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).
