Games

Three games a child can play alone: decimals built to catch the classic mistake, shapes named from their measurements, and the order of Canada's history from Cartier to 1905. No timer, and stars are saved in this browser only.

How these are built

  • A wrong answer teaches. The place-value chart appears, the deciding measurement is pointed out, the two events go on a timeline.
  • The wrong options are the real mistakes. 0.45 against 0.5, a rhombus that looks like a square, two events a few years apart.
  • Stars count first tries. Nothing is taken away for a wrong tap, and every round still ends with the right answer shown.
  • Nothing is sent anywhere. Stars are stored in this browser. There is no account and no advertising.
