About this worksheet
Making a ten is a strategy for facts like 8 + 5. Instead of counting on five times, a child moves part of the second number over to finish a ten, then adds what is left.
Ten plus something is easy (10 + 3 is 13), so the hard fact becomes two easy steps. It is the same idea a child will later use for 38 + 5 and 98 + 7.
A worked example
8 + 5 = ?
- 8 needs 2 more to make 10.
- Split 5 into 2 and 3.
- 8 + 2 = 10.
- 10 + 3 = 13.
Answer: 8 + 5 = 13
The common mistake
What it looks like: Moving 2 over to make ten, then adding the whole 5 again: 10 + 5 = 15.
Why it happens: The child forgets that the 2 came out of the 5, so only 3 is left.
How to fix it: Cross off the part that moved. Say it aloud: "5 is 2 and 3. The 2 made the ten, so 3 is left."
