The mistakes behind most wrong answers
A wrong answer in parallel and perpendicular 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.
How are these two lines arranged?
The answer is perpendicular. A child who answers parallel probably named a shape from the same family.
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.
