The mistakes behind most wrong answers
A wrong answer in fractions of the same size 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.
Which fraction is the same size?
34The answer is 68. A child who answers 64 probably changed the top or the bottom, but not both.
Which fraction is the same size?
13The answer is 26. A child who answers 35 probably added to both parts instead of multiplying them.
Which fraction is the same as 6?
The answer is 61. A child who answers 16 probably wrote the fraction upside down.
Which fraction is the same as 3?
The answer is 31. A child who answers 33 probably mixed up two similar numbers.
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.
