# Lesson 16

Representemos nuestras colecciones

### Lesson Purpose

The purpose of this lesson is for students to count collections of objects. The focus is on students representing how they counted.

### Lesson Narrative

In the Questions About Us routine, students use 5-frames to determine how many students are at school today. Students then count objects in different collections in a way that makes sense to them and represent their collections. The second activity is an optional activity that provides support in keeping track of which objects have been counted.
