Make It Equal: Subtraction Expressions

This Fluency Activity is a part of the Lesson 2, Unit 5, Grade 1. This activity builds fluency with subtraction within 10 and promotes an understanding of equality. Assign students partners of similar skill or ability level. Students arrange numeral cards from 0 to 10, including the extra 5. Place the "=" card between the partners. Write four numbers on the board (e.g., 9, 10, 2, 1). Partners take the numeral cards that match the numbers written to make two equivalent subtraction expressions (e.g., 10 - 9 = 2 - 1).
