Divide into three groups. 33 divided by three equals what.

In the picture, we can see a number that’s been modeled out of base 10 blocks. And when we read the instruction, divide into three groups, it’s this number that it’s talking about. It’s a number made from three 10s and three ones. It’s the number 33. And we can write what we need to do here in a number sentence. 33 divided by three equals what. Because our number 33 has been modeled for us in base 10 blocks, it’s already being broken up into its 10s and ones. And because there are three of each, hopefully you can see it’s going to be quite easy to split them up.

Let’s divide our 10s first of all. 10, 20, 30. We’ve got one 10 in each group. 30 divided by three is 10. Now let’s divide our ones blocks. One, two, three. Three divided by three equals one. Each of our groups has one 10 and one one. We’ve divided 33 by three by modeling it using place value blocks, then dividing the tens and the ones separately. 33 divided by three equals 11.
