A good place to try again.
The Sandbox is a collection of twelve interactive browser games created and maintained by BFC Labs. The money and six math games are designed around ages 6–9; choose the other games by reading confidence and puzzle experience. The games invite kids to experiment, get feedback, and try again. They are practice activities, not a test or a formal assessment.
Start with a concept your child already knows. Ask “How did you work that out?” and let them explain a move before making the next one. The six math games offer three skill trails each. Start Little Atlas with names visible, try Pixel Picnic’s practice row, or choose shorter Word Bloom words to find a comfortable challenge.
Play directly in a browser, with no child account required. A touch screen is great for moving objects; a mouse works too. Sound can be turned off in the games. Read the Sandbox guide for grown-ups →
