What Is Multiplication, Anyway?

Posted on December 12, 2020December 10, 2020 by Denise Gaskins

At some point during the process of teaching multiplication to our children, we really need to come to terms with this question:

What IS multiplication?

Did your device hide the video? Find it on YouTube here.

“What’s my answer? It’s not one that society’s going to like. Because society expects — demands, even — that mathematics be concrete, real-world, absolute, having definitive answers.

I can’t give a definitive answer.

Multiplication manifests itself in different ways. So maybe the word ‘is’ there is just too absolute. And it’s actually at odds with what mathematicians do.

Mathematicians do attend to real-world, practical scenarios — by stepping away from them, looking at a bigger picture.”

—James Tanton, What is Multiplication?

What Are Mixed Numbers?

Posted on December 3, 2020December 3, 2020 by Denise Gaskins

I just discovered a fascinating fact: In some places in the world, mixed numbers apparently don’t exist.

So that made me curious about my blog readers:

Did you learn about mixed numbers in school?
Do you ever use mixed numbers in daily life?
Are your children learning to work with them?

And if you DO know mixed numbers, can you simplify this mess:

[If you enjoy dry math humor, the answer is worth the work.]

Exciting New Homeschool Math Program

Posted on November 18, 2020November 17, 2020 by Denise Gaskins

Homeschooling friends, check out this new homeschool math program that’s fun, rigorous, and engaging — a delightful, hands-on course that helps parents (and their children) understand math.

Introduction to Cuisenaire Rod Structures Course

I had the privilege of previewing this class as Sonya and Lacy put it together. I highly recommend it to anyone who struggles with math, or who wants to take a non-traditional approach.

By focusing on making sense of number relationships, and by teaching algebra before arithmetic, this course provides a stress-free path to rich mathematical mastery.

And for all they provide, including weekly live workshops and a slew of printable math journal pages that prompt deep thinking, the price is a steal!
