dice Game)
Looking back, I should have shared clear expectations by asking students: “What should I hear? What should I see?” The teacher has a poster about “hands-on expectations” so I could have gone over that. But, the first group was way too wild. I tried to compensate with the second group by telling them I would take the dice away if they were throwing or playing with them. That led to about five minutes of answering questions like “What if I shake the dice and one falls out?” “what if I roll the dice and one rolls too far and falls on the floor?” Poor kids!

Task: Place Value Dice Game

This task (game) was given to me by my teacher: I did not plan it, but only implemented it.

Task Description

The goal of the task was for students to think about place value and “periods” (in the number 365, 728, “365” is a period in the thousands place and “728” is a period in the ones place. Then the students can read each period the same, but appending the appropriate period name: “Three hundred sixty-five thousand, seven hundred twenty-eight (ones).”)

Students were given three ten-sided dice and a worksheet for record-keeping.


Students would roll the set of three dice twice, writing down the three-digit number using the place value on each die.

Then they would decide which period would make more sense to be first, depending on the goal from the worksheet.

For example, if they rolled 365 with one roll and then 728 with a second roll, they could choose to have the number “365,728” or “728,365”.

The worksheet had about 12 “find a number closest to…” goals available:

  • 3 goals were: “Closest to zero”
  • 3 goals were: “Closest to 1,000,000”
  • 2 goals were: “Closest to 750,000”
  • 2 goals were: “Closest to 500,000”
  • 2 goals were: “Closest to 250,000”

Students were in pairs and whoever was closest to a number “won” that round and got a point.

Reflection on Task and Implementation:

We started out on the carpet at the front of the room, but some students in the first group asked to move to desks to make it easier to roll the dice and record responses. I write more about the struggle I faced for my own communication of expectations in Week 4: Reflection (Review / Cross Class Math Groups).

In each group, some pairs of students were very focused on rolling the dice and finding the closest number. But at least one pair in each group struggled to stay focused – either one student would not take turns with the dice or would roll them wildly multiple times. I wondered if one solution would be that each student had their own set of dice and they could work together or individually. I also wondered if it would have been different if I had known the students and been able to shuffle partnerships to be more balanced.

In the moment, I decided that I had been unclear with my expectations with the first group, assuming that they would know what I expected regarding use of resources. For the second group, then, I briefly told them my expectations, ending with “if the dice don’t stay on the desks, I will take them away and you will have to complete a different activity.” At that point, hands went up and students asked about boundary cases: e.g., “if I roll the dice, and one falls out accidentally…”

For the partners that were on task, the game seemed fairly straightforward and even easy. I don’t remember if there were any “Choose your own goal” slots on the sheet, but I think it would have been interesting for students if they could choose their own goal and try to achieve it.


Task: Math is Everywhere… in Logan

Planning Task

I adapted this task based on pages 120-121 in Van de Walle.1
Math is everywhere. People use it all the time in the world and at work and at home. Part of math is just being curious and asking questions and looking for patterns that help you make sense of the world. Yesterday, while you were at school, I took some pictures of different places where I think people do math.

  1. Which of these do you recognize?
    1. Willow Park Playground
    2. Willow Park Wildlife Center
    3. Logan Aquatic Center
    4. Logan Library – Books
    5. Logan Library – Programs
  2. Which have you visited?
  3. Can you think of any other places where you do math that isn’t your house and isn’t school?
  4. What are some other places where you think you might do math?

Decide as a group: Which picture / place do you want to use for math today?

  • What math could you do here – I mean, what math questions could you ask?
  • I asked myself some math questions and chose one. Before you try to answer it, I want you to Analyze the question and Make Sense of it, so I’m going to ask you some questions.
    • What does analyze mean?
    • What is happening in the question?
    • What will the answer tell us?
    • Why is it interesting to know? Or who could the answer help?
    • Do you think the answer will be a big number or a small number?
    • Can you estimate the answer?


Willow Park Playground:

When you plan a playground, what do you have to think about?
wp_20160922_14_55_00_proThe Sway Fun glider costs $34,628 and a Swingset costs $3,298. Which costs more? How much more? What does that tell the planning group?

