Equivalent Expressions & The Commutative Property | 6.EE.A.4

The video tutorial explains how to write an equivalent variable expression by identifying variable and constant terms and using the commutative property. The instructor presents a problem involving the expression '5M add 7' and evaluates four answer choices to find the equivalent expression. The tutorial emphasizes the importance of understanding variable and constant terms, simplifying expressions, and applying the commutative property to solve the problem. The correct answer is identified by rearranging terms using the commutative property.

What is a variable term in the expression 5M + 7?

• 5

• 5M

• 7

• M

Why can't the terms 5M and 7 be added together?

• They are already simplified.

• They are not like terms.

• They are both variables.

• They are both constants.

Which of the following is NOT an equivalent expression to 5M + 7?

• 7 + 5M

• 5M + 7

• 12M

• 7M + 5

How does the commutative property help in finding equivalent expressions?

• It allows changing the order of terms.

• It allows changing the value of constants.

• It allows multiplying terms.

• It allows adding different variables.

What is the correct equivalent expression for 5M + 7 using the commutative property?

• 7M + 5

• 12M

• 5M + 7

• 7 + 5M
