Teacher Hints
2014 April Smith
Introduce the project using this video about creating a candy
store: Its Sugar Candy Store.
When building the candy store, talk about what to scale means.
This scale works best with this project:
1 square = ft.2 total area is 195 ft.2 30 x 26If you are using a
different scale, make sure you complete task 1 before giving it to
your students to ensure that it graphs well with the dimensions of
the candy displays (too large of a scale may make the displays
really small too small of a scale may make the displays too
large.)
When students are working on the first part of task 1, have them
(in groups) measure the classroom door and how much space it takes
as it opens and closes. Record this information and go over it as a
class, then model how to draw the door using the scale. The
students can choose where their door goes on their own project, but
the measuring & scale drawing for this part needs to be shown
to them.
The checkout counter graphing should also be done as a class as
well. Modeling these graphing exercises (with student involvement
and input) will help students learn how to use the scale that they
will use themselves during Part 2.
Use the Teacher Appendixes to guide your instruction for each
part of the project.

Part 1: Build Your Candy Store
2014 April Smith
Ask Yourself: How much space does an open door take up? What
tools do I need to measure this in my classroom?
Label the door to enter your store. This is the symbol that
architects use to show a door.
Ask Yourself: How much space does a checkout counter take? Are
they all the same size? What tools do I need to measure this in my
classroom?
Place a checkout counter in your store. (Appendix A)
Brainstorm the other items you will need to put in your
store.

Part 4: Make Money!
2014 April Smith
Stores buy items like candy, then sell them for more money to
their customers. This is how the make profit. 1. Calculate the cost
of each item on your display to decide how much you are
paying for each. 2. Decide how much you are going to sell it
for, and how much profit you will
make. 3. Be careful not to overcharge, or people wont buy your
candy.

End of Project Checklist
2014 April Smith
Cut and paste your candy store onto construction paper under
your candy stores name.
Label the scale 1 square = sq. ft. on your graph paper.
Label the measurement of the length and width of your
floorplan.
Find the total area of your store using the formula A= L x W.
Write it under your graph paper.
Label the door to enter your store.
Place a checkout counter in your store.
Brainstorm the other items you will need to put in your
store.
Use the display dimensions to graph the displays in your store.
Add as many different types of candy displays as you can fit in
your store.
Count how many displays you have in your candy store.
Create a fraction for how many of your displays fit into each
category.
Cut & paste this data onto your construction paper.
Calculate the cost of each item on your display to decide how
much you are paying for each.

Enrichment: Grab Bags
2014 April Smith
Kids love buying candy grab bags because its a surprise what
candy they will find inside. The best thing about grab bags is that
there is a mix of different candy inside. Grab bags can make you a
lot of money in your candy store.
Choose 3 types of candy from your candy store. Fill out the
following table to show what candy you will include in your grab
bag. You will need 20 pieces total.
Type of Candy Fraction Ratio Decimal Percent
-
Appendix AAsk students to choose one of these checkout counters
(Show on projector, or you can have them do their own research if
they have student computers). Have them brainstorm how they can
estimate what their checkout counter will measure. They may want to
measure a large table in class, or put several tables together to
figure this out.

Appendix BAlthough many students may be comfortable with the
scale at this point in the project, most students will need a
little extra practice. Before you allow students to begin choosing
their candy and graphing the different size displays, practice on
scraps of Graph Paper.
Here is an example of how to show 1 square = sq. ft. and group
into whole pieces. Students who understand this concept can move on
to graphing the displays onto their candy store grid, while you
walk through all of the display measurements with the students who
are struggling. They can use their scraps of graph paper to help
them graph the same displays onto their candy store grid.
Instruction is very easy to differentiate with Project-Based
Learning!