Willow Park Wildlife Center

The Wildlife Learning Center needs to know how many kids will go to Story Time each month.
wp_20160922_15_01_02_pro-2In 2008, there were 943 kids that visited Story Time the whole year. In 2013, there were 497 kids that visited. Which year did more kids visit? How many more? What does that tell the Center?

Logan Aquatic Center

The Aquatic Center needs to know if it’s using too much water.

wp_20160922_15_10_17_proThere’s a park in Draper, Utah called Cowabunga Bay that uses 250,000 gallons. Logan Aquatic Center uses 800,000 gallons. Seven Peak Water Park uses 34,746,096 gallons2 . Which uses the most? How much more? What does that tell the Aquatic Center?

Logan Library – Books

The Logan Library tries to get more books every year so more children can use them.

wp_20160922_15_24_24_pro In 2011, kids checked out 633,330 children’s books. In 2015, kids checked out 434,815 children’s books. Which year did kids check out more books? How many more? What does that tell the library?

Logan Library – Programs

The Logan Library has children’s programs and want more kids to use them. wp_20160922_15_24_08_proIn 2011, there were 2015 kids that came to programs. And in 2015, there were 11,171. Which year did more kids come? How many more? What does that tell the library?

Reflection on Task and Implementation

My first goal was to follow the “Problem Analysis” from Van de Walle on pp. 120-121. The idea is to support students in making sense of the problem and the answer – so not really very different than what you showed them which was awesome! So I wanted to go through:
  • What is happening in the question?
  • What will the answer tell us?
  • Why is it interesting to know? Or who could the answer help?
  • Do you think the answer will be a big number or a small number?
  • Can you estimate the answer?
My second goal (that I hoped would support the first!) was to support the “asking math questions” idea by bringing in the pictures from around Logan – mostly Willow Park and Logan Library. I had others but I talked myself down from preparing for so many problems and thought so many pictures would really be distracting. Part of the goal here is to support students use of their “funds of knowledge” which includes what they know from school and what they know from home and the other things that they do because research has shown that students compartmentalize and so don’t bring in their problem-solving skills, sense-making, or intuition, etc. that they might use outside of school.
This is what really happened…
The reality – I thought I could have kept them on track and moved faster, but I was pleased to here all of their ideas and enthusiasm.  What I actually did was:
  1. Math is everywhere. The goal today is to think about math outside of the class and outside of your homework. Part of math is just being curious and asking math questions about things you notice or wonder about. Where are some place you think you could ask math questions?
    1. I made sure each person told me at least one, although some repeated. Here are some of their responses: stores, library, video games, gummy bear factory (!?!), cookie factory, gas station, the world (how many people are there? how many gallons of water are in the ocean?), Fredrico’s Pizza, Tony’s Pizzeria, Macey’s, Tony’s Grove, LegoLand (how many Legos are in a big creation?), Wal-Mart, Bear Lake, Salt Lake, a road trip, Oregon.
  2. Yesterday, while you were at school, I tried to guess where you fourth-graders might ask math questions when you aren’t in school. So I took pictures that I’m going to show you and I wonder if you have ever seen these places or been to them? (I passed out the pictures and they had no problem recognizing each – and pointed out that they had a field trip last year at the Wildlife Learning Center by Willow Park Zoo.  I think everyone had been to every place, except I think Isaac said he’s from Smithfield so doesn’t go the Logan Library.
  3. As a group, choose which place we will ask our math questions about today. (They were reasonably quick to do this – every group wanted to talk about the Aquatic Center and the Logan Library – but only in only one group did Library win. I told them we would do the library if we had time.)
  4. What are some math questions that you wonder about?
    1. Logan Aquatic Center: How many people go there? (on Wednesday, in a week, in the summer, in the winter, between 2:30 and 3:30); How many people go on Wednesday compared to Friday? or go there vs. stay home? How many workers are there? How many lifeguards? How many lifeguards are there each week? How many people have been hurt on the slides? How many people have broken a leg on the slides? How many people have swallowed a gallon of water? How long is a slide? How long is a curly slide compared to a straight slide? How deep is the deepest pool? How tall is the tallest slide? How much water is in one pool? How many gallons are in a pool? How much does visiting cost? How much would lunch cost?
    2. Logan Library: What is the number of books there? How many at each grade level? How many magazines are there? How many words on a page of a book? How many videos on a YouTube page? (or a YouTube search?) What street is it on? How many people are there?
  5. Estimation: 
    1. Logan Aquatic Center: The question I chose to ask was: How many gallons of water are in all of the pools and slides? So, I found out how many gallons. What do you think the answer is? (I passed out markers and erasers here, and had them write down what they thought. That was interesting – I should have been prepared to write those answers down, but I didn’t. The answer according to the LAC website is 800,000 gallons. Maybe 4 students guessed at the magnitude – 123,000 or 250,000.  Several students guessed a two-digit number: 32, or between 20-30 gallons.  Most students assumed it was a huge number and so wrote something like 999,999,999,999,999,999 or 2,000,000,000,000,000,000,000… They all seemed surprised by 800,000.)
    2. Logan Library: The question I chose to ask was: How many children’s books are checked out in a year? So, I found out how many books. What do you think the answer is? (Two students wrote numbers in the hundred thousand range – these really varied. The answer was 434,815 books in 2015. Time was up or I would have compared the books in 2011).
  6. Subtraction question: 
    1. Logan Aquatic Center: I wanted to know how Logan Aquatic Center compared to other water parks. So I found two others: Cowabunga Bay (in Draper) and Seven Peaks (in Provo). Have any of you gone to those? (Some had – if they had, I made them guess if they thought it had more water or less than LAC.)  Cowabunga Bay uses 250,000 gallons and Seven Peaks uses 34,746,096 gallons2 . Write those numbers down. (Okay – that was my fault! Most struggled to write the 34 million down – but a few were okay. I know that’s bigger than they’ve practiced. By the time we had any two numbers down, time was up! That was okay!)
So – we didn’t really analyze any because of the other parts, but I felt like it was still productive even though we never actually subtracted. I really liked that they chose a place – but I think that took more time than made it useful. I think if I did this again, I would just bring one picture or I would have partners choose one and they would work on different problems as partners.

