Your students are going to enjoy generating equivalent expressions in this common core focused cut and paste activity. They will be required to use properties of math, combining like terms, and factoring to find three expressions that all have the same value. Once done, they will evaluate the expressions given the value of x to see that they all equal the same. This cut n' paste puzzle will make it both fun and interesting. Trust me, this activity will have your kids focused and they will also get quite a chuckle out of the riddle answer. Enjoy!

The Common Core standards addressed in this activity are 6.EE.A.3 and 6.EE.A.4, but it is appropriate for higher middle school levels as well.
Apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3 (2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y.
Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them). For example, the expressions y + y + y and 3y are equivalent because they name the same number regardless of which number y stands for.
