Do you have a favorite blog post about math activities, games, lessons, or hands-on fun? The Playful Math Blog Carnival would love to feature your article!

We welcome math topics from preschool through the first year of calculus. Old posts are welcome, as long as they haven’t been published in past editions of this carnival.

Click here to submit your blog post

**Don’t procrastinate: The deadline for entries is this Friday, November 20.** But if you wait that long, you’ll forget. So send in your submission today!

The carnival will be posted next week (or maybe the first week of December) by Sonya at Arithmophobia No More blog.

**Since this carnival wraps up a rough year, Sonya is looking especially for holiday math posts. Or anything that sparks math joy!**

Have you noticed a new math blogger on your block that you’d like to introduce to the rest of us? Feel free to submit another blogger’s post in addition to your own. Beginning bloggers are often shy about sharing, but like all of us, they love finding new readers.

### Need an Idea-Starter?

If you haven’t written anything about math lately, here are some ideas to get your creative juices flowing…

**Talking Math with Kids:**Children often have surprising insight. Even when they’re confused about math, their point of view can open our adult eyes to new understanding. Share your kids’ stories.

**Games or Activities:**Do you have a game, activity, or anecdote about teaching math to young students? We’d love to play along.

**Lesson Ideas:**This section is for arithmetic explorations, geometry puzzles, trig investigations, contest-preparation tips, and more. Can you make math topics come alive, so they will stick in a student’s mind?

**Teaching Tips:**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!

**Mathematical Recreations:**What kind of math do you do, just for fun?

Hello! I commented here during last month’s MTBoS challenge. We agreed that if I used one of your games in my classroom, I tell you about it, so here goes! (I leave my comment here since it’s your most recent post, not because I’m trying to submit an article to MTaP.)

Anyway, I played Tax Collector with my sixth graders today, and they seemed to enjoy it very much! I began with me as the tax collector and the class as the tax payers. As it turns out, the first number chosen was 11 — and the end, the class just narrowly lost to the tax collector, 110-100. If they had started with 19 (or even 17) and made all the same subsequent choices, they would have won the first game!

Afterwards, I divided the class into pairs, with one student as the tax payer and the other as the tax collector. No tax payer wins, or comes quite as close as our initial game with the whole class, even though by now they knew that it was best to start with a large prime like 19. A few tax payers believed they had won, but often it was because the tax collector didn’t take all the factors correctly — for example, a tax payer started with 20, and the collector took only 10 instead of 1, 2, 4, 5 as well.

All in all, it was the most fun we had in class in a while. Thanks for the activity!

Thanks for the update. I’m glad you enjoyed the game!
