We just released a new version (1.9.0), and the lessons have been made
shorter (mostly 30-40 questions). "Sums to 15" is now 30 questions.
The old versions exhaustively covered every single possibility that
fit the question criteria, whereas now the students just get a random
sampling (randomly selected every time).
Go to http://tux4kids.alioth.debian.org for the new version (Windows
binary or source code). If your school is on Mac, I hope to get
something out fairly soon.
Best,
David Bruce
