This Fluency Activity is a part of the Lesson 26, Unit 1, Grade 1. This activity connects fluency work of addition and subtraction within 10 with the number path as a tool for modeling addition and subtraction. Students make a number path by ordering their 5-group cards from 0 to 10. Instruct the students to place their counters on 0, and give a series of directions. "Hop forward 2. Where are you?"
