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.
