Curriculum for Grade 3

Students' strong foundation of math skills facilitates the shift to multiplication and division, moving from concrete procedures toward abstract thinking and automaticity.

MODULE 1. Properties of Multiplication and Division and Solving Problems with Units of 2-5 and 10

Topic A: Multiplication and the Meaning of the Factors

Students build upon their knowledge of addition to identify factors (how many groups, how many objects in each group) and to compose and solve simple multiplication equations. They work with groups of 2-5 identical objects, beginning with models of identical concrete objects, such as bunches of bananas and fingers on a hand. As students progress, they work with more abstract objects (identical beads) and objects in an array.
