Challenge time for the Seniors Class! Go to a new website called MathRun . It's a simple game to practice your math skills. When you open the page, you'll see this screen in the middle of the window (I think it looks a little like a phone app, but it isn't. You play on your computer screen.)
Pay attention to how you control the screen: left arrow = correct answer, right arrow = wrong answer, up arrow = go faster.
MathRun has been online since January 9 this year (2010), and has an accompanying blog that highlights its development.
