The age on each topic is the age it was designed for, based on typical US school math. Schools in other countries teach topics in a different order, so treat the age as a guide and start where your child is comfortable.
Not sure which age to pick?
Start one age below your child's age. Easy wins build confidence, and you can move up at any time. If a topic is too easy, jump to the next age. You can also browse by subject and build a custom course.
How the practice works
Each practice round has 10 questions. Your child can type the answer or tap a choice, gets a second try, and sees the correct answer and a short hint when needed. Questions are generated fresh each time. It is free, with no sign-up and no ads, and progress and stars are saved on your device only.
