  1. Cookies! A book on fractions By Natalie Machaud

  2. Annie loves to bake! Today she has decided to bake a batch of 36 cookies.

  3. Annie’s mom gives 1/3 of the 36 cookies to their neighbor. 36 divided by 3 equals 12. Annie’s mom gives 12 cookies to the neighbor.

  4. Now Annie has 24 cookies. Her brother eats 1/8 of them. 24 divided by 8 equals 3. Her brother eats 3 cookies.

  5. Now Annie has 21 cookies. Two of Annie’s friends come over. Together they eat 1/3 of the cookies. 21 divided by 3 equals 7. Together they eat 7 cookies.

  6. Now Annie has 14 cookies. She decides to take 1/2 of them to her teacher tomorrow. 14 divided by 2 equals 7. Annie gives 7 cookies to her teacher.

  7. Now Annie has 7 cookies. After dinner that evening, Annie eats 1/7 of the cookies. 7 divided by 7 equals 1. Annie eats 1 cookie.

  8. Now Annie has 6 cookies. Her dad looks hungry. She gives him 1/3 of the cookies. 6 divided by 3 equals 2. She gives him 2 cookies.

  9. Now Annie has 4 cookies. She decides to save the last 4 to give to her grandparents when she sees them tomorrow.

  10. (4 divided by 2) If each of her grandparents eats 1/2 of the 4 cookies, they will each eat 2 cookies.

  11. Now Annie is out of cookies! I wonder who she will give all of her cookies to the next time she decides to bake a batch!
