Lesson 3

Longitudes de lado específicas

Lesson Purpose

The purpose of this lesson is for students to recognize and draw shapes that have sides with a given length. Students also revisit and practice measuring lengths.

Lesson Narrative

In a previous unit, students measured and compared the length of the sides of triangles and rectangles with rulers. In previous lessons, students recognized and drew shapes on dot paper based on a given number of sides and corners. In this lesson, students measure sides with rulers to find shapes with specific attributes. Students use their rulers to draw shapes with given side lengths (MP6).
