Welcome to the inaugural edition of the Math Teachers At Play blog carnival! I hope you enjoy this collection of tips, tidbits, games, and activities for students and teachers of preschool-12th grade mathematics.
For this first carnival, I’ve drawn several recent posts from my blog reader as examples of the types of posts I’d love to include in future editions of Math Teachers at Play. I tried to find something for everyone, from multiplication drill for elementary students to advice for understanding high school math equations.
Let the mathematical fun begin…

As Liping Ma showed, there is more to understanding and teaching elementary mathematics than we often realize. Do you have a game, activity, or anecdote about teaching math to young students? Please share!
- For my entry in the carnival, I offer a homeschooling friend’s idea to help her daughter remember Cute Math Facts for Visual Thinkers.
- Maria Miller at Homeschool Math Blog will help you teach the basic multiplication facts with her first math video: Structured Drill to Learn Multiplication Tables.
- Or you may want to challenge your students’ mental math muscles and help set a world record with World Math Day. Students from 150 countries participated in last year’s event. It’s open to ages 5-18, and it’s free!

This section is for arithmetic lessons and number theory puzzles at the middle-school-and-beyond level. We would love to hear your favorite math club games, numerical investigations, or contest-preparation tips.
- To help your students put big numbers in perspective, Dave Marain at MathNotations asks: Was the First Super Bowl More or Less Than a BILLION Seconds Ago?
- I would have loved to sit in with the middle school math team when Jonathan, who blogs at jd2718, started Teaching Off Topic 2.
- Over at dy/dan, Dan Meyer ponders the story of The Woman Who Didn’t Swim Across The Atlantic. What would your students make of those numbers?
- Brian at The Math Mojo Chronicles admits, “When I was in my thirties, I still couldn’t do long division,” and he shares three great books for self-motivated learners in Learning Math — It’s Never Too Late.
ALGEBRA & GEOMETRY

Can you explain why we never divide by zero, or what is wrong with distributing the square in the expression ? Struggling students need your help! Share your wisdom about basic algebra and geometry topics here.
- Dan Greene at The Exponential Curve offers his students a chance to earn a sweet prize when they review Factoring Trinomials (Part 1). I love the idea of this worksheet/puzzle — I think we’ll use it as a treat for our last day of co-op classes.
- Mr. K at Math Stories blog is feeling Clueless. What do you think — would your students get this geometry warm-up puzzle, or not?
- Mark C. Chu-Carroll of Good Math, Bad Math passes on a chart that could have come straight from How to Lie with Statistics. Can your students spot the problem in Financial Morons, and Quadratics vs. Linears?
- My students love fractal activities — do yours? Xi at 360 blog offers step-by-step instructions for constructing A Pop-Up Sierpinski Valentine Card. I’ll have to bookmark that for next year!

Like most adults, I have forgotten enough math to fill several textbooks. I’m eager to learn again — but math books can be so-o-o tedious. Can you make upper-level math topics come alive, so they will stick in my (or a student’s) mind?
- Murray of squareCircleZ offers some valuable advice for students in How to understand math formulas. This is a great follow-up to his article How to learn math formulas.
- Okay, so perhaps I haven’t forgotten as much as I think. I do remember enough to find the sad humor in Alive but Grading, Rudbeckia Hirta’s most recent Learning Curve.

What kind of math do you do, just for the fun of it?
- Bill Lombard of Mr. L’s Math likes to keep a puzzle or two up his virtual sleeve, and he shares a few in his Friday Afternoon Lifesavers series. I’m printing out The Game of Hex for my co-op classes this week.
- Tanya Khovanova offers a treat at her Math Blog: Five Linguistics Puzzles translated from the Russian book 200 Problems in Linguistics and Mathematics.
- Meanwhile, Scott Franklin has been sharing stumpers over at Natural Blogarithms. His Number Puzzle #7 is a divisibility challenge from the 2006 AMC 10/12B.
- And don’t miss this week’s Monday Math Madness #26: Been Around the World. You have until Monday night to send in your answer to this challenging puzzle from Quan Quach at Blinkdagger.
ABOUT TEACHING MATH

Other teachers’ blogs are an important factor in my continuing education. The more I read about the theory and practice of teaching math, the more I realize how much I have yet to learn. So please, fellow teachers, don’t be shy — share your insights!
- Over at Out In Left Field, Katharine Beals continues her series of Problems of the Week with 6th grade Connected Math vs. Singapore Math. Would you let a tarantula crawl up your hand?
- Keith Devlin poses some intriguing questions in his latest series on math education: How Do We Learn Math? and Should Children Learn Math by Starting with Counting?
And that rounds up our first Math Teachers at Play carnival. I hope you enjoyed the ride!

Why a New Carnival?
I really do enjoy the Carnival of Mathematics, most of the time, but I must admit that many of the posts go right over my head. And my middle-school level contributions often feel out of place (to me, at least), like toddlers at a high society cocktail party. On the other hand, the more general edu-blog carnivals (see sidebar) have grown so large that it’s nearly impossible to browse all their posts. I wanted something smaller and more “relevant” — more tightly targeted to my interests. And so, not finding the type of blog carnival I wanted, I selfishly decided to create one.
I plan to post these round-ups biweekly — if I can keep up with that pace amidst the hurly-burly of our homeschool lifestyle — alternating with the Carnival of Mathematics. More information may be found on the Math Teachers at Play blog carnival index page.
The next edition of the carnival is scheduled for March 6. If you would like to contribute, email me or use this handy submission form. Posts must be relevant to students or teachers of preschool-high school mathematics. Old posts are welcome, as long as they haven’t been published in past editions of this carnival.
Oh, and if you’d like to take a turn hosting the Math Teachers at Play blog carnival, please speak up!
