Count the hats. Write a number to show how many there are.

In the picture, we can see some hats that we’ve got to count, and we need to write our answer as a number to show how many there are. Before we start, can you see anything interesting about the way that these hats have been arranged? Just like we often put counters into ten frames to help us count and learn about numbers, we can see that these hats have been put in ten frames too. Perhaps we can use this to help us count them. What do you notice about the first ten frame? It’s full, isn’t it? There are no gaps. How many hats do you think make up a full ten frame? There must be 10 hats. That’s why we call this a ten frame.

So in the picture, we can see 10 hats and then some more hats. How many more? One, two, three, four, five, six more. The number of hats is six more than 10. What number is six more than 10? It’s time to count the hats. One, two, three — wait a moment. We don’t have to start counting at one, do we? We already know there are 10 hats in this first ten frame. So why don’t we point to the first ten frame and say 10 and then start counting from 10. 10, 11, 12, 13, 14, 15, 16. We’ve counted 16 hats altogether. We can see that there are six more than 10. And six more than 10 is 16.

Now, we know we write the number 16 using words as the number six followed by teen, sixteen. But our question asked us to write the answer as a number. Do you remember how to write sixteen as a number? Well, first, we need to write the number one and then the number six. A one followed by a six is 16. We counted the hats and then we wrote a number to show how many there are. There are 16 hats.
