About this unit

"This module begins the year by building on students’ fluency with addition and their knowledge of arrays. In Topic A, students initially use repeated addition to find the total from a number of equal groups (2.OA.4). As students notice patterns, they let go of longer addition sentences in favor of more efficient multiplication facts (3.OA.1). Lessons in Topic A move students’ Grade 2 work with arrays and repeated addition a step further by developing skip-counting rows as a strategy for multiplication. Arrays become a cornerstone of the module. Students use the language of multiplication as they understand what factors are and differentiate between the size of groups and the number of groups within a given context. In this module, the factors 2 , 3 , 4 , 5 , and 10 provide an entry point for moving into more difficult factors in later modules." Eureka Math/EngageNY (c) 2015 GreatMinds.org
