The Best Educational Websites for Kids in 2026

Khan Academy is a free, ad-free nonprofit site with math from kindergarten through calculus, plus science, grammar, history, computing and official SAT prep. Mastery points show what a child knows, and a parent account lets you assign work with due dates. Videos can feel dry for young kids, and it is not accredited, but nothing else free matches its depth for grades 3 to 12.

Best for: Grades 3–12 and homeschoolers who want a free core for math

PBS KIDS (pbskids.org) has a large library of free learning games and videos built around shows like Daniel Tiger and Wild Kratts, covering early math, reading, science and social skills. It is safe and simple for small kids and includes Spanish-language games. There is no learning path or progress tracking, so use it for play with a purpose rather than to teach a skill in order.

Best for: Ages 2–8 for free, low-stress learning play

Code.org, now branded CodeAI, offers free, ad-free coding courses from kindergarten through AP Computer Science A. The self-paced Express courses work at home for grades K–8, and the labs let older kids write JavaScript and Python. Many schools already use it, so kids may know it. Deeper middle and high school courses are built for a teacher, so a homeschool parent has to lead.

Best for: Grades K–12 kids starting coding at no cost

Scratch, from the nonprofit Scratch Foundation, is a free block-coding studio where kids build their own games, stories and animations and remix millions of shared projects. It runs in a browser with an offline app, and ScratchJr covers ages 5 to 7. It is an open studio, not a course, and the online community means kids see other users' comments.

Best for: Ages 8–16 who like making things

Starfall is a calm, ad-free nonprofit site that teaches letter sounds and early reading systematically, with some early math. Some activities are free, and a home membership costs $35 a year on starfall.com and does not auto-renew (October 2026). In-app subscriptions cost about twice as much. It looks dated and kids usually outgrow it by 2nd grade.

Best for: Pre-K to 1st grade readers on a budget

ABCya is a huge, well-organized library of short games sorted by grade from pre-K to 6th grade, covering math, reading, typing and art. It is free on the web with banner ads; Premium in the app costs $9.99 a month or $79 a year (October 2026). Kids find it easy to start, but games are practice rather than teaching, and many need mouse skills.

Best for: Pre-K to 6th grade kids who need fun, quick practice

National Geographic Kids is a free website with no login, packed with animal facts, science articles, quizzes, games and short videos with strong photography. It is ideal for curious readers ages 6 to 12 and for report research. It has no lessons or sequence, and the site uses interest-based advertising, so it is enrichment rather than curriculum.

Best for: Ages 6–12 who love animals and science facts

BrainPOP's short animated movies explain science, social studies, math, English and more with humor that kids remember, followed by quizzes and creative projects. Family plans cost $119 to $159 a year; homeschool plans with assignment tools cost $350 to $430, all with a two-week trial. Full features need a computer rather than the iOS app.

Best for: Grades K–8 families who want short explainer videos

Mystery Science starts each lesson with a real kid question, then guides a short video and a simple hands-on investigation using household supplies. Free mini-lessons are open to everyone; the homeschool membership costs $199 through June 30, 2027, or $259 with Mystery Writing (October 2026). It covers K–5 only and is light as a full curriculum past 2nd grade.

Best for: K–5 families who want engaging science with little prep

Education.com combines printable worksheets, workbooks, games and lesson plans organized by grade and skill for pre-K to 5th grade. A free Basic account has limited downloads; Premium is commonly $15.99 a month or $119.88 a year (October 2026), with one membership covering the whole family. Many public complaints are about auto-renewals, so set a reminder.

Best for: Elementary families who want printables plus games

Turtle Diary offers games, videos and printables across math, reading, science and typing for pre-K to 5th grade. It is free with ads, and the ad-free family membership costs $69.99 a year for up to five children (October 2026), one of the cheapest multi-kid plans around. The design is dated and it is practice rather than instruction.

Best for: Big families who want cheap, ad-free practice

Crash Course Kids is a free YouTube series with quick, clear, funny science episodes grouped into topic playlists that line up with common 5th grade standards. There is no sign-up. The creators provide no lesson plans or quizzes, the science episodes date from 2015 to 2016, and YouTube can surface ads and unrelated videos, so watch together or use a playlist link.

Best for: Grades 3–5 for introducing or reviewing a science topic
