Do you have a favorite blog post about math activities, games, lessons, or hands-on fun? The Math Teachers at Play (MTaP) math education 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

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.

**Don’t procrastinate:** *The deadline for entries is this Friday, December 1.* The carnival will be posted next week at Let’s Play Math blog.

### Would You Like to Host the Carnival?

Hosting the blog carnival is fun because you get to “meet” new bloggers through their submissions. And there’s a side-benefit: The carnival often brings a nice little spike in traffic to your blog.

If you think you’d like to join in the fun, read the instructions on our Math Teachers at Play page.

Then leave a comment or email me to let me know which month you’d like to take.

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!
