Our latest story problem challenge, October 24-28, 2016 More Information: wa.algebrachallenge.org Riddle Books is best suited for grades 3 - 7, with a little wiggle room on either end depending on reading and math skill. You can try a demo of the game right now at: wa.algebrachallenge.org/software
Students of all levels and grades with an interest in math are welcome, though! Private schools, home school groups and math clubs are also invited. There is no limit to how much time each student can use to play during this period, but we recommend at least 2 hours of game play spread throughout the challenge period. This is usually enough time to complete the game, even without any knowledge of pre-algebra. Take as much time you need; this is not a race!
Signups begin October 3rd. Brought to you by the Center for Game Science, University of Washington
