Lesson 7

Build with Straws

Lesson Purpose

The purpose of this lesson is for students to build shapes from components.

Lesson Narrative

In a previous lesson, students compared the length of rectangles that were lined up. In this lesson, students work with straws to build shapes. Students initially compare the length of the straws and then use the straws to build shapes. If straws are not available, other materials may be used as long as there are at least 4 different lengths of the material.
