# Lesson 12

### Lesson Purpose

The purpose of this lesson is for students to connect quantities to written and spoken numbers.

### Lesson Narrative

In previous sections, students connected quantities to spoken number words. In this lesson, students connect groups of objects to written and spoken numbers. A reference sheet is provided for students who do not yet recognize all of the written numbers. Students can determine how many dots there are to figure out which number it is.
