A classroom has six tables. Each table has five children sitting on it. Complete the number sentence to show how many children there are altogether.

We know the classroom has six tables. And we know that each table has five children sitting on it. So to find out how many children there are altogether, we need to multiply six by five. We may not know our six times table. So we could work out six lots of five.

Our model shows the six tables as squares, and the orange dots are the five children at each table. A quick way to calculate the answer would be to count in fives. We’re counting the number of children on each table. And there are five children on each table. Five, 10, 15, 20, 25, 30. Six times five equals 30. There are 30 children in the classroom altogether.
