There are four events to Math-Team-Matics - so really it's a Quadrathalon.
The structure of the competition is:
Team Challenge - open-middle problem that requires collaboration to solve within the time limit.
Individual Challenge - multiple choice problems trying to get at a different perspective than the usual quiz.
Relay Race - quick numerical problems that require the data from the runner before you.
Quiz Bowl - mix of turn-based and toss-up questions pitting one team against another.
Final Quiz Bowl - top two teams in each division face off in a winner takes all match.
Math content that is fair game for the competition is K-8 mathematics, plus high school algebra and geometry.
Here are some sample problems for the different phases. In the competition there will be an emphasis on fun and challenge.
Team ChallengeSampleHow many numbers from 1 to 20 can you compute using the digit 9 exactly three times and any mathematical operation +, -, x, /, sqrt, factorial, decimal point, etc, but no other numbers or digits. You have to use 9s as digits, not necessarily the number 9, so 9, 99, 9.9, etc. are all fair. Extension: 21-30!

Individual Test (Multiple choice)To make this collaborative, we drop the high and the low scores, make a team score with credit for any problem anyone on the team answered correctly, then average that with the three middle scores.Ten liters of a 30% acid solution are obtained by mixing a 25% solution and a 50% solution.
