# When Factors Put on Their Dancing Shoes

What’s the narrative? That question, so fundamental to any novel, may not sound as relevant when applied to mathematics. Take, for example, the topic of factors: 1, 2, 4, and 8 are factors of eight; 3, 5, and 7 are not. Where is the inherent drama in these relationships? In most elementary mathematics curricula, there … Continue Reading ››

# “Data Games”—Getting the Math Right in Math Games

As a parent and math educator, I'm always on the lookout for high-quality, fun apps that help my sons and other young people develop their understanding of math. There are a large number of math games for mobile devices and PCs being churned out, and many articles being written in popular ed tech blogs and … Continue Reading ››

In a recent blog post, Karen Coe referred to Conrad Wolfram’s opinion that programming is to mathematics what composition is to English. I’ve taught programming and written a lot of Sketchpad code, and I appreciate Wolfram’s analogy. In English class, students read books, poems, short stories, essays, and articles—but to gain a deep appreciation for … Continue Reading ››

# The key to Everything Around You Is Right in Your Pocket

"You won't be carrying a calculator with you everywhere you go." A friend of mine recalled his math teacher telling him that. I'm sure we've all heard this or even have said it before ourselves. However, this particular retelling came over twitter, posted from an iPhone, that he keeps with him everywhere he goes. While it … Continue Reading ››

# When Factoring Gets Personal

As an author of Sketchpad activities, I like to think that I can pose good problems for students to solve. But as I visit elementary classrooms and watch students use Sketchpad, I realize that a large part of the enjoyment they derive from using our software comes from creating their own problems and sharing them … Continue Reading ››

# Touching the Math

Sketchpad has always been great for learning by doing. You can create a triangle and then manipulate the angles with your mouse and observe the results. There is something really primal, though, about using an iPad or a Smart Board, reaching in and grabbing the geometry with your bare hands. … Continue Reading ››

# What’s up with Key? A Response to Dan Meyer

The other week Dan Meyer sent out this tweet. While we appreciate the compliment (and the resulting increase in traffic), it's the first part of that sentence … Continue Reading ››

# Oh, the Fractions You’ll See!

A quick quiz: How many fractions are there? This may sound like an absurd question, but in the context of elementary mathematics curricula, it makes a lot of sense. Think about it: Children encounter fractions like 1/2, 3/4, and 2/6 all the time, but do they ever see 1/100, 31/90, or 499/500? Unlikely. No brave soul … Continue Reading ››

# Reflections, Multiple Representations, and Key

Today I'd like to share my personal story about Key Curriculum Press, a company I've experienced as a classroom teacher, as an editor, and now as a parent. For many weeks now, I've been trying to write a post about some of the dismal trends I see in education right now, but I keep getting bogged … Continue Reading ››
