Module 5 Understanding Division

Division tends to be the toughest of the four operations for students, so how can you create a deeper understanding? In this module you will explore various visual models for division as well as the "how and why" for long division and repeated subtraction. You will use centimeter strips and blocks to clarify the long division algorithm (partition) and repeated subtraction algorithm. You will also discuss why you cannot divide by zero. Coming out of this section you will be prepared to answer the wide variety of student questions that arise when you teach them division.
