A fun way in which students can choose four digits, 0-9, and create a number problem in which the answer is 24. They may use any of the 4 operations to solve the problem, however, each number may only be used once, no limit on operations. This is a great activity to supplement lessons on order of operations, math properties, and critical thinking. The cards should promote more than one solution with the 4 numbers to reach an answer of 24.
This is best printed on cardstock, and may be given as an engaging homework assignment. These can then be cut up, shuffled, and redistributed to small groups of students to play 24! Can they solve their classmates problems?
