Engage your students with this activity where they are required to build rectangles, squares and triangles out of polystrips and then calculate area and perimeter of each figure. This activity is a hands on approach which appeals to the students. I usually have them work in pairs.
Materials necessary: long and short polystrips (4 of each per group), small brass fasteners, a ruler
This activity allows me to reinforce:
1. Key vocabulary (vertices, sides, polygon, area, perimeter)
2. Measurement to the nearest inch OR 1/2 inch - great for differentiation
3. Geometry formulas - square, rectangle and triangle
4. Basic math skills (I allow students to check their answers with a calculator but they have to show all work in the space provided)
