Challenge 24

Challenge 24 is a mathematics game in which competitors use multiplication, addition, subtraction, and division in various combinations to manipulate four numbers on a card to equal 24. The Trumbull County Educational Service Center and the Tribune Chronicle hold their annual Challenge 24 Tournament in the Fall.

Students participate in four divisions: grade 4 in Division 1, grade 5 in Division 2, grade 6 in Division 3, and grades 7 and 8 in Division 4.
