Multiplication: Lost in Translation?

A recent task I developed used visual models of multiplication involving a unit fraction. Can you match visual models with the expressions ⅓ x 12, ⅓ of 12 or 12 x ⅓? Who would have guessed that creating this task would send me on a hunt through time and continents for the first definitions of multiplication, multiplier, and multiplicand?

Why is Fraction Arithmetic So Hard AND Important!

I recently stumbled upon the work of Robert Siegler, a professor of cognitive psychology at Carnegie Mellon University who is working with several colleagues to determine why fraction arithmetic is so difficult.   Of course, all the researchers he’s worked with should also be acknowledged (see below), but this is one of those times you read […]

A Fraction-Algebra Sandwich

Peck and Matassa (2016) recently published a research paper that reinforced why fraction division and multiplication is such an important topic for children to master. We often hear that understanding fractions is a gateway to learning algebra, and these authors offered some pretty compelling reasons why that’s the case. Before we get to the study, […]

Teaching Fractions with Newton’s Nemesis

Today, I uploaded a new video on YouTube that condenses all the research behind my math mystery comic book series, Newton’s Nemesis. It’s fast paced and 7-minutes long. Every time I need to learn something (like my recent adventure changing a burnt out headlight in my car), I search for a video on YouTube. That […]

Math & The Characters: Theo’s Sister Leah

One of the most common reasons children struggle when learning fraction division is because they haven’t fully developed their understanding of division with whole numbers.  Children need to understand different interpretations of division and have the opportunity to make connections between whole number division and fraction division.  I created Theo’s younger sister Leah to help […]
