Fractions to Decimals (Objective 1):

SWBAT convert fractions to decimals

To change a fraction into a decimal, we must divide the fraction.

Example 1:

What decimal is the same as 3/8?

Helpful Hint: “Top dog gets the house”

Whiteboard CFU

What decimal is equal to 5/7? Round to the nearest hundredths place.

Fist to 5: Check for Understanding

On a scale of 0-5:▪ 5= Currently a master at this objective

▪ 0= I don’t even know where to start

▪ Any number in between

Rate your current level of understanding of Objective 1 on the line next to your written objective on the first page of your notes.

Fractions to Percent (Objective 2) :SWBAT convert fractions to percent using multiple methods :

We can convert fractions into percent using two methods.

Select the method that is most comfortable for you! But you need to be familiar with both!

Method 1

▪ Convert fraction to a decimal

▪ MULTIPLY that decimal by 100, which means you MOVE the decimal over two spaces to the right.

Example:

2 =

7

Decimal to Percent=

Method 2

Example: Convert 4/5 into a percent.Step 1: Set the fraction equal to

“x over 100”

Step 2: Cross-multiply the proportion, then solve for x. Whatever x equals will be your percent.

Whiteboard CFU:

1. Change 8/15 into a percent. Round to the nearest whole number.

(choose either method 1 or method 2)

Whiteboard CFU

Change 17/50 into a percent

(use different method then the one used before)

Fist to 5: Check for Understanding

On a scale of 0-5:▪ 5= Currently a master at this objective

▪ 0= I don’t even know where to start

▪ Any number in between

Rate your current level of understanding of Objective 2 on the line next to your written objective on the first page of your notes.

Percent to Decimals and Fractions (Objective 3):SWBAT convert percent to decimals and fractions

Example:

Convert 45% into a fraction and a decimal. Simplify fraction.

Percent Fraction Decimal

Whiteboard CFU

Convert 325% into a FRACTION and DECIMAL

Percent Fraction Decimal

Whiteboard CFU

▪ Convert 36% into a FRACTION and DECIMAL

Percent Fraction Decimal

Fist to 5: Check for Understanding

On a scale of 0-5:▪ 5= Currently a master at this objective

▪ 0= I don’t even know where to start

▪ Any number in between

Collaborative Groups:

▪ Team Captain (2)

▪ CFU Leader

▪ Materials Manager

How will you effectively and fully execute your role during your collaborative group time?

Tasks:1) Team Captain- Go over “Criteria for Success” with group.

2) Materials Manager- “Group Practice” for Group.

3) Complete EVENS together…leave no man or woman behind. If done early, work on ODDS.

4) CFU Leader- Compare answers to answer key and troubleshoot wrong answers.

5) Individually- Complete “Formative Assessment/Reflection”

6) Begin Independent Practice.

Lesson 6: Formative Quiz/Reflection

1) Write to an absent student and explain to them how to complete the following. Be clear in the steps and provide an example to help in your explanations:

a) convert fractions to decimals

b) convert fractions to percent using method 1 and method 2.

c) convert percent to decimals and fractions.

2) Reflection:a) What did we learn today ? b) So What ? (relevancy, importance, usefulness) c) Now What? (how does this fit into what we are learning, does it

affect our thinking, can we predict where we are going) d) Questions I still have are…(provide at least one question of what

will help you master the objectives).
