Worksheet: Adding One-Digit Numbers by Making Ten

In this worksheet, we will practice adding two one-digit numbers by first making ten.

Q1:

Find an expression that has the same answer as 6+8.

  • A8+5
  • B9+4
  • C10+4
  • D10+3

Q2:

Fill in the blank: 7+9=10+.

Q3:

One way to make addition easier is to use addition facts that we already know.

Let us try to find 7+8 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 7+8 is the same as 10+5 which makes 15.

Now you have a go. What is 6+9?

Q4:

Ethan is adding by making 10.

Which calculation should he do first?

  • A9+1=10
  • B9+5=14

Which calculation should he do next?

  • A10+6=16
  • B10+5=15
