The Digit Dodecathlon is a great way to practice your addition to the next 10 or 100. Click the answer to make 10 or 100. A wrong answer will add three seconds to your time. Try to beat your fastest time, or log in under a full Scratcher account that can set cloud variables to set a new best time on the score board! Be sure to check out my book of weekly 4th grade Scratch/math lessons. http://goo.gl/pHF6Hd
Thanks to Kevin McAuliffe for the game music, Lost in Transposition. This game uses cloud variables to store the top 10 scores in a high score table. In order to set a high score you must be logged in as a full Scratcher (not just a new user). Read the cloud faq for details. Because cloud variables are still experimental, your score still may not save. If it doesn't, you don't need to tell me unless you think you've found an actual bug.