2  Note: I later realized that the difference in the amount of water is due to the difference in online resources that I used. For Seven Peaks, I found a document describing water usage in Salt Lake City – the 34 million number is probably per year, not its capacity!

Week 3: Reflection

Most of my thinking this week focused on the task I planned for Friday, Task: Math is Everywhere… in Logan.  One thing that I learned from that is that students had many ideas about locations where math can happen and also they had many questions that could be answered by math (e.g., how much water is in the ocean?, how many words are in a book?).

I wonder if a teacher could have a “comment box” for math questions or contexts that students would enjoy? Would that overlap too much with science or social studies? Or would it be too disruptive? It would be important to spend a little more time with some students who might not have connected school math to outside-world-math?

I’m thinking this way because when I teach Elementary Math Methods courses, I ask future teachers to get to know their students and their students neighborhoods in order to bring questions and high-level tasks into the math classroom that allow students to access their cultural funds of knowledge. I think those types of teacher-developed tasks are important. At the same time, I wonder how students can be encouraged to bring their own tasks in?  For older students, Tonya mentioned to potential for students to bring cameras home or bring cameras from home, to take pictures from their daily life that seem mathematical or inspire mathematical ideas or questions.

Week 2: Class Management and First Task

Observation Focus: Class Management

I saw the teacher use many interesting class management strategies throughout the week. The desks are set up in one region of the classroom in the following arrangement:


Student Responsibilities: The teacher expects the students to contribute to the organization of the class. For example, they have timed multiplication or division tests each day. The teacher hands out the answer keys and red pens while the students are working. Students exchange sheets and check each other’s.

