Fraction Talks

Fraction talks developed as a way to use the Number Talk routine to target fractions. A growing body of fraction talks are available at fractiontalks.com.

I’ve created a writeup below for how to use fraction talks, as well as a collection here which are ideal for introducing fraction talks to students early in their understanding of fractions, and then continuing in slowly increasing levels of difficulty.

    After processing whether or not if the green shaded region of the first example is 3/4 or 3/8, an interesting follow-up question to pose is “What is 3/4 the correct answer to?” [3/4 of a 1/2 piece or 3/4 x 1/2]. Consider then posing the question to the class, “Is 3/4 of a half piece the same as having 3/8 of the whole piece?” [Write out the equation, 3/4 x 1/2 = 1/8 x 1] “Is that true or false?” I have been experimenting adding the “x 1” to help students – and the adults with whom I do p.d. – that one way to envision multiplication of fractions is through the re-unitizing of the first mathematical expression [3/4 of a 1/2 piece or 3/4 x 1/2] to the whole unit [x 1]. The area shaded green to the unit of one-half is compared [=] to the unit of the whole [x 1]. The eye just shifts from unitizing it from the one unit to the other. The area does not change; just the unit referent. This work grows out of my using some materials from Susan Lamon (2015).

    Hi, I have a grade 6 class. They are converting fractions to percentages and decimals. Do you think this could be used for this purpose? I love the idea. It’s simple and interactive. You say in the description that this is grade 4-9. How would you modify this for older grades. (grade 6 specifically), thank you!

      You can pretty much use them as is at a range of grades. The same image will give rise to various conversations depending on the depth of what kinds can see.
