**Instructions for Use**

**Ten Frame** allows students to practice counting, using 10 as a benchmark. Once they have answered the question “How many are there?” or “How many are empty?” get the students to write an addition sentence where the sum is 10. For example if the Ten Frame shows 7 counters, a student would write 7 + 3 = 10.

Look at the Ten Frame and answer the question at the top of the screen. Then write an addition sentence that describes the Ten Frame model.
