Worksheet: Adding One-Digit Numbers by Making Ten
In this worksheet, we will practice adding two one-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 ?
Chloe added 7 and 6 by first making 10.
Now, she wants to add 8 and 7.
Which number should she write in the blue circle?
Which number should she write in the red circle?
What is 8 + 7?
Ethan tried to solve by using the making ten strategy, but he got the answer wrong.
Anthony was asked to solve .
Is his solution correct?
