Objective: Students will be able to convert between decimals and percents.
Key Points
List 2-3 key points or skills that students should be able to know or do by the end of your 5 minute mini-lesson:

"Percent" means "out of 100" so 47% is the same as 47/100 or "47 out of 100".
To convert a decimal to a percent, represent it as a fraction first. When the denominator is 100, then it’s “out of
100” and can be converted to a percent.
To convert a percent to a decimal, convert to a fraction out of 100 first. Then, use place value reasoning to convert
to a decimal.
Plan Your Lesson
What materials will you need to prepare ahead of time?
I will prepare a chart to be filled in as we convert fractions, decimals and percents. The chart will have a decimal filled in
and then ask for them to fill in the equivalent percent. I will also have a student handout with practice problems.
What you are doing
Opening – Introduce the objective and the purpose of your lesson.
Yesterday we learned how to read decimals based on their place values.
30 sec. – 1 min.
Who can raise their hand and remind me – how would we read “.29”?
Expected answer: We would say 29 hundredths.
What students are
doing
How will students
learn the objective?
Students will be
listening carefully
and responding to
questions.
Why?
Expected answer: Because the decimal goes to the hundredths place, so it represents 29
hundredths.
Good job! That’s going to come in handy today. We are going to be converting decimals to
percent and percent to decimals.
One thing that’s going to help us figure out how to convert between decimals and percent is
one simple fact – the word “percent” actually means “out of 100”.
3–4
minutes
Using that fact and what we learned yesterday about how to read decimals, we will be able to
do these conversions!
Mini-lesson – Explain your key points or skills to students and then have them practice with the
information.
How will students
practice the key
points or skills that
they’ve learned?
Let’s start with an example – 47%. We are going to turn this percent into a decimal.
When I say 3, everyone remind me again, what does “percent” mean? 1-2-3
Expected Answer: “Out of 100”.
Good, now how would I represent “47 out of 100” as a fraction?
Expected answer 47/100.
Students will be
taking notes on
their worksheets,
and then they will
practice converting
decimals and
percents on their
own.
Now I see 47/100, and I can think to myself “that says 47 out of 100 or it says “forty-seven
hundredths”.
How would I would I write the decimal “forty-seven hundredths”?
Expected answer: .47
Let’s do an example the other way around… How would I turn .07 into a percent? Well, let’s think
about it as a fraction. What is “seven hundredths” as a fraction?
Expected answer: 7/100.
Oh, and what’s the other word that means “out of 100”? Tell me on 3. 1-2-3
Expected answer: “Percent”
So, what’s another way to think about 7 out of 100? 7%!
Notes
To convert between decimals and percent – think about how to represent the value as a fraction,
and then use the fraction to determine what the decimal or percent is.
Student Independent Work
Take 1 minute on your own to do numbers 1 and 2 on your worksheet.
30 sec. – 1 min.
Closing – Sum up your lesson and check if students have mastered the objective.
Cold call –
#1 What is 35% as a decimal? How did you find your answer?
#2 What is .29 as a percent? How did you find your answer?
Good, today we learned that you can use fractions to convert between percent and decimals.
Right now, everyone should spend 30 seconds doing #3 and #4. I’m going to come around to
see how you’re doing and then I will collect your worksheets when you’re done and check them.
What will students
do to show that
they’ve mastered
the objective?
Students will
volunteer answers
and explain how
they found their
answers. Then, they
will do a problem
on their own so I
can check for
understanding.
