# Lesson 5

Center Day 1 (optional)

### Lesson Purpose

The purpose of this lesson is for students to practice describing, naming, and drawing triangles, quadrilaterals, and hexagons based on their defining attributes.

### Lesson Narrative

This lesson is optional because it is an opportunity for extra practice that not all classes may need. In Activity 1, students learn stage 3 of the Which One center, which was first introduced in Kindergarten. In this new stage, called Grade 2 Shapes, students work with triangles, quadrilaterals and hexagons as they ask their partner yes or no questions to figure out what shape they chose. In Activity 2, students learn stage 2 of the Can You Draw It? center, which was first introduced in Grade 1. In this new stage, also called Grade 2 Shapes, students continue to work with triangles, quadrilaterals and hexagons as they describe and draw two-dimensional shapes.
