A large site of educational games and printables for grades K-8, built over more than 20 years by a former elementary school teacher. It covers math, reading, geography, history and science, with classics like speed-math and fraction games plus interactive maps. Kids play in the browser for free with ads. Teachers or parents can pay to remove ads, unlock the full library, and use a dashboard, tournaments and score tracking in some games.
Our take: A handy free game library for elementary classrooms and home practice; families who want an ad-free, structured program should look at paid alternatives.
Checked in a browser
A browser check on 2026-10-25: what loads, the ads and trackers we saw, and what a child meets first. Not a hands-on test.
| Child safety: 2 out of 5 | Google AdSense programmatic ads loaded (2 ad frames), and Login / Sign up sits at the top. |
|---|---|
| Data: 2 out of 5 | Google's ad network (doubleclick, googlesyndication) and Google Tag Manager loaded, setting a doubleclick cookie. |
| Ease: 3 out of 5 | The first screen is a pitch to teachers to subscribe; the game map below it is colorful but small on a phone. |
| Cost honesty: 3 out of 5 | Large Subscribe Now and Gift a Subscription buttons, and an $89 'forever' subscription offer, lead the page. |
What we found
- Contacted 10 outside sites; 2 were Google ad networks.
- 2 Google ad frames loaded in 15 seconds.
- The first card says 'Subscribe Now' and 'Gift a Subscription'; page text advertises an $89 forever plan.
- Free resources are listed below the subscription pitch.
From the test: Many free K-8 learning games, but with Google ads and a subscription pitch first; younger children need a grown-up to steer.

Be Internet Awesome: Interland
Google · ages about 7-12
A good free starting point for online safety with kids 7-12, best paired with family talks since the game alone did not change behavior in testing.
