This Fluency Activity is a part of the Lesson 25, Unit 2, Grade 1. This activity builds fluency with the make ten addition strategy and reinforces the meaning of the equal sign, which prepares students for today's lesson. Students find different numbers that make the equation true and check their answers with a partner. If necessary, students can use counters in addition to drawings that they can make on their personal white boards. During the last minute, ask for volunteers to share the equations they found.
