The 100th day of school is always a fun time to celebrate…and a great time to incorporate math concepts. Although this particular idea has been done with first graders, the activity can be adapted for other grade levels, as well.
- First, you’ll need 100 of 10 different small foods–like raisins, marshmallows, M&Ms, pretzel sticks, Life cereal, goldfish crackers, cheese crackers, Chex cereal, dried cranberries, Cheerios, chocolate chips, etc. (Just be mindful of any food allergies in your class as you select your items.)
- Divide the students into groups of about four. You can change this number of group members to accommodate your classroom; group size doesn’t make a difference for this activity.
- Now, have each child wash their hands.
- Next, place each of the food items in cups on each of the students’ table groups. They should have a cup of each item on their table. Just make sure that the cups have enough items for each student to count out 10 of each item. For example, for a group of four students, you would need a cup of 40 M&M’s for their table. No eating, yet, though… that will come later!
- Each student will then receive an empty egg carton (use only 10 holes; cut two off and discard).
- Students will then put 10 of each of the items (from the cups) into each of the egg carton holes. So, each student’s egg carton should contain 10 of each of the items in each of the ten holes. (hole 1= 10 raisins, hole 2= 10 marshmallows, hole 3= 10 pretzels, etc.)
- You could use this opportunity to teach 10×10=100, 10 groups of ten make 100, fractions (5/10 = 1/2, 2/10 = 1/5, etc.), or any other math concept that is appropriate for your class.
- When this is complete, everyone will bring their egg carton to a big bucket and dump it in. This will create a big mixture of all of the snack food items, making a yummy trail mix!
- Allow students to eat a small portion of the created mixture for their snack, then bag the rest in take-home baggies for students to take home for their families…so they can continue celebrating their 100th day at home!
