A mixed round for the web. The app is times tables: to 15 for kids, to 25 for adults.
Bring it to your class.
- Make a class. Give it a name. No sign-up, no email, nothing to install.
- Put the link on the board. Students type a first name and play today’s Grid, on a Chromebook, a tablet or a phone.
- Watch the times come in. Who solved it, how fast, and how your classes compare.
Students’ names and times stay inside their class. We never ask for a school, a grade or an email.
This isn’t a kids’ problem.

The full game is on iPhone and iPad.
