Which of the following models represents 12?

Underneath the question, we can see some pictures of 10 frames. And you know 10 frames are a good way of representing or showing numbers. But which of our models represents or shows this number here? What is this number here? How would you say it?

When we see a one digit followed by a two digit, we know it’s the number 12. Now, there are two ways we could find the answer here. We could look at each of the models one by one and count the number of counters. That way, we could see which one has 12 counters.

But a quicker way to find the answer is to use what we know about the number 12. Where does the number 12 belong? We know that the number 12 is two more than 10. One, two, three, four, five, six, seven, eight, nine, 10, 11, 12. Now, which of our models shows two more than 10? Now, we know that a full 10 frame shows the number 10. Here’s a full 10 frame. So this shows 10, and then one more than 10. One, two, three, four, five, six, seven, eight, nine, 10, 11. This model represents the number 11, not 12.

This model shows a full 10 frame too. But how many more than 10 does it show? One, two. One, two, three, four, five, six, seven, eight, nine, 10, 11, 12. This is the model that represents the number 12. And if we quickly look at the other models, we can see two counters in the first one.

And now our last model only shows the number one. We know that the number 12 is two numbers after 10. And so the model that represents the number 12 is the one that shows a full 10 frame or 10 and then two more. 12 is two more than 10.
