This is a variety of basic activities to help students understand multiplication, division, and the relationship between them. For models of multiplication they use equal groups, arrays, and equal groups arranged on a number line. The option to use Cuisenaire Rods is included. There are illustrations of and situations including both partitive and measurement division. Students place and/or draw objects in a given number of equal groups (partitive division) and place and/or draw objects in groups of a known number to the total (measurement division). Fact families are applied to problems. We end by discussing and measuring/cutting paper to model division as repeated subtraction of equal groups.
Detailed teaching notes and a Smartboard 14 file are also included.
