### Description

Have students express the numbers 1 through 10 by combining 4’s with any mathematical operation. They must make sure they use the order of operations correctly and use parentheses when needed to show exceptions; for example, 5 = (4 x 4 + 4) / 4.

Encourage students to find a variety of solutions. Have them explain why their order of operation works.
