North American most influential challenge on campus

Hosted by Canadian Mathematical Society-one of the world's leading authorities in math

Over 160,000 participants from more than 29 countries each year

7 different levels suitable for students from Grade 1 to Grade 12

Outstanding students are invited to more advanced science programs

Duration:October, 2022 - May, 2023(Online)


Caribou Contests is a global online math challenge sponsored by the famous Canadian mathematics professor Thomas Wolf and officially supported by the Canadian Mathematical Society. The challenge does not focus on “difficult” questions, but rather stimulates students' interest in mathematics through the “interactive” novel and interesting questions, and improves students' problem-solving skills. Since its inception, the Caribou Contest has quickly become popular in 29 countries around the world. Every year, 160,000 candidates in grades 1-12 compete on the same stage, ranking globally. Another feature of the Caribou Contest is that it is a point game. It provides 6 monthly exams in May of the coming year of October, and selects 5 best scores for rankings. It is an extension of the school math interest community activities and mathematics extracurricular activities. Learning provides a good platform.

Program Highlight

Different from traditional mathematical thinking challenge activities, caribou contest integrates mathematical problems into life through "interactive" novel and interesting problems, stimulate students' interest in mathematics, and improve students' problem-solving ability.Caribou games are definitely the most important part of the caribou contest. There are one or two interactive games for each round of questions at each level.Students enjoy the fun of math in games, feel the charm of math, practice and master math knowledge in entertainment.

| Game Examples


Calcrostic is exclusive to Caribou and is an upgraded version of Sudoku. The word "Calcrostic" is a creative combination of calculation and acrostic and can be understood as the art of calculation. Calcrostic took an innovative approach to sudoku, using letters instead of numbers, to figure out what numbers each letter represented based on the conditions of the equations in the title. The game level from the simple into difficult, such as 3*3 only horizontal and vertical line of the topic, relatively simple. But to complete the higher-level Calcrostic, you need to use a variety of algebraic basics such as equality and inequality, full division, and logical distinctions. In addition to providing the answers to the questions, the author also provides the optimal solution and detailed ideas for each question.

Chomp is a turn-based mathematical strategy game. This game is a two-player game, you can choose to play against friends, or against the computer. Each player takes turns taking candy from the board. When a candy is selected, the candy below and to the right of it is removed. The player who takes the last candy in the upper left corner loses.

The yellow slider in the game is "Cao Cao", we need to move the blue slider, and finally make the yellow slider move to the exit, so that "Cao Cao" successfully escape. Gameplay is also tricky, with the final title requiring around 150 moves to win.

Turtle Walk is a game where a Turtle can climb into a pond by using a certain number of "move forward," "turn left," and "turn right" modules provided by the title. The problems also range from easy to difficult, with younger students learning from simple instructions and older students developing optimal algorithmic thinking by limiting the number of programming blocks.
