Digging Through the Archive
Over the years, Let’s Play Math! blog has grown into a sprawling mess of 1,000+ posts and resource pages. It gets harder every year to find the particular activity or game you’re looking for.
I write primarily about math, but I have other interests as well, and sometimes those sneak through onto the blog — a bit of fiction, some Shakespeare, and of course, stories about my kids.
A couple years back, I put together the following lists of my top 10 (more or less) favorite blog posts from each category. I’ve written many new posts since then, but these oldies are still good reading.
Skim. Click. Explore. Have fun!

Beware! As concepts get harder, pushing your student could lead to math anxiety. Instead, make math a cooperative effort by using Buddy Math. Or intersperse your textbook math lessons with fun, low-pressure games and activities.

Let’s Play with Algebra & Beyond
Algebra, geometry, pre-calculus and more… I don’t tend to write as much about high school math, because my kids are mostly independent learners by that stage. They also take classes at the local community college, which gives them a few grades on their transcripts from somebody other than Mom. (Mom is a tough grader!)

Understanding and Teaching Elementary Arithmetic
As you study, remember the PUFM goal: “Know HOW, and also know WHY.” Most of us already know the “how” of these topics, but we are constantly learning new things about the “why” (and the “how to explain”).

I Wonder about Solving Word Problems
Why do so many people hate word problems (aka story problems)? My children have always preferred their math to be “about something,” rather than working with abstract numbers. Word problems are like little puzzles or mini-mysteries to solve — what fun!

Use Bar Diagrams to Think Through Word Problems
I love the problem-solving tool called bar diagrams (or Singapore math models), which I learned about from Singapore Primary Mathematics but which can be easily applied in any math program. A visual form of algebra, these diagrams will help all students learn to reason their way through word problems.

Let’s Play with Math History
The story of mathematics is the story of interesting people. They faced the normal challenges of daily life as well as the creative challenges of mathematical imagination. It’s a shame that our children see only the dry remains of these people’s passion.

Explore the Math Carnivals
A blog carnival is a collection of blog posts loosely related to a given topic. Carnivals give bloggers a chance to reach a wider audience than just their regular readers, and they give readers interested in the topic a chance to access a wide variety of articles at once. Here are the math carnivals I’ve hosted, plus a couple of hodge-podge “carnivals” of my own.

The Mathematical Adventures of Alexandria Jones
Just before the turn of the century, I tried my hand at fiction writing for a short-lived newsletter. A few years ago, I dusted off my newsletter issues and began to republish the adventures as blog posts. Check out my index page:

My Thoughts on Teaching Math
Many teachers are concerned about the amount of material they must cover in a course. One cynic suggested a formula: since, he said, students on the average remember only about 40% of what you tell them, the thing to do is to cram into each course 250% of what you hope will stick.
