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.
