Worksheet: Addition of Two One-Digit Numbers
In this worksheet, we will practice using ten frames to add two single-digit numbers by first making ten.
One way to make addition easier is to use addition facts that we already know.
Let us try to find by first making 10.
We need to add 3 more to 7 to make 10. So move 3 green squares over.
Now we have the same number of squares, but there are 10 in the first ten-frame, and 5 in the second.
So is the same as which makes 15.
Now you have a go. What is ?

Which number should she write in the red circle?
What is 8 + 7?
