Below are all previous MOAA competitions, sample problems, and solutions. Note that the sample problems and sample solutions are bundled into one document.
MOAA 2024
MOAA 2024 was held both in-person and virtually and consisted of four rounds: Speed Round, Accuracy Round, Team Round, and Gunga Bowl. Every problem on each round was solvable and computationally feasible with middle school mathematical techniques; no calculators or computational aids were necessary for any problem.
MOAA 2023
MOAA 2023 was held both in-person and virtually and consisted of four rounds: Speed Round, Accuracy Round, Team Round, and Gunga Bowl. Every problem on each round was solvable and computationally feasible with middle school mathematical techniques; no calculators or computational aids were necessary for any problem.
MOAA 2022
MOAA 2022 was held both in-person and virtually and consisted of four rounds: Speed Round, Accuracy Round, Team Round, and Gunga Bowl. Every problem on each round was solvable and computationally feasible with middle school mathematical techniques; no calculators or computational aids were necessary for any problem.
MOAA 2021
MOAA 2021 was held virtually and consisted of four rounds: Speed Round, Accuracy Round, Team Round, and Gunga Bowl. Every problem on each round was solvable and computationally feasible with middle school mathematical techniques; no calculators or computational aids were necessary for any problem.
MOAA 2020
MOAA 2020 was held virtually and consisted of three rounds: General Round, Theme Round, and Gunga Bowl. Every problem on each round was solvable and computationally feasible with middle school mathematical techniques; no calculators or computational aids were necessary for any problem.
MOAA 2019
MOAA 2019 consisted of four rounds: the Speed Round, the Accuracy Round, the Team Round, and the Gunga Bowl. Every problem on each round was solvable and computationally feasible with middle school mathematical techniques; no calculators or computational aids were necessary for any problem.
MOAA 2018
MOAA 2018 consisted of three rounds: the Individual Round, the Team Round, and the Gunga Bowl. Every problem on each round was solvable and computationally feasible with middle school mathematical techniques; no calculators or computational aids are necessary for any problem. We were pleased by the strong performances of individuals and teams at the first MOAA!
