The mistakes behind most wrong answers
A wrong answer in adding up to 10 is rarely random. These are the ones that come up most often, each on a real problem — worth knowing before you mark a sheet, because the fix for each is different.
- 9+?=10
The answer is 1. A child who answers 2 probably counted one too many or too few.
- 3+?=10
The answer is 7. A child who answers 3 probably answered with one of the numbers shown.
- ?+1=3
The answer is 2. A child who answers 3 probably added instead of taking away.
- 🐛🐛🐛🐛🐛🐛🐛🐛🐛🐛9+1=?
The answer is 10. A child who answers 8 probably took away instead of adding.
In the app, every wrong answer is matched against mistakes like these, and the weekly email tells you which one your child keeps making — in those words, not as a percentage.
