Metric Cookies
Designed
by:
David K. Blackwell, Gibbes Middle School
GRADE
LEVEL: 6th
SUBJECT(S):
Math
1)
CORE CURRICULUM OBJECTIVE(S):
Compute
(+, -, x) and convert (smaller/larger units within the
customary and metric systems).
(6ME1-3)
[V.B.1]
[V.B.2]
RESTATEMENT:
The
student will convert customary units of measurement to
metric units of measurement using multiplication.
2)
OVERVIEW:
This
activity can be used as enrichment or as an
application lesson after students have learned how to
convert from customary to metric units of measurement.
Students will work in pairs to convert a chocolate
chip cookie recipe from customary to metric units so
that a pen pal from England can use it. Then they will
be able to choose a recipe of their own to convert
from customary to metric units. They will put the
converted recipe on a 12" x 18" poster board
"RECIPE CARD." They will decorate it and
display the cards in the classroom or in the media
center. This card, along with a friendly letter to a
pen pal in another country that uses the metric
system, will be the assessment.
3)
FOCUS/ESSENTIAL QUESTION(S):
1.
A pen pal has asked you to send a favorite cookie
recipe, the only problem is that your recipe is in
customary units of measurement. How do you change the
cookie recipe to metric units of measurement?
2.
Do we use Fahrenheit or Celsius to talk about
temperature? What is used in other countries.

"Using Your Melon for Math" is an excellent
extension lesson using a recipe to practice
multiplication and division of fractions.
www.nytimes.com/learning/general/featured_articles/990715Cthursday.html
This
is the recipe needed to complete "Using Your
Melon for Math". It could be used as an
extension
of the "Metric Cookies Lesson". Students
could convert the customary units of
measurement to metric units.

If you want to provide your students with a
temperature conversion chart, this is a good site.
6)
ASSESSMENT: The culminating assessment will
consist of a friendly letter written to a pen pal in
another country that uses the metric system and a
completed recipe card converted from customary to
metric units of measurement.

INSTRUCTIONAL ACTIVITIES:
DAY
ONE
1.
Begin the lesson with the statement of the objective(s).
2.
Continue by using the focus questions. Let the
students volunteer to answer these.
3.
Continue the lesson by reviewing the metric units of
measurement for liquids and solids (This material can
be obtained from one of the sites listed in the
resources.)
4.
Divide the class into pairs or groups of three.
ACTIVITY
1
5.
Pass out Attachment 1 and Attachment 2 to each
student.
6.
Let the students complete the activity individually.
You should monitor the activity, offering assistance
when you see that a student needs help.
7.
Once the students have completed the activity, have
them share their completed worksheet with their
partner or group.
ACTIVITY
2
8.
Next, have the students get out a piece of notebook
and a cookbook. The students could bring in a cookbook
for extra credit points on the final assessment. The
media center may have copies of recipe books from
around the world that you can display in the room.
9.
The students should work individually and find a
recipe of something they like. They should copy the
recipe on their notebook paper.
10.
Next, they should convert the units of measurement to
metric units of measurement.
11.
After they finish it, they should ask their partner(s)
to look at the converted recipe. Once they do this,
check their work before they transfer the recipe to
the poster board.
DAY
TWO
12.
ASSESSMENT - When all calculations are correct, the
students should transfer the recipe on the 12" x
18" piece of poster board. They should decorate
it with drawings or pictures.
13.
ASSESSMENT - Each student should write a friendly
letter telling their pen pal about the recipes that
they converted for them. They should include how they
converted the measurements. Both the recipe card and
friendly letter should be displayed in an area in the
school where others can enjoy the students' work.
EXTENSION
ACTIVITY:
Students
can make INSTANT RUSSIAN TEA or the PARTY MIX with
ingredients listed in the recipe below. Before they
make the recipe they could convert the recipe to
metric measurements and actually use metric measuring
tools to put the ingredients together. This recipe
could be shared with their parents.
|
INSTANT
RUSSIAN TEA
1
(9 OZ) jar of Orange Tang
1/2 Cup of Sugar
1/2 Cup of Instant Tea with Lemon
1/2 Tablespoon of Cloves
1 Tablespoon of Cinnamon
1 Package of Lemon Kool-Aid
Mix
all dry ingredients. Use 2 tablespoons of the
mixture in 1 cup of hot water and serve. The
Lemon Kool-Aid may be omitted if desired. |
| PARTY
MIX

cereal, pretzels, and nuts until they are will
covered with the butter mixture. Bake 1 hour
at 250 degrees Fahrenheit. Stir it every
fifteen minutes. |
The
class could be divided up into groups and each group
decide on a recipe to make. They could then have a
MATH PARTY and invite the parents to view their work
and enjoy the foods.

CONVERTING
FROM FAHRENHEIT TO CELSIUS TEMPERATURE.
The formula for converting from Fahrenheit to Celsius
is as follows:
°C = (°F -
32) x 5/9
Use
this formula to change the oven temperature of 350°F
to the correct °
Celsius. Show your work below.

Using
a conversion chart or metric calculator, change the
following recipe from customary units of measurement
to metric units of measurement.

My
Favorite Chocolate Chip Cookies |
| Customary |
Metric |
| 1
Cup butter or margarine (softened) |
|
| 1
Cup firmly packed brown sugar |
|
| 1
cup granulated sugar |
|
| eggs
beated |
|
| 1
teaspoon vanilla extract |
|
| 2
cups all-purpose flour |
|
| 1
teaspoon baking soda |
|
| 1/2
teaspoon salt |
|
| 3
cups rolled oats (quick or old fashioned,
uncooked) |
|
| 12
ounces semi-sweet chocolate pieces |
|
| 1
cup chopped pecans or walnuts |
|
Heat
oven to moderate at 350° Fahrenheit. Beat butter and
sugars until creamy. Blend in eggs and vanilla. Sift
together flour, soda and salt. Add to creamed mixture,
beating well. Stir in oats, chocolate pieces and nuts.
Drop by teaspoonfuls onto ungreased cookie sheets.
Bake about 12 minutes. This recipe makes more cookies
than any recipe I've ever used. I also converted it to
a good oatmeal-raisin cookie by deleting the chocolate
chips and adding 1 cup raisins and 1/2 cup coconut.
This makes a soft chewy cookie.
1.
What would the temperature be instead of 350°
Fahrenheit?
2.
Convert the 1 cup raisins and 1/2 cup coconut to
metric measurement.
__________
raisins ________
coconut
3.
For extra credit do research to find out the
English terms for any of the ingredients. You can use
