7th Math Unit 2 Day 16 - 11/29

Calculate--Evaluate the expression below (rewrite it as a single number).

For this problem only, please show your work on Formative.

5\times\frac{3}{2}\times3\times(-2)

CFS:

#1: Appropriately uses properties of operations to reorder expression

#2: Accurately evaluates expression

Calculate--Evaluate the expression.

\frac{3}{8}\times9\cdot(-16)

CFS:

#1: Appropriately uses properties of operations to reorder expression

#2: Accurately evaluates expression

Calculate--Evaluate the expression.

-1.3\times\frac{1}{2}\times(-4)\times10

CFS:

#1: Appropriately uses properties of operations to reorder expression

#2: Accurately evaluates expression

KCF is Back!--Evaluate the expression.

\frac{1}{2}\div(-\frac{1}{4})\times(-9)\times-(\frac{2}{3})

CFS:

#1: Appropriately uses properties of operations to reorder expression

#2: Accurately evaluates expression

Mix n Match--Don't calculate! Use the rules for signs to determine if these expressions will have positive or negative answers.

Efficiency--Use the commutative property of multiplication to evaluate the expression.

Hint: Try to multiply fractions so that they make whole numbers first.

-2(\frac{1}{3})\times4\times3\times\frac{1}{4}

CFS:

#1: Appropriately uses properties of operations to reorder expression

#2: Accurately evaluates expression

SPICY--Try if you have time.

(Remember that you can rewrite division as multiplication. Think KCF)

4\div\frac{2}{3}\times(-8)\times10\times(-\frac{3}{4})

CFS:

#1: Appropriately uses properties of operations to reorder expression

#2: Accurately evaluates expression

Evaluate the expression using properties of operations.

To get any credit, you MUST show your work on Formative.

10\times(-16)\times(\frac{-3}{2})\times\frac{1}{8}

CFS:

#1: Appropriately uses properties of operations to reorder expression

#2: Accurately evaluates expression
