XtraMath does one thing and does it well: it builds math fact fluency through short, focused daily practice. Students spend about 10 minutes per day answering math facts (addition, subtraction, multiplication, division) against a timer. It tracks which facts a student has mastered and which still need work, automatically focusing practice on the gaps.

This is not a curriculum · it's a supplement. It pairs with any math program to ensure that basic fact recall becomes automatic, freeing up mental energy for more complex problem-solving. A number of homeschool families use it alongside conceptual programs like Singapore Math or Math-U-See where fact fluency isn't heavily drilled.

What to Know

XtraMath is completely free for families, supported by donations. The interface is deliberately simple , no games, no rewards, no distractions. Some children find this refreshing; others find it boring. For the latter, Reflex Math (a paid alternative) offers the same skill-building with gamified elements. But for families who want a free, no-nonsense daily math facts practice tool, XtraMath is hard to beat.
