Emma wants to put these 12 blocks into groups so that there are three blocks in each group. Make groups of three. Which of these is equal to the number of groups she will have? 12 divided by three, 12 take away three, 12 plus three, or 12 times three. How many groups will there be?

We know that Emma will share her 12 blocks into groups of three. This calculation is equal to the number of groups she will have, 12 blocks divide or shared into groups of three. The second part of the question asks us, how many groups there will be? One group of three makes three. Two groups of three are six. Three groups of three is nine. And four groups of three makes 12.

Emma had 12 blocks. And she wanted to put them into groups, so there are three blocks in each group. So Emma was calculating 12 divided by three. This is the answer to the first part of the question. And if Emma divided her 12 blocks into groups of three, she would have four groups. The answer to the second part of the question is four. 12 divided by three equals four.
