Counting Money at Gary's Grocery Market
Day 3
“Percent or per cent?”
“Percent or per cent?”
Objective: Through the output of this lesson students will
hopefully understand the beginning
concepts of percentages by dividing the dollar into quarters. Students will also
be able to convert
between percentages, decimals and fractions. Along with the beginnings of
multiplying decimal
numbers together.
Tools: Fraction puzzle (25¢)
“Percent or per cent?” worksheet
Instruction: To begin students will receive the Fraction
puzzle using quarters. I will then ask the
children to show me multiple money values using the puzzles, and then
incorporating the
percentages of a dollar. Where as $0.50 is also 50% of a dollar. Through
explanation and hands
on activity, students will begin to grasp the one quarter is 25% of $1.00 and so
on. After this
comprehension I will then begin to demonstrate the association between percents,
decimal, and
fractions. (i.e.: 50% = .50 = 2/4) Students will come up to the board in order
to demonstrate
these associations, but limiting the boundaries with the use of quarters only.
In addition to
introducing percentages, I will cover the concepts and proper steps to multiply
a decimal value to
another decimal value. (i.e.: 5.00 x .25 = 1.25)
Assessment: Aside from the completion of the worksheet
“Percent or per cent?” Students will be
demonstrating there understanding of this concept by using the Fraction puzzle
manipulative in
order to display the fraction, decimal (dollar notation), and percentage of the
whole.

Day 4
“SALES, SALES,
SALES…But what’s my final
price?”
“Sales, Sales, Sales…but what’s my final price?”
Objective: The overall goal within this lesson will be for
students to be able to find the final sale
price after applying a percentage off. Through this demonstration students will
be reviewing
their skills with subtracting and multiplying decimals, while also gaining the
proper steps in
order to calculate such a figure.
Tools: “Sales, Sales, Sales…but what’s my final price?”
worksheet
Instruction: Within this lesson I will once again review almost everything that
has been learned
in the prior lessons. We will review how to convert and recognize the
association between
percents and decimals, multiplying decimals together, and finally subtracting
decimals from one
another. Aside from basic review and rehearsal of already taught skills, it will
be necessary for
me to introduce an organized procedure in order for students to be able to find
the actual price of
an item after it has been put on sale. I will present the following steps to my
students:
-convert percentage to a decimal value (i.e.: 25% = .25)
-multiply your found decimal value by your original value (i.e.: $1.00 x .25 =
.25)
-once this value is found, take your product away from your original sale price
to find
your final sale price (i.e.: $1.00 - .25 = $0.75)
Assessment: In order to best assess a student’s
performance with this concept will be to have
them complete the worksheet entitled “Sales, Sales, Sales…but what’s my final
price?”
“Sales, Sales, Sales…but what’s my final price?”

1. 50% of $2.00
2. 25% of $5.00
3. 75% of $4.00
4. 25% of $3.00
5. 100% of $5.75
6. 75% of $6.00
Complete the following subtraction problems.
7. $3.56 - $2.34 = _____ 8. $5.00 - $2.25 = _____ 9. $7.80 - $2.80 = ____

Day 5
“A Trip to Gary’s Grocery
Market”
“A Trip to Gary’s Grocery Market”
Objective: The objective of this day will be for students
to applying all subject matters learned
during this unit. Not only will they be assessed with paper and pencil, but
through peer
assistance and team efforts to help and encourage others to excel and present
their abilities to the
rest of the class.
Tools: Penny Pincher Coupon Game
“A Trip to Gary’s Grocery Market” worksheet
Instruction: Students will be split up into 5 groups at
the beginning of this lesson period. At this
point I will pass out envelopes filled with a variety of coupons. I will explain
to the students that
every group has a different variety of coupons in which they will apply to the
grocery list that I
will provide for them. There will also be cards with total sale price discounts
in which they have
to apply to the total sale price. Upon receiving the grocery list they will
begin to total up the sale
prices and apply all discounts and coupons. While making sure students know it
is not a race but
more of a time for peer sharing and group analysis; when enough time has passed
students will
then present their methods making sure to have each student to present a portion
of the exercise.
After completion of presentation I will adjust to reviewing any specific skills
needed to complete
the worksheet.
Assessment: Not only will the students be given the
worksheet of “A Trip to Gary’s Grocery
Market,” but they will be assessed aurally by presenting the steps they took in
which to complete
the Penny Pincher game.
Summary
Throughout this process I have found that creating a unit
of lessons, is quite a daunting
task. Not only do you have to decide what topic to cover, but you have to make
sure that it
applies to the PASS standards, along with creating manipulatives and finding
resources or
generating your own worksheets in order to assess the students. Though I
consider myself a
creative person, it is very easy to find ones self in a stand still trying to
think of something
different and new. Aside from those, one must evaluate the abilities of the
class and adjust
accordingly if need be; without being in a classroom you find yourself second
guessing the
lessons and skills in which you intend to teach through that day. Though you
feel capable
enough and understand the topic that you want to present, you must be able to
retrograde back to
the most basic of levels to ensure the comprehension of every student. From this
my already
esteemed respect for educators of the world has grown even more just from a unit
only covering
a theoretical week.
