EngageNY4 min(s)

This Fluency Activity is a part of the Lesson 21, Unit 2, Grade 3. This activity reviews rounding to estimate differences from Lesson 20. Some learners may be more successful estimating and subtracting if allowed support (without stigma), such as base ten blocks, a place value chart, or a calculator. Maintain high expectations of student achievement, and set realistic personalized goals that they are steadily guided to attain.
