Lesson 12

Hagamos imágenes de puntos

Lesson Purpose

The purpose of this lesson is for students to develop fluency with adding and subtracting within 5 as they identify compositions and decompositions of numbers to 5.

Lesson Narrative

Students participate in a How Many Do You See routine and then create their own dot images to use in a version of the routine in small groups. Understanding that numbers can be composed and decomposed in multiple ways is an important step towards adding and subtracting fluently within 5. When they make dot images and share with their partners students practice, through visualization (MP7), fluency for arithmetic facts within 5.

If students need additional support with the concepts in this lesson, refer back to Unit 5, Section A in the curriculum materials.

Teacher Reflection Questions

As students worked with their partners and small groups today, whose ideas were heard, valued, and accepted? How can you adjust the group structure tomorrow to ensure each student’s ideas are part of the collective learning?
