Session presented at the Michigan Council of Teachers of Mathematics annual conference in Traverse City, MI.
In this hands-on session, we introduced several sample tasks that included use of computer applets to strengthen understanding of length and area concepts. Many students struggle with length and area, using only pen and paper or physical manipulatives. In this session, we provided materials to support their learning (that will be available for use during and after the session).
We asked participants to use their devices to work through one sample lesson (Area of Rectangular Regions) including Launch / Explore / Summarize components. We gave participants two sample lessons that they could in their classrooms, along with applets designed and created by Strengthening Tomorrow’s Education in Measurement project.
- Lower elementary – Area of Rectangular Regions which used applets from STEM:
- Launch: https://www.msu.edu/~stemproj/flash/basic_counting/area_rec_tile.html
- What are different ways we can find area of rectangular regions?
- What are different units we can use to find the area?
- Why do we prefer square units over rectangular units?
- What is the relationship between unit and area?
- Upper elementary – Area of Parallelograms
