A web-based app that helps children build math fact fluency through adaptive spaced repetition in short daily practice sessions.
About
A look at mathbuilders.com
Math Builders is a math fact fluency app designed for parents and teachers of children ages 6–12. It uses proprietary time-aware spaced repetition to help children build fast, automatic recall of multiplication, division, addition, and subtraction facts through short 2-to-5-minute practice sessions.
The app tracks the strength of each individual fact in a child's memory and serves it back at the precise interval that maximizes retention, reviewing facts near the forgetting curve rather than on a fixed delay. This approach keeps each session focused on the facts that need attention most.
Math Builders is designed as a supplement alongside school math, not a full curriculum replacement. It works for individual parents, homeschool families, classroom teachers, and tutoring centers. The app provides a colorful fluency map showing which facts are mastered, due for review, slow, missed, or ready for the next review, along with progress forecasts and weak-fact worksheets.

Questions
How is this different from flashcards or Khan Academy?
Flashcards review every card on a flat schedule, wasting time on facts already mastered. Khan Academy teaches concepts, not fact fluency. Math Builders tracks the strength of each fact in a child's memory and serves it back at the precise interval that maximizes retention using spaced repetition, the same engine used by tens of thousands of medical students worldwide.
What ages is this for?
Math Builders is designed for ages 6–12, covering second grade through middle school. Younger learners build addition and subtraction fluency, while older learners drill multiplication and division. The first session adapts quickly to provide the right level for learners of different ages.
Can my child get faster results with longer sessions?
No. Memory consolidation requires sleep and time between reviews. Two short sessions on different days produce dramatically more durable retention than one 30-minute session. Sessions are intentionally capped at 5–7 minutes because more minutes per day will not accelerate learning.
How much does it cost?
Math Builders is free to start with one child and six core packs covering all four operations. Premium plans include a monthly plan at $11.99/month, a yearly plan at $99.00/year, or a 3-year plan at $189.00 billed every 3 years, each unlocking combined packs, through-24 facts, additional learners, full fluency maps, and personalized worksheets.
Is my child's data safe?
Privacy, COPPA, FERPA, and Terms pages are published and linked in the footer of the website, allowing parents to review the privacy policies before using the app.
