Worksheets and the game work best together

Paper is good for careful working, and it's easy to see how a child got an answer. The game is good for fast recall, because it gets through far more facts in the same time and brings back the ones that wobble. Do a sheet on Monday, and play the game free on the other days.

Questions

Are the worksheets really free?

Yes. Print as many as you like for home or class. Each one carries our web address at the bottom, and that's the only catch.

Do they come with answer keys?

Yes. Tick Answer key and it prints on its own page.

Can I send a whole class the same sheet?

Yes. Tap Copy link and everyone who opens that link gets the same numbers.

An app is on its way

We're building a Sumtown app for iPhone with the parts that need a real app: offline play for car rides, a town map that remembers how far your child got, and a parent report on every fact. Until then, the whole game is free right here.
