7th Math 3.6 Version B

Math - [Lesson 3.6]
Teacher: Mr. Kovalik (408) 314-1092
Objective and Summary:
SWBAT simplify expressions that include polynomial numerators by rewriting as separate fractions

**SYW in formative is optional for independent practice today**

1

You Try--Simplify the expression to standard form:

\frac{16x+24y-3}{4}

CFS:
#1: Accurately rewrites expression as separate fractions
#2: Simplifies to standard form

1

Standard--Write the following expression in standard form.

\frac{5n}{8}+\frac{n+3}{6}

CFS:
#1: Accurately rewrites expression with common denominators
#2: Simplifies to standard form

1

Level 2--Simplify the expression to standard form:

\frac{15x+20y-15-3x+y}{3}

CFS:
#1: Accurately rewrites expression as separate fractions
#2: Simplifies to standard form

MEDIUM PROBLEMS

1

All Equivalent?--Which of the following expressions are equivalent to the original expression below?
Select all that apply.

\frac{9y-6x+12}{3}

CFS:
#1: Accurately rewrites expression as separate fractions
#2: Simplifies to standard form

1

Standard Form--Simplify the expression to standard form:

\frac{12x-6y+39}{6}

CFS:
#1: Accurately rewrites expression as separate fractions
#2: Simplifies to standard form

1

Standard Form--Simplify the expression to standard form:

\frac{8f-3z+12f-9z+3}{4}

For this problem, you can show work in your notebook instead of in Formative. Remember to type your answer to check if it is correct.

CFS:
#1: Accurately rewrites expression as separate fractions
#2: Simplifies to standard form

SPICY--Try if you have time.

Analyze--Student McStudentson said, "I can simplify this expression by collecting like terms".
Which step of his work is the first to show a mistake or misconception? Explain what the mistake is.

Original Expression: \frac{9x+11y-6}{4}
Step 1: \frac{9x}{4}+\frac{11y}{4}-\frac{6}{4}
Step 2: \frac{20xy}{4}-\frac{6}{4}
Step 3: 5xy-1\frac{1}{2}

"There is a mistake in step... because..."

4

Standard Form--Simplify the expression to standard form:

\frac{12x-20y+7}{2}

You MUST SYW in Formative for full credit
