The competition, sponsored by the National Society of Black Engineers, aims to prepare students for math and science courses and standardized testing. It began Wednesday and will continue through Sunday.
The A.R. Johnson team won at the local level in October and beat out teams from six states to win the regional competition in November, earning a spot in this week's competition.
Competing in math is fun, team members say.
"There's more to math than just adding and subtracting," said Raquel Edwards, 16. "It's my favorite subject because you get to do different areas of it."
Teammate Lora Golden, 17, added: "I like math because it's the most exact thing out there. It doesn't really change."
Try-Math-A-Lon has three parts: a progress assessment test; an engineering contest; and a quiz bowl. It includes averages, percentages and ratios, velocity and acceleration, word problems, unit conversion, and scientific notation.
There are also questions about the society's history and engineering, said adviser Aleks Holiday.
The experience will give the students a chance to grow, she said.
"I hope they go into the competition with a positive mind and the willingness to challenge themselves," she said. "They'll also have an opportunity to meet other students from all over and form some great friendships with them."
Other team members are Chantilly Jaggernauth, Brandon Herrington and Stephen Brown, all 18.
The team's math coaches, Anthony Stawiery and Jacqueline Wilder, are accompanying the team to the competition, she said.
The team members are a part of the NSBE Jr. chapter at A.R. Johnson. NSBE Jr. is for high school students and is under the society's umbrella.
The National Society of Black Engineers-Augusta alumni chapter sponsors the team's trips to the competition.
