MobyMax: Personalized learning for every K-8 subject with lots of built-in student motivation so kids enjoy practicing. Students take a placement test and then receive practice in the skills they need help with. 

Khan Academy: K-12 interactive exercises and tutorials for a wide array of subjects. Your child will have a custom learning dashboard that lets him or her practice skills based on the individual level. Students can see how they’re doing and also receive fun rewards along the way like badges and points. 

NCTM Illuminations: K-12 activities and games for nearly every math topic. 

Math at Home: Excellent math stories and activities. Very age appropriate for Pre-K.

Vocabulary Spelling City: The best site for engaging, differentiated practice with spelling and vocabulary (use the built-in sets of words or help your child develop his or her own list!)

Electric Company: High-quality and engaging phonics, vocabulary and reading games for K-3.

Tynker: Coding games for kids in grades K-12

Learning Games Lab: Engaging, in-depth games on unique topics from elementary and middle schoolers, including food safety, water conservation, and more. Science teachers should check out the virtual labs and math teachers should check out Math Snacks and Monster School Bus. 

ABCMouse: Fun online practice for a wide variety of skills and subject areas for grades PreK-2. 

ABCya: K-5 ELA and math games, as well as various other topics (both educational and just for fun.) There’s also a large collection of games available as apps.

Sheppard Software: Top-quality games for every subject spanning PreK-8. Fun and easy to use. There are ads on the site, so be sure to remind your child not to click on anything to the left or right of the game.

PBS Kids: Great for younger students. There are educational and just-for-fun games, which you can sort by subject area and skill. Be warned that some games are premium and require a subscription. I also recommend the PBS CyberChase collection of math games.

FunBrain: Makes the list because kids return to the site again and again even when they have the choice to play non-educational games. The online books and comics addition is wonderful. It’s not the easiest site for kids to navigate independently if they’re looking for a specific game, but that’s mostly because there’s so much there.

BBC UK: Features a kid-friendly landing page that makes learning look like all fun and games, or use the schools-games page which organizes activities by subject area.

Utah Education Network: A curated collection of free useful and developmentally appropriate games from all over the web. Look in the sidebar on the right-hand side and click K-2, 3-6, or 7-12 interactives.

BrainPOP’s GameUp: Highly vetted free educational games for K-12 on a variety of topics. BrainPOP’s collection focuses on higher-level thinking skills and critical thinking rather than rote practice and includes topics such as coding and STEM skills.
