The Mystery of the Lost Cookies 🍪

Introduction:

Today, we are going to embark on a delicious adventure in math! Imagine that we are at a birthday party, where a big plate of cookies has gone mysteriously missing—oh no! We need your help to solve the mystery of the lost cookies using division through repeat subtraction. Are you ready to become Cookie Detectives? 🕵️‍♂️🕵️‍♀️

---

Setting the Scene:

1. Story Setup:

   • Gather your students in a circle and describe the scene:

     “It was a bright sunny day, and the air was filled with the sweet smell of freshly baked cookies. Suddenly, during the party, the cookie plate started with 24 delicious cookies! But then, one by one, cookies began to disappear. Our job is to find out how many cookies are left after different kids take some!”

2. Interactive Activity:

   • Hand out a few artworks of cookies (drawing or printed images). Each student gets 1 cookie cut-out to represent the cookies taken.
   • Ask students to raise their cookie cut-outs to illustrate the idea of subtraction as they ‘take away’ cookies.

---

Engaging Question:

• Now, pose the following question to the class:

  “If 8 friends come to the party and each friend takes 1 cookie, how many cookies do we have left? Let’s use our secret code of repeat subtraction to find out!”

---

Guiding Into the Lesson:

• Encourage students to keep track of the number of cookies by repeatedly subtracting 1 from the total until all the cookies taken by friends are counted.

For example:

1. Start with 24 cookies.

2. Subtract 1 for each friend:

   • 24 - 1 = 23
   • 23 - 1 = 22
   • 22 - 1 = 21
   • (Continue until all 8 friends have taken their cookies).

3. Encourage students to keep track of their calculations on a whiteboard or paper.

Conclusion:

Now that we've solved the mystery of the missing cookies using repeat subtraction, we have not only saved the birthday party but also learned a fantastic way to use division!

Today, we’ll dive even deeper into how repeat subtraction can help us understand division better. Ready to solve more cookie mysteries? Let’s go! 🎉
