# Lesson 7

Formemos números con 10 y algunos más (parte 1)

### Lesson Purpose

The purpose of this lesson is for students to compose numbers using 10 ones and some more ones.

### Lesson Narrative

Students write a number to represent a quantity greater than 10 for the first time. Students use full 10-frames and some more to identify and create numbers 11–19. Students may count all of the dots or counters to determine the teen number, or they may count on from 10. Counting on to determine the total is not an expectation in kindergarten.
