NumberClub exists because you’re more likely to remember 4 x 7 = 28 the more you care about knowing it, and the reason to care lies within interesting mathematics rather than because a person or computer keeps expecting you to answer it.

One of NumberClub's underlying principles is to build feedback into every choice a student makes, so every maths question becomes more than "Woohoo, you got it right!" or "Boo, you got it wrong." It's the difference between judge for yourself and being judged.
