Lesson Plan Description
This fully scripted Kindergarten bundle is broken down into 2 separate segments (30-60 minutes each). The lessons address Operations and Algebraic Thinking: For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation (K.OA.4). These lessons include: a review of counting to 10, separating 10 objects into 2 distinct groups, illustrating these distinct groups using an addition equation, and using ten frames to visually show the decomposition of a number. This lesson includes an exit slip as an optional assessment component and a game called, “Snap It” to review and practice decomposing numbers less than or equal to 10.
- Segment 1: Students will separate 10 objects into 2 groups in different ways. Then they will write number sentences adding 2 numbers to equal 10. Students will also use a ten frame to decompose the number 10.
- Segment 2: Students will further practice these skills by playing a game called “Snap It – Decomposing the number 10”
These lessons can be taught over the span of a half day or you can use the lessons independently, broken up over several days.
