Lesson objective: Apply using a ten frame to solve problems.

This lesson provides an opportunity for students to apply their knowledge and understanding of counting to a mathematical situation. Students are asked to sort familiar objects into a ten frame in order to answer the question how many objects are found in the box.

Key Concept students will use:

- We can count to answer how many objects are arranged in a line or a rectangular array
**.**

Skills students will use:

- Writing numbers within ten (Grade K, Unit 2)

Students engage in Mathematical Practice 1 (Make sense of problems and persevere in solving them) as they arrange objects in ten frames to solve problems.

**Key vocabulary: **

- arrange
- count
- objects
- ten frame
