CFS:
#1: Accurately identifies like terms
#2: Accurately rewrites expression in standard form by collecting like terms

1

Collect 2--Rewrite the following expression by collecting like terms.

SPICY--Try if you have time.

Smartest Brother?--Babel says that -4(7x)+12y-3 is equivalent to -28x+9y.

Do you agree with him? Explain why or why not.

"I (agree / disagree) with Babel because..."

CFS:
#1: Accurately identifies like terms
#2: Accurately rewrites expression in standard form by collecting like terms

SPICY--Try if you have time.

Now with Fractions!--Rewrite the expression by combining like terms. The rules are the same even if you have fractions for coefficients.

\frac{1}{4}x+7y+\frac{1}{2}x-10y

CFS:
#1: Accurately identifies like terms
#2: Accurately rewrites expression in standard form by collecting like terms

4

Equivalent--Rewrite the following expression by collecting like terms.
Show each step of your work for full credit.

3(3a)+2(-6b)+a

CFS:
#1: Accurately identifies like terms
#2: Accurately rewrites expression in standard form by collecting like terms

Good job! This is a short lesson so push yourself ahead on the following:

1) Combine like terms on IXL with visuals (Search code: PCU)
2) Combine like terms on IXL (Search code: JJG)
