Problems are expanded to those in which children can use multiplication combinations to figure out partitive (sharing) problems, where a  number (e.g., 24 candies) is divided into a given number of groups (e.g., 4 people)  the question is:  how many will there be in each group (how many will each person get?–6!)? A (see the middle column in the "Common Multiplication and Division Situations" document in Resources). We can think of this as 6 X _ = 24.
