Anthony has three boxes of plates. Each box contains five plates. How many plates are there in total?

In this word problem, we’re being asked to calculate the total number of plates Anthony has. We can see that Antony has already drawn a bar model to represent the problem. Each of the different colored bars represents one box of plates. There are three different colored bars to represent the three boxes. And Anthony has drawn five squares inside each bar because each of his three boxes contains five plates. Anthony has also written five plus five plus five equals what. So we need to calculate three lots of five.

Adding three fives is the same as multiplying five by three. We can calculate five plus five plus five or five times three by counting forward in fives three times along our number line. Five, 10, 15. Five plus five plus five or five times three equals 15. If Anthony has three boxes of plates and each box contains five plates, then he has 15 plates in total.
