Interactive Paper Plate Fractions
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:
- Get two plates in two different colors.
- 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.
- 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.
- 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.
