MathBrush is being tested with a few parent groups, and every solution on the site is open to them — one household, all children. If you were given a code, it goes in once and this device remembers it.

65 worked examples are free without a code, two from every pattern. No account, either way.
The second fraction is of one piece, not of the whole.
In this one. Cut the whole into 6 units so that both fractions land on unit lines: the remainder is then 5 units, and 2/5 of 5 units is exactly 2 units — which is 2/5 × 5/6 = 1/3 of the whole.
A second fraction arrives after the first and is attached to a piece rather than to the whole — 'of the remainder', 'of what was left', or 'of the ones that were red'.
Children take the second fraction of the original total instead of the piece it was named against, which makes the amount come out too big.
