Math - [Lesson 2.8]

Teacher: Mr. Kovalik (408) 314-1092

Objective and Summary:

SWBAT use properties of operations to add and subtract rational numbers efficiently

For all problems today, I suggest calculating on your notebook first, then copying your work into Formative afterward.

null

Evaluate the following expression.
-\frac{1}{3}+2\frac{8}{9}+1\frac{1}{3}
CFS:
#1: Appropriately rewrites expression using properties of operations
#2: Accurately evaluates expressions

Evaluate the following expression.
1.25-3+2.50-(-0.25)
CFS:
#1: Appropriately uses properties of operations to rewrite expression
#2: Accurately evaluates expression

Remember that we can split up mixed numbers. The whole number and fraction will go in the same direction on the number line.

null

Evaluate the following expression.
\frac{1}{5}-2\frac{1}{4}-3\frac{1}{5}
CFS:
#1: Appropriately rewrites expression using properties of operations
#2: Accurately evaluates expressions

MEDIUM Problems

Evaluate the following expression.
20.3-(-1.5)+0.5-0.3
CFS:
#1: Appropriately uses properties of operations to rewrite expression
#2: Accurately evaluates expression

Evaluate the following expression.
-9\frac{1}{10}-(-6\frac{1}{2})-1\frac{9}{10}
CFS:
#1: Appropriately rewrites expression using properties of operations
#2: Accurately evaluates expressions

Evaluate the following expression.
1.3+7-4+2.7
CFS:
#1: Appropriately uses properties of operations to rewrite expression
#2: Accurately evaluates expression

SPICY--Try if you have time.
SYW in formative is optional
Evaluate the following expression.
2\frac{1}{3}+\frac{1}{2}+3\frac{1}{5}-\frac{2}{4}-\frac{1}{3}

null

Evaluate the expression.
-5\frac{5}{7}+8-3\frac{2}{7}
You must SYW in formative to receive full credit
CFS:
#1: Appropriately rewrites expression using properties of operations
#2: Accurately evaluates expressions

Awesome!

You can...

1) Study/review for your quiz by looking through notes 2.1 through 2.8

2) Practice for your quiz by doing any recommended (starred) IXL skills, expecially for rational numbers
