Lesson 15

Explain How You Counted

Lesson Purpose

The purpose of this lesson is for students to count collections of objects. The focus is for students to show and explain how they counted to a partner. 

Lesson Narrative

In the Questions About Us routine, students brainstorm different ways to represent how many students are at school today. Students then count objects in different collections in a way that makes sense to them and share how they counted the collection with a partner. The second activity is an optional activity that provides support in matching each object with one number.
