Khan Academy is great but has real limitations for younger kids — lecture videos require reading ability and sustained attention. Here are the best alternatives, especially for K–5 learners.
Try #1 Alternative Free →Khan Academy is exceptional and free — and it's genuinely the best free math resource on the internet. Most parents who look for alternatives are dealing with one of these issues: (1) their child is under age 10 and struggles to sit through lecture videos, (2) they want narrated, interactive lessons rather than videos that can be paused and re-watched passively, (3) they want a tool that covers science and social studies at the same depth as math, or (4) they want more engagement and interaction than a video + problem set provides.
Free sites like Khan Academy: CK-12 (K–12 math and science), Zearn (K–8 math), Khan Academy Kids (ages 2–8). Prodigy Math has a free tier.
If your child won't sit through videos: Lumi Academy (Pre-K–12, narrated, tap-to-answer lessons, up to 8 kids on one plan).

The biggest difference from Khan Academy: Lumi is interactive and narrated rather than video-based. Instead of watching a lecture, kids hear Lumi explain a concept while seeing it illustrated, then answer questions to confirm understanding — all narrated, all interactive. A strong fit for ages 4–12, and it continues through 12th grade with Lumi High. Covers math, ELA, science and social studies plus electives, with mastery-based progress.
IXL is the strongest pure practice tool for math and ELA K–12. Deeper skill taxonomy than Khan in both subjects. The trade-off: no instruction whatsoever — it's drills only. Best used alongside something that teaches (like Lumi or Khan).
Khan Academy Kids is the animated, interactive version of Khan Academy built for ages 2–8. It's free, covers Pre-K through 2nd grade math and ELA, and is genuinely well-made. Best free option for early learners. Tops out at about 2nd grade level.
If engagement is the primary concern (keeping a reluctant learner practicing math), Prodigy's game format can be more motivating than Khan for grades 3–7. Math only, no instruction, but the RPG loop creates motivation that pure practice platforms lack.
A nonprofit math program that is free for families at home. Like Khan Academy it teaches with short videos, but every lesson is broken into guided, interactive practice steps, which younger kids often find easier to follow than a longer lecture. No ads. Math only, so you still need something for reading, science and social studies.
A free nonprofit library of digital textbooks, simulations and adaptive practice. It is one of the closest free sites to Khan Academy for math and science, and it suits middle and high schoolers who read and work independently. Less suited to young kids who need a guided, spoken lesson.
The closest websites like Khan Academy are Lumi Academy (narrated and interactive, Pre-K–12, 24+ subjects), CK-12 (free math and science), IXL (deep practice in math and ELA), Khan Academy Kids (free, ages 2–8), and Prodigy (game-based math). Which one fits depends on what you actually need: Khan teaches by video, so if the reason you're looking is that your child won't sit through videos, you want an interactive option rather than another video library.
Khan Academy's math is its strongest subject by a wide margin, and its science and social studies are thinner at the elementary level. If you need all four core subjects at consistent depth, look for a full curriculum rather than a practice platform. Lumi Academy covers math, ELA, science and social studies from Pre-K through 12th grade, plus electives, which is the main structural difference.
Khan Academy competitors fall into three groups. Practice platforms (IXL, Prodigy) drill skills but don't teach. Full curricula (Lumi Academy, Time4Learning, Acellus) teach and track a scope and sequence. Early-learning apps (ABCmouse, Khan Academy Kids) cover Pre-K through about 2nd grade. Khan sits between the first two — it teaches, but it isn't a curriculum you can homeschool from on its own.
This is the most common reason parents go looking. Khan's lecture-and-practice format assumes a child who can read fluently and sit still for a video, which typically means age 10 and up. For ages 4–10, look for narrated lessons where the child answers as they go. Khan Academy Kids is the best free option but stops around 2nd grade; Lumi Academy runs narrated lessons through 12th grade.
Khan Academy itself is genuinely free and donation-funded, which is rare and worth saying plainly — no other option on this page matches that. Khan Academy similar websites that charge generally do so because they add curriculum structure, progress tracking, and parent reporting. If free is the requirement, Khan Academy, Khan Academy Kids, CK-12 and Zearn are the honest answers. If you need a full homeschool curriculum with records, expect to pay for it.
