What kids do
“Count the dots in each group. Add them together. Write the answer.”
Teacher tip
Read the plus sign as “and” for young kids: three dots and two dots. Let them count all, then count on as they get ready.
How to use it
- Warm up with two minutes of facts out loud before kids start.
- Ask kids to circle the problems they are sure of first, then go back to the tricky ones.
- 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
- Show me one problem where you had to regroup. Why?
- Which problem was the hardest? What made it hard?
