Free usually means one of two things: a full curriculum with no cost at all, or a free extra you add to a paid program. Here's what's genuinely free, in both categories.

Try it with free selectedFree full curricula are rare. Across the 31 math programs we track, only two, Khan Academy and Easy Peasy, cost nothing and cover a full year on their own.
Free supplements are more common. Zearn and Prodigy don't teach a full year by themselves, but they're free ways to add practice or a video explanation alongside a paid program.
Free still means an honest trade-off. Free programs tend to ask more of the parent, offer less built-in structure, or use ads and upsells (Prodigy's optional memberships, for example). Read each program's profile for the specifics.
Free, self-paced video lessons and practice from early math through calculus
Free online Christian curriculum with every day's math lesson laid out, K through high school
Yes. Khan Academy and Easy Peasy are both free from grade K through high school. Neither is flashy, but both cover the material.
Usually thinner support: less structure, fewer built-in manipulatives, or, for a game like Prodigy, in-app upsells aimed at kids. None of that makes them unusable, just worth knowing going in.
Yes, and many families do. A free program like Khan Academy or a game like Prodigy works well as extra practice next to a paid core curriculum, at no added cost.
How this list is made: each program is scored against the needs above using features documented in parent reviews and publisher materials (sources are listed in each program's profile). It's a starting point, not medical or educational advice.
