Fraction Toast: The Best Activity to Introduce Fractions


Do you need a quick activity that will help your students understand fractions? 
This year one of our most successful (and best tasting) activities was Fraction Toast.
This activity only takes one hour and is perfect for students from 4th grade through middle school.



FRACTION TOAST

Numerator equal to the number of pieces of toast with jelly, avocado, peanut butter, etc.
Denominator equal to the number of pieces that the toast is cut into.
Our picture shows two-thirds.

Materials:  a toaster, bread, spreads (peanut butter, avocado, jelly), butter knife, paper towels, paper and pencil, camera

Method:
  1. Decide on a few fractions to visualize.  Choose denominators that are easy to cut out!
  2. Toast the bread.
  3. Cut the bread into pieces equal to the denominator.
  4. Apply spread to the number of pieces equal to the numerator.
  5. Make a label using paper and pencil and place the label near the fraction toast.
  6. Photograph your edible work of math-art.
  7. Eat the Fraction Toast.
 This activity was designed by Limelight Education in San Diego!
