This is a tool to help children (and adults) memorize single-digit mathematics. Math work is much easier if you can immediately solve 7+8 or 3×9.
The goal: Get as many math facts correct in 30 seconds. Get none wrong. After a 30-second round, get a breather and try to break your score.
How to play: Click the "Start" button. You will be shown a math fact, such as 2+5. You will be shown five random answers. Click on the correct answer. Another math fact will instantly appear. If you click on the wrong answer, a delay will occur, eating up your time. How many math facts can you get correct in 30 seconds?
Parents: You can set what is tested in the settings menu. You can turn on/off addition, subtraction, multiplication, and division. All math facts will be single-digit, though the answer may be two digits.
I made this for my children. I hope others find it helpful. Feel free to use this tool. There is no cost or fee or license or any other form of restriction. You can even download it and use it on your personal computer if you so wish.
