Word problems about party bags and snack packs hide multiplication and division. Look for clues. If you get equal groups and need the total, multiply. If you get a total and need to make equal groups or groups of a size, divide. Sharing equally is dividing too. If 20 grapes are shared among 4 friends, each gets 20 ÷ 4 = 5 grapes.
Division can also tell you how many equal pieces fit inside a total. This is called measuring. Ask yourself: how many groups of that size are in the total? Check by multiplying back: pieces times piece size should rebuild the total.
A ribbon is 28 cm long. Each piece needs to be 4 cm. Divide the total by the piece size: 28 ÷ 4 = 7 pieces.
To pick the right operation, look at what's missing. Know the groups and the size of each group? Multiply for the total. Know the total and the size of each group? Divide for the number of groups.
Multiply when you know the groups and need the total. Divide when you know the total and need to split it evenly.
