Subtracting With and Without Regrouping Introduction
Students will be introduced to the concepts of subtraction both with and without regrouping. Several strategies, including base 10 blocks, picture models, number lines and the traditional algorithm are use to drive instruction and encourage participation and collaboration. Lesson rigor and complexity increases as students are challenged through a series of questions all including models. As students progress through examples the complexity and rigor increases. Scaffolds and animations provide di
