Get ready for an interactive adventure on this worksheet! You'll be on a mission to identify eight sets of identical, equivalent expressions. It's not just a task, it's a thrilling matching activity! Your mission, should you choose to accept it, is to find pairs of equivalent expressions. Start by dissecting the expressions step by step: combine like terms, apply the distributive property, and factor out their greatest common factor (GCF). This mission, tailored for sixth and seventh graders, is a golden opportunity to master the use of properties of operations in dealing with algebraic expressions. Matching Clogs, the star of this mission, is an educational activity that makes learning about equivalent expressions a fun and interactive experience.

This worksheet reinforces key algebraic rules that can affect the appearance of expressions, such as:

- The distributive property (a(b+c)=ab+ac)

- The fact that multiplication and addition are commutative (a+b=b+a and ab=ba)

- The fact that multiplication and addition are associative ([a+b]+c=a+[b+c] and [ab]c=a[bc])

- The knowledge of the order of operations (PEMDAS/BODMAS).
