Unit 8, Lesson 13
Dominoes to 5
Kindergarten
Preparation
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
In a previous lesson, students created their own dot images and identified different compositions and decompositions of numbers to 5. In this lesson, students work with dominoes. Students sort dominoes by total, which encourages them to recognize different compositions and decompositions of numbers to 5 and think about both the parts and the total at the same time. Students also compare the numbers of dots on the dominoes.
If students need additional support with the concepts in this lesson, refer back to Unit 5, Section B in the curriculum materials.
