Division Hidden Array Card
Multiplication and division both involve equal-sized groups and a total amount. With multiplication, we know the number of groups and the size of each group. The total is unknown. However, with division we know the total amount, but need to determine either the number of groups or the size of each group.
Because of this relationship, multiplication is considered the inverse operation of division. Using multiplication is the most effective thinking strategy for helping students to learn the basic division facts.
