# Lesson 10

¿Hay suficientes?

### Lesson Purpose

The purpose of this lesson is for students to develop and practice one-to-one correspondence in the context of answering "are there enough" questions.

### Lesson Narrative

While some students might count the number of objects and compare that number to the number of students, the focus of the activity is on matching one object to each person to see if there are enough.

Each of the lessons in this section begins with a How Many Do You See routine to build on the subitizing work in a previous section. Students extend the Act It Out routine with a new story.

Throughout the section, observe students for the look-fors on the Unit 1, Sections A-D Checkpoint.
