Unit 1, Lesson 6# Scaling and Area

Open Up Resources 40 min(s)

Let's build scaled shapes and investigate their areas. Learning targets: students can describe how the area of a scaled copy is related to the area of the original figure and the scale factor that was used. Required Materials: pattern blocks pre-printed slips, cut from copies of the blackline master geometry toolkits. Prepare to distribute the pattern blocks, at least 16 blue rhombuses, 16 green triangles, 10 red trapezoids, and 7 yellow hexagons per group of 3-4 students. Copy and cut up the Area of Scaled Parallelograms and Triangles blackline master so each group of 2 students can get 1 of the 2 shapes.
