### Description

This unit is the fourteenth unit of a first grade MASTER math curriculum. It is built around the belief that students need to be exposed to math in a variety of ways. This unit focuses on adding and subtracting 2 digit numbers together without regrouping. Master Math can be taught in many ways but I will provide the tools to make it a rotation based learning process. Each lesson begins with a whole group mini lesson provided in a SMART notebook version or a pdf file. Then students begin to rotate (much like centers). MASTER stands for Manipulatives, Apply Skills, Small Group, Technology, Enrichment, and Review. There are activities provided for each component listed, lesson plans, assessments, SMART notebook files, and a fun culminating craft. There is some regrouping in the Enrichment piece of this file. Included you will receive:
