More and Less: Multiples of 10

This Fluency Activity is a part of the Lesson 3, Unit 4, Grade 2. In this lesson, students use relationships between the numbers to develop a variety of simplifying strategies to add and subtract multiples of 10, with adding the complexity of some ones, so that the ones digit is close to a multiple of 10. Students review Lesson 2 by adding and subtracting multiples of 10 fluently.
