What kids do
“Add the three numbers. Tip: find two digits that make 10 first.”
Teacher tip
Have kids circle two numbers that make 10 before adding. It is a habit that pays off for years.
How to use it
- Use it as a timed sheet once a week and have kids chart their own score.
- Let partners check each other with a calculator after they finish.
- Do the first problem together under a document camera, then let kids finish on their own.
Watch for
Subtracting the smaller digit from the bigger one in each column (54 − 27 = 33). Ask kids to say “Can I take 7 from 4?” before they write.
Talk about it
- Which strategy did you use: counting on, making ten or a doubles fact?
- Which problem was the hardest? What made it hard?
