Games
Three games a child can play alone: temperatures below zero, equations on a balance, and the roles in a food web. No timer, and stars are saved in this browser only.
Negative numbers
Below Zero
Two temperatures. Tap the colder one — or the warmer one. Read the question.
Play Below Zero
Equations
Balance It
An equation on a balance. Pick the value of n that makes it level.
Play Balance It
Ecosystems
Food Web
An Alberta plant, animal or fungus. Is it a producer, a herbivore, a carnivore, an omnivore or a decomposer?

How these are built
- A wrong answer teaches. The number line appears, the balance tips and shows the check, or the animal's real diet is given.
- The wrong options are the real mistakes. −12 read as bigger than −7, adding instead of undoing, a bear called a carnivore.
- 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.
