We continue looking at simple situations where multiplication is useful, such as the total cost of so many items, or a group of objects arranged in an array. Sometimes the question is not given but we need to figure out WHAT could be solved or found out. Sometimes what the question is asking is NOT the total but one of the factors. This helps children become better problem solvers, because they cannot rely on mechanically multiplying the two numbers given in the problem.
