Jennifer has three bars of chocolate. Each bar contains two pieces of chocolate. Write an addition sentence to show how many pieces of chocolate there are.

We know that Jennifer has three bars of chocolate. We’re also told that each of these bars contains two pieces of chocolate. So, we need to divide each of Jennifer’s bars into two pieces. The first bar has two pieces of chocolate. The second bar has two pieces of chocolate, so does the third. So now, each bar has two pieces.

We could calculate how many pieces of chocolate there are in total by adding together three lots of two. Two plus two plus two equals six. If Jennifer has three bars of chocolate and each bar contains two pieces, she will have six pieces of chocolate altogether. The addition sentence which shows how many pieces of chocolate there are is two plus two plus two equals six.
