Math Lesson
for Cookie Day
Objective:
The students will create fact
families using manipulatives.

Materials

Procedure

Pass
out the cookie shapes (2 per student) and a handful of
chocolate chips to every student.

Introduce/review
fact families depending on the students'
knowledge. Write 3 numbers on the board which
comprise a fact family, i.e. 2,3,5. The students
may use their chocolate chips and cookie shapes to
demonstrate 2 addition and 2 subtraction equations
using those numbers. For example, they will
place 2 chocolate chips on one cookie shape and 3 on
the other to make the equation 2+3=5. Then
instruct the students to have their cookie shapes
switch places to create the sentence 3+2=5. For
subtraction have the students pull one shape away for
the first equation and the opposite shape away for the
second.

Pass
out the Fact
Family Worksheet for the students to complete as a
group or individually, depending on their skill level.

Other
Lesson Ideas

Since
cookies are often baked in dozens, have a lesson on
the number 12. Give each student a Dozen
Cookies Worksheet to cut out and use to explore
the number 12. Is 12 an even or odd number?
How many groups of 2, 3, or 4 are in 12? How
many different number sentences can be written to
equal the number 12?

Read
the book The Doorbell Rang by Pat Hutchins and
have a lesson on dividing.

Do
any of the math activities at The
Oreo Project web site.

Show
the students a cookie sheet and cookie, such as an
Oreo. Have the students estimate how many
cookies will fit on the cookie sheet. Place the
cookies on the sheet and see how close the estimates
are. Do the same activity with how many cookies
fit into a given cookie jar.

Have
the students graph their favorite type of cookie.
