There are two tables in a room, and on each table are three bags. If each bag contains 10 oranges, how many oranges are in the room?

To help us find the number of oranges that there are in the room, we first need to find out how many bags there are. The first piece of information that we read in the problem tells us that there are two tables in a room. This bar can represent our two tables.

And the sentence carries on. On each table are three bags. So to represent this, we can divide both of our bars into three. And to find the number of bags, we need to find two lots of three. And of course, we know the answer to this is six. There are six bags in the room.

So what we need to know now is how many oranges there are per bag. And we can find this out from the start of the question right at the end, “if each bag contains 10 oranges.” So on our bar model, let’s label each of our six parts with the number 10. We have six lots of 10 oranges. This is what the question is asking us to find out. How many oranges do we have altogether? In other words, what is six times 10? Let’s skip-count in tens six times to find the answer. 10, 20, 30, 40, 50, 60. Six times 10 equals 60.

If there are two tables in a room and on each table are three bags, and if each bag contains 10 oranges, then the way to find out the number of oranges that there are in the room is to multiply two times three times 10. Well, we did this, and the first step we did was to multiply two by three. This gave us the calculation six times 10. We knew we had to find six lots of 10 to find the answer. Six multiplied by 10 equals 60. And so we know there are 60 oranges in the room.
