The mistakes behind most wrong answers
A wrong answer in changing units 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.
7 minutes is the same as how many seconds?
The answer is 420. A child who answers 70 probably put the digits one place out.
2 feet is the same as how many inches?
The answer is 24. A child who answers 14 probably added instead of multiplying.
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.
