Make 10: number bonds with a ten-frame and cherries
For parents of children in Year 1 learning to add and subtract across ten. Each sum is done in the school's steps: fill the ten, split the other number, then finish. Free, no sign-up.
How to use it with your child
- Choose Make 10 (adding across ten), From 10 (taking away across ten) or Split (number bonds up to 10).
- Tap Start on this device. Each sum comes in small steps with a ten-frame: how many make 10, what's left, and the answer.
- A wrong step can be tried again straight away; the sum counts as right first time only if every step was.
- Print sheet gives cherry worksheets: the two empty circles under a number are for the split.
Which school years it suits
Year 1 (P1, 小1, 초1), when sums across ten are taught. Split (가르기와 모으기) also suits older preschoolers.
The method schools use
Japanese schools call it さくらんぼ計算 (cherry calculation), because the split looks like two cherries on stems. Korean Year 1 teaches 가르기와 모으기, and Singapore's number bonds are the same idea: make a ten first, then add what's left.

Questions parents ask
Why not just learn 8 + 5 = 13 by heart?
In time children will. The make-10 steps give them a reliable way to get there, and it is how Year 1 classes in Japan, Korea and Singapore teach it.
Are the cherries red?
No, they're blue: on Pencilhop red is only used for marking.
