The Four Fours project is a collaborative activity that stresses problem solving and critical thinking as applied to order of operations problems.

The objective of this group activity is to use your knowledge of order of operations and a combination of four fours to create all the numbers from 1 to 40 (1 to 30 if you are in a group of 3). The four fours must be mathematically manipulated to create your desired number. For example, we can use four fours, grouping symbols, and three operations to create the number 8.

Ex. (4 + 4) + 4 x 4 = 24
