EngageNY10 min(s)

This Problem Set is a part of the Lesson 15, Unit 5, Grade 2. In this lesson, students continue to build their conceptual understanding of subtracting numbers within 1,000. They continue to move from concrete to pictorial representation, as they use chip models to represent decompositions while simultaneously recording these changes in vertical form. This helps them to relate the pictorial representation to the standing vertical algorithm.
