Half of six equals what?
Here we have six blocks. We have to find a half of six. To find a half, we need to divide six into two equal groups. Each group is a half. Now we just need to count how many blocks there are in each half: one, two, three. Half of six is three.
Another way to find the answer would be to think about which number is halfway between zero and six. It’s number three. The answer is three. Half of six is three.
