iPracticeMath is a completely free math-practice site for grades 1 through 9. Younger kids might need support to move through practice sessions while older kids will need reminders not to worry about constantly being right. Large or homeschooling families, as well as teachers who work with lots of ages, will appreciate the one-stop-shop range of concepts. If kids want to track progress and view certificates, they need to register with the site, but it isn’t required. Unfortunately, kids will have to falsely report their age to create an account. Adults can register up to 25 students for free but don’t have the ability to oversee accounts or progress with a dashboard.
