The mistakes behind most wrong answers
A wrong answer in fractions written as decimals 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.
- 610+8100=?
The answer is 68100. A child who answers 14100 probably added before making the pieces the same size.
- 110+4100=?
The answer is 14100. A child who answers 14110 probably changed the bottom number too.
- 210=?
The answer is 0.2. A child who answers 2.0 probably put the digits one place out.
- 410=?
The answer is 0.4. A child who answers 0.45 probably counted one too many or too few.
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.
