## Book Review: The Absolute Value of Mike (and Dyscalculia)

When I saw this book at the library, I was drawn directly to it. Why? For one thing, my post on dyscalculia and teaching math is one of my most popular posts ever. For another, I am always seeking good children’s books with mathematics themes to enhance my teaching or recommend to students. Finally, given […]

## Video: MSNBC Report on Singapore Math Model Drawing

MSNBC ran a piece on May 3 about third-grade students learning math using Singapore Math. This report outlines the importance of model drawing for problem solving, and of parent understanding to be on board with it.

## Video: Our NaNoWriMo YWP anthology is famous!

Imagine my delight today to find out from one of my young writers that my students’ anthology from last year had been featured on the NaNoWriMo Young Writers’ Program blog in late October.

## Video: Adding and Subtracting Algebraic Fractions

I came across this video from a Singapore tutor in my browsing today. It explains how to simplify an algebraic fraction problem. Interestingly, I solved a similar problem with my one of my algebra students last week. I like how this blogger breaks the steps down, but I would like her to explain more why […]
