October 2015
The Eleventh Rockdale Math Competition
The 2015 tournament was held on Halloween!
Based on feedback from sponsors, we changed our format slightly to include four-student teams instead of six-student teams. We had a total of 114 four-person teams registered this year, which meant that some schools were turned away due to space, just like last year.
As with the previous few years, we offered an ARML-style competition, with a Power, Team, Relay, and Individual rounds. Each school was invited to bring a four-student teams in each of middle school, junior varsity, or varsity. The Relay round was changed slightly. This year, we allowed all four team members to work on the problems together, but the answer each questions after the first, you had to use answers to the previous problems.
As with last year, we continued the weighting of the Individual Round problems based on how many participants incorrectly answered each question (see the October 2013 page for more details). This table shows the percentage of participants who got each problem incorrect, and thus, these were the weights assigned to each problem.
The competition papers will be included in the second “Problem Book” for the years 2015 to 2024.
Trophies were awarded to the top 3 teams in each of middle school, junior varsity, and varsity per classification, and the top 12 middle school individuals, the top 12 JV individuals, and the top 12 varsity individuals were each recognized with a trophy. Additionally, the overall first place team winners won a Rockdale Math Competition T-shirt and copies of Math Horizons, a magazine published by the Mathematical Association of America.
Listed here are all team rankings per level and the top individual winners in each category.
