Nat Banting created the Fraction Talks website, which has a huge collection of images to inspire discussion and exploration, as well as suggestions for using this routine in your class. 

A Fraction Talk is a discussion-rich routine that invites multiple ways of identifying fractions. They are similar to number talks, but instead of drawing out strategies through mental calculations, students evaluate images like this one and ask questions like,

“What fraction of this figure is yellow?”

or

What fraction of this shape is blue? How do you know?

You can also use Fraction Talks to investigate other math concepts.

For example:

If the area of this shape is 32 square units, what is the area of the of the blue sections?
