Multiplication and Division

In this unit students

•  learn the meaning of multiplication and division;
•  learn the relationship between multiplication and division;
•  understand and use the commutative property of multiplication.

Students understand multiplication as finding how many objects there are in a number of equal-size groups, and division as finding the number of groups or the number of objects in each group. Fluency with multiplication and division within 100 builds over an extended period of time, and so work towards fluency begins here. Critically, division is developed in terms of its relationship to multiplication in this and the next two sections.
