Test your multiplication skills and race the bat. Each time you click on the correct answer the cat will move forward. Each incorrect click will cause him to go backwards. The first runner to reach the edge of the screen wins the race. Winning the race will cause the level to increase (up to 3) or you can click on a level number to set it for the next race. I also works pretty well on an IPAD: http://phosphorus.github.io/#119431009 And Cheddargirl mentions that it works well on her touch screen computer and probably works well on all touch screen devices. If you try this, please let me know.
This project has click-able numbers that change to Yes when you click on the correct answer or X if your answer is wrong. This is based on MrHills project http://scratch.mit.edu/projects/31372/ from 2007. And thanks to user nXIII for writing the phosphorus utility that I mentioned above.
