Scarlett put her counter on four and then moved it forward three spaces. She’s saying seven is three more than four. Then we got a picture of underneath saying what is four more than two. Help Scarlett find the missing number.

In the first picture, we can see that Scarlett has added two numbers together. We’re told that she’s put her counter on four. And we can see this on the number track, can’t we? And then she’s moved it forward three spaces: one, two, three. So what Scarlett has done here she started with four, she’s added on three, and she’s found the answer to four plus three, which is seven. Seven was the number that she ended up on. And that’s why she can say seven is three more than four.

Underneath we can see another picture of a number track, and this time Scarlett is going to add some more numbers together. She says what is four more than two. And we can see that Scarlett has put the counter on two, ready to begin. So, two is her starting number, and she wants to find four more than two. So the calculation she’s working out is two plus four. What is four more than two? We need to move the counter forward four spaces: one, two, three, four. We’ve ended on the number six, and so Scarlett can say six is four more than two. Two plus another four is six. We found the answer by counting on. Scarlett’s missing number is six.
