Math Facts Fluency: Easy-to-use, built-in rewards and excellent reporting. The only app you'll need to ensure your child is completely fluent in addition and subtraction math facts.

What parents say about our awesome apps:
*** 5 stars! My son tried other apps, but after using them, I couldn't tell how well he knew his math facts. Was he done? Did he still need practice? With your app, I know exactly how he is doing - and best of all, he LOVES working for the reward game.
*** 5 stars! I like how my son can progress independently. The timer feature really ensures fluency. His recall is MUCH improved. Thanks!


Math Fact fluency is *vital* for math success. Fluency frees up your learner's working memory, allowing more "brain space" for problem solving. Make math easier for your child by ensuring they know their math facts fluently (should be able to answer in about one second!)

Math Facts Fluency Builder provides:

-- Addition and subtraction math facts introduced in learnable groups.

-- Built-in timers to ensure fluency at all levels. Earlier levels allow more time. Final levels require FAST answering!

-- Students progress only when mastery of the current skill is demonstrated.

-- 'At a glance' reporting shows you instantly how your learner is progressing.

-- The fun Reward Center motivates even hesitant learners.
