Open Up Resources 75 min(s)Support for English Language Learners

Understand and explain that one can find the area of any polygon by decomposing and rearranging it into rectangles and triangles. Let's investigate polygons and their areas. Learning targets: students can reason about the area of any polygon by decomposing and rearranging it, and by using what they know about rectangles and triangles. If doing the optional Pinwheel activity, prepare one copy of the blackline master for every group of 4 students.
