Multiplication and division
Operations & Algebraic Thinking
Students develop an understanding of the meanings of multiplication and division of whole numbers through activities and problems involving equalsized groups, arrays, and area models; multiplication is finding an unknown product, and division is finding an unknown factor in these situations. For equalsized group situations, division can require finding the unknown number of groups or the unknown group size. Students use properties of operations to calculate products of whole numbers, using increasingly sophisticated strategies based on these properties to solve multiplication and division problems involving singledigit factors. By comparing a variety of solution strategies, students learn the relationship between multiplication and division.
