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+1=?
The answer is 10. A child who answers 8 probably took away instead of adding.
- 2+1=?
The answer is 3. A child who answers 2 probably counted one too many or too few.
- 7+2=?
The answer is 9. A child who answers 7 probably answered with one of the numbers shown.
- 3+7=?
The answer is 10. A child who answers 0 probably lost track of the ten.
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.