Clear Instructions: The teacher gives all students opportunities to contribute by giving tasks to members of each table (made of four desks). For example, after the timings, and after students have had one minute to check each other’s timings, she might say, “Friends closest to the door, please gather the red pens and put them away. Friends closest to my desk, please gather the answer keys and put them away. Friends closest to the flag, please gather the timings and put them in the second math bin. Friends closest to the window, please get markers and erasers for everyone in your group.”

Clear Expectations: After giving clear (but brief) instructions, the teacher also gives clear (but brief) expectations – every time. For example, “While you do this, voices should be off and you should return quickly to your seat. You have 30 seconds.” She uses a variety of expectation words for voices, such as: “Remember, ‘spy talk’ only.” “Boards flat, hands clasped, bodies toward me, eyes on the board.” “Pockets on seats.” “I should hear whispering only.”  She also has posters listing expectations for math centers.

Transitions: The teacher gives clear instructions and expectations before students begin to move, and counts down “Let’s have seats in 10, 9, 8, …” She also uses a variety of phrases to bring students back to attention – for each phrase, she begins and the students respond: [“Focus, focus.” / “Everybody focus.”] [“To infinity!” “And beyond!”] [“One, two, three, eyes on me.” / “One, two, eyes on you.”]

Ensuring Students’ Engagement: The teacher consistently uses many different strategies for ensuring students are engaged and feel like they are part of the work.

She sometimes draws names from a cup; sometimes calls on students; sometimes has students whisper to their elbow partners; sometimes has students whisper in her ear. In the whole-class brief lessons, she often uses manipulative and brings volunteers up to hold them or use the SmartBoard.

She consistently gives wait time, asking students to indicate when they are ready in a variety of ways: “Thumbs up when you think of an answer.” “Share with your elbow partner – let’s have right partner share first.””Finger on your nose when you are ready to share.” “Finger on your ear…” “Silent unicorn…” “Silent mustache…” etc.

Experience Focus: Planning and Implementing a Task

I adapted a task on pages 169-170 of Van de Walle1 to be a 10-15 minute teacher center. I saw that students had good strategies and mostly were engaged.

Two students particularly would not try the task. I asked the teacher about strategies to help them try, and she explained they were both somewhat shy so I might need to let them get used to me. She also explained that one student had good days and bad days, and so it wasn’t always easy to keep her engaged.


I noticed that when I interacted with the students, I spent too much time redirecting their attention to the task. Some students may need to warm up, but I need to practice my teacher moves and group management skills when I interact with the students. Especially when it comes to expectations about using the materials or finding an answer.

I will remind students of expectations with resources briefly before beginning an activity. I will also give more attention to consequences so that students can see the boundaries. I will continue to encourage students to explain their thinking and to look for other strategies.

Task: Ordering Whole Numbers

Planning Task

This week the students were reviewing in chapter 1 of Go Math!. For one day, they focused on “1.3: Compare and Order Numbers.”

I adapted the “Expanded Lesson: Close, Far, and in Between” on pages 169-170 of Van de Walle1 to be a 10-15 minute teacher center.

On individual notecards, I wrote three numbers: 27, 83, and 62. On separate notecards, I wrote the questions:

  1. Order the numbers from smallest to largest. How can you prove it?
  2. Which two numbers are closest to each other? How can you prove it?
  3. Think about three other numbers: 50, 55, and 73. Which of the first three numbers is closest to each of these?

I similarly wrote three larger numbers – 219, 457, and 364 – each on an individual notecard. I wrote similar questions to those above.

As instructions, before I showed the students the first question or the first set of numbers, I told them: You will need to explain why your answers are correct. Use math tools to explain: words, numbers, a number line, pictures, diagrams – whatever makes sense to you.

I planned to ask them questions such as:

  1. Ask one student: What did you decide to do? How do you know? Can you prove it?
  2. Ask other students: Do you understand that strategy? What questions do you have? Who used the same strategy? Who used a different strategy?
  3. After a couple of strategies: Which strategy is most efficient (fastest)? Which strategy is most valid (correct)?

Planning Reflection

Before implementing the task, I wrote a plan for noticing and reflection, based on recommendations in the Van de Walle lesson.

