## Interactive Paper Plate Fractions

Cynthia Hockman-Chupp

While preparing to teach a fifth grade lesson using clock fractions, I ran across a photo on Pinterest that inspired me to try a little paper plate math.

How to Assemble:

1. Get two plates in two different colors.
2. Mark the center and make one straight cut from the edge to the center point.  I stacked the plates on top of each other and cut them at the same time.
3. Slide the plates together so that the cuts match up in the middle and you’re able to rotate one plate to reveal the other.
4. Add incremental numbers to one of the plates.  For this example, I numbered one plate to resemble a clock.

Model with Many Uses:
Use these handy little visuals in a variety of ways:

• Modeling fractions – Ask students to show you 1/12, 2/3, or 1/4 of an hour.
• Adding fractions – Ask students to spin the model to show 1/2 + 1/4 and other addition expressions. A pair of students might even hold two plates to add fractions with a total greater than 1.
• Subtracting fractions – Students can model 9/12 – 1/3 and other subtraction problems.
• Fraction stories – Write and demonstrate fraction stories on the interactive model.
• Homework – Send this interactive visual model home.
