Lesson 12

Restémosle a un número del 11 al 19

Lesson Purpose

The purpose of this lesson is for students to add and subtract within 20 without composing or decomposing a ten.

Lesson Narrative

In previous lessons, students learned the 1\(0 + n\) structure of teen numbers and considered the relationship between addition and subtraction. The purpose of this lesson is for students to use their understanding of the structure of teen numbers to add and subtract from a teen number, without composing or decomposing a ten (MP7). Students use methods they used in a previous section such as counting on, taking away, or relating addition and subtraction.
