Lesson 16

The purpose of this lesson is for students to apply their understanding of geometric figures and measurements to draw, describe, and identify two-dimensional figures.

This lesson is optional because it does not address any new mathematical content standards. This lesson does provide students with an opportunity to apply precursor skills of mathematical modeling.

In the first activity, students practice using the geometric vocabulary they acquired during the unit to describe changes they notice in a given figure. In the second activity, students first draw a two-dimensional figure and then describe it to a partner without showing it to them. The partner attempts to draw the figure based solely on the description. Students have an opportunity to compare the original and drawn figure.

• Create a set of cards from the blackline master for each group of 2 students.

Which students had opportunities to share their diagrams and thinking during the whole-class discussion? How did you select these students?
