Why get the bundle
- Facts to 20 take real repetition. Cards, games and bingo let children see these sums many times without the work feeling like one long page.
The problem
8 + 5 is where counting breaks down
Once a sum crosses 10, finger counting runs out. Children need a way to see the ten inside the problem.
Crossing ten
8 + 5 means 8 + 2 first, then 3 more. Without that idea, children count on from 8 and often end on 12 or 14.
Counting on by ones
Counting forward 7 steps is slow, and one skipped number gives a wrong answer that looks fine.
Doubles and near doubles
Facts like 6 + 6 and 6 + 7 are easy to learn but easy to overlook, so children count them out each time.
Problems go to 20 so children meet the crossing-ten cases directly. The facts invite make-ten and doubles, and the answers can be checked.

Add to 20 by making a ten
Break one number to build ten, then add the rest.
- 4 + 6 = 10
- 5 + 4 = 9
- 1 + 3 = 4
- 7 + 8 = 15
- 4 + 15 = 19
- 4 + 14 = 18
- 7 + 10 = 17
Who it’s for
Built for the kitchen table and the classroom.
Parents & homeschool
Put ten counters in a ten frame or egg carton, and show how 8 + 5 fills the frame first. Then your child tries 9 + 4 alone.
Teachers
Fits a first-grade unit on strategies. Use the cards for centers and the check pages to see who needs make-ten reteaching.
Intervention & tutors
The crossing-ten facts are the likely gaps. These pages let you target them without repeating easy sums.
