Cookie Day

Math Lesson
for Cookie Day

Objective:
The students will create fact families using manipulatives.



Materials

 

Procedure

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

  2. 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.

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

 

Other Lesson Ideas

  1. 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?

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

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

  4. 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.

  5. Have the students graph their favorite type of cookie.
