Side-by-side comparison
Khan Academy vs Prodigy Math
A side-by-side from Khan Academy and Prodigy Education.
Prodigy and Khan Academy both show up on every "free homeschool math" list, but they're targeting different jobs and different children. Khan is a complete K–12 math curriculum with instructional videos and a mastery engine. Prodigy is a fantasy roleplaying game where math questions gate every battle. Families comparing them are usually deciding between rigorous self-paced learning and turning math into a game so a resistant kid will actually do it.
Khan Academy covers PreK math through Calculus with short video lessons, practice problems, unit tests, and mastery tracking. The platform is genuinely free, donation-funded, ad-free, and standards-aligned. Khan works as a primary math spine for self-directed students or as a no-cost supplement to a print curriculum. It also includes AP courses, free official SAT prep, science, history, and humanities. The trade-off is engagement — kids have to actually want to watch the videos, and there's no game loop to drag them in.
Prodigy is a Common Core- and TEKS-aligned math platform wrapped in a wizard-themed RPG. Students explore a fantasy world, battle monsters, and unlock new areas — but every battle requires answering a math question. The base game is free; paid memberships ($59–$119/year post-promo) add game perks like pets, gear, and currency. Prodigy is ESA-approved in many states. The genuine strength is that math-resistant kids will sit down and do Prodigy voluntarily. The honest weakness is that conceptual scaffolding is minimal — Prodigy rewards getting answers right, not understanding why. Reddit r/homeschool and Fairplay for Kids have flagged aggressive in-game upsell pressure as a constant complaint.

The verdict
How to choose
Choose Khan Academy if you want a real math curriculum, your student can engage with video instruction, or you need a free spine that scales through high school. Khan is teaching; Prodigy is practicing.
Choose Prodigy as a supplement (not a curriculum) if your child is 7–12 and avoids math, the gamification will get them to practice voluntarily, or you're in an ESA state and can cover the membership with state funds. Never use Prodigy alone — pair it with Khan Academy or a print curriculum that actually teaches the concepts. Pay attention to the in-game ads; some families turn off in-app purchases at the device level to manage the upsell pressure.
