Students will simplify two expressions, solve an equation to find x, and substitute their solution to find the perimeter and area of a square.
Page 1: A square with side lengths "7(x+5) - 2x - 15" and "2x - 10 + 3(2x - 10) - 2(x - 5)"
Page 2: Solve for x and explain your steps.
Page 3: Find the perimeter of the square and explain your steps
Page 4: Find the area of the square and explain your steps
* I used this mini-project to challenge only some of my 8th grade students who mastered solving equations with variables on both sides, but I can also see it being used as a good group activity for getting students to think critically.