  • Noticing Strategies (e.g., counting by ones, fives, or tens; subtraction; visuals like number line, benchmark, other)
  • Noticing whether students could think of only one strategy or more

Reflection on Task and Implementation

I led the center as one of four centers that students visited. Each group included 4-6 students. I felt generally that the task went well, but we did not have enough time to get past the first group of numbers.

Strategies for “Order the three numbers”: To order numbers, students used a few different strategies.

  • Place value: Most students used place value (we had just gone over using place value to compare numbers in the first part of the math lesson). I felt that I saw some students who used place value procedurally (i.e., simply compared the first digit of each number and could only explain “6 is more than 2 so this number must be bigger”) and others who used it conceptually (i.e., compared the first digit of each number and explained something similar to “6 tens is more than 2 tens”).
  • Counting: Many students counted or used counting as a justification: “I know because I count to 27 first and then 62 and then 83.”
  • Diagram: One student drew the numbers with hash marks between them representing tens: 27”’62’83 (he counted: 27, 30, 40, 50, 62, 70, 83). This strategy was similar to the place value strategy, but a different way to visually show the place values.
  • Number Line: One student drew a number line using time as a measure to determine length between the numbers. She was only able to compare 27 and 62, but explained she knew 62 was larger than 27 because of the number line. This strategy was a visual representation of her counting, because she drew the line with a tiny push forward for each number as she counted from 1 to 27 and then from 27 to 62.

Strategies for “Which of the first three numbers is closest to each of the second set?”: To order the second set of numbers, students used a few different strategies.

  • Order and Connect: Several students ordered the second set of numbers (50, 55, 73) and then connected them directly to the ordering of the first set (27, 62, 83). So, they said 27 was closest to 50, 62 to 55, and 83 to 73. This strategy almost worked except that 50 is closest to 62 instead of 27.
  • Subtraction: Some students subtracted and found that 50 and 55 are both closest to 62. (only 3 or 4 of the 22 students weren’t “tricked”)

Group Management: I noticed that some groups and some students were more engaged than others. I asked the teacher the next day:

  • What are some strategies for keeping students on task and using tools appropriately? (some students were drawing pictures instead of comparing numbers or listening to other students’ strategies)
  • What are some strategies for supporting students in thinking about more than one strategy and trying at least one strategy?
    • I thought one strategy could be to choose the tools carefully and “force” different strategies by giving different students different tools.

Week 1: Welcome to the Classroom

After talking to a mathematics specialist in local elementary schools, I was able to connect with and meet a local fourth-grade teacher and then meet her class within the first couple of weeks of the school year.

The school uses Houghton Mifflin Harcourt’s GO Math!® curriculum1 in conjunction with ThinkCentral2 and ExploreLearning Reflex® 3. The fourth-grade teachers collaboratively plan by meeting one hour during school each week. They discuss scheduling, lessons, assessments, and assessment results.

The teacher I am observing structures her 1.5 hour mathematics lesson as follows:

  1. Students return from lunch at noon, and find their appropriate timing sheet for multiplication or division. (The teacher has a record on the wall showing which timings they have passed off.)
  2. By 12:05, most students have returned from lunch and are ready for the timing. The teacher twists the face of the timer hanging on the whiteboard at the front of the class for 2 minutes. As students complete the timing, they pull a book from their desks and begin to read.
  3. As students work, she passes out red pens and laminated sheets with the answers to all multiplication or division timings on each sheet. Students exchange timings with an elbow partner, check them, and mark them with a check or an “x” to indicate if their classmate has passed or not.
  4. The teacher instructs students to return the materials. For example, “Friends nearest the window, return the red pens. Friends closest to my desk, return the score sheets. Friends closest to the door, collect the timings and put in the math basket – third one down.” She sets the timer for another minute and students scatter.
  5. After timings, a brief 20-minute or so lesson on the day’s topic
  6. After the lesson, students break into four groups for centers: Tech Time (Reflect Math), Hands-On (game on the carpet), Teacher Time, and Seat Time. Each center lasts approximately 15 minutes and the math lesson ends at 1:30.
