 # Decomposing Numbers 0-10

Kindergarten • Half Day Lesson Plan
\$4

## Lesson Plan Description

This fully scripted Kindergarten half day lesson plan is broken down into 2 separate segments (30-60 minutes each). The lessons address Operations and Algebraic Thinking: Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1) (K.OA.3). The lessons include: an introduction to what decomposing a number means, interactive demonstrations of decomposing numbers, using number bonds to show decomposition of a number, using manipulatives to show decomposition of a number, an  exit slip as an optional assessment component for students to show understanding of decomposition of numbers, and finally a game for students to review and practice decomposing numbers 0-10.

• Segment 1: Students will decompose numbers less than or equal to 10. Students will also learn that numbers can be represented in a different way.
• Segment 2: Playing a game called, “Finger Cubes,” students will practice decomposing numbers less than or equal to 10. Students will also represent numbers as an equation.

These lessons can be taught over the span of a half day or you can use the lessons independently, broken up over several days.
