Holiday Math and More: Math Teachers at Play #114

Do you enjoy math? I hope so! If not, the links in this post just may change your mind.

Welcome to the 114th edition of the Math Teachers At Play math education blog carnival — a smorgasbord of articles by bloggers all around the internet who have great ideas for learning, teaching, and playing around with math from preschool to pre-college.

By the way, I found a cool, semi-self-referential trivia tidbit about our carnival number: 27 − 14 = 114. And if you put 114 dots into a 1←7 Exploding Dots machine, you’ll get the code 222. Pretty neat!

As you scroll through the links below, you find several puzzle graphics from the wonderful Visual Patterns website. Use them as conversation-starters with your kids: What do you notice? How does each pattern grow? For older students: Can you write a formula to describe how each pattern? What will it look at stage 43?

A BIT OF FUN

Setting the mood: Enjoy this bit of seasonal fidgeting from Vi Hart (@vihartvihart).

If you don’t understand some of the references, that’s normal! Pick a phrase, Google it, and enjoy the fun of learning something new.

And now, on to the main attraction: the blog posts. Some articles were submitted by their authors; others were drawn from the immense backlog in my rss reader. If you’d like to skip directly to your area of interest, click one of these links.

Let the mathematical fun begin!

SEASONAL MATH ACTIVITIES

You don’t have to celebrate Christmas to enjoy many of these activities — but really, I couldn’t find much for the other winter holidays. A few calculation worksheets with clip art, which is not my idea of playful math.

Do you know of any great math-related seasonal games, crafts, or activities I missed? Please add them to the comments section below!

• Clarissa (@c0mplexnumber) demonstrates how to make beautiful, challenging origami snowflakes. She recommends beginners try the first few folds — which create a pretty cool design on their own. Let it Snow… You may also enjoy her other Christmas projects.

ELEMENTARY EXPLORATION AND MIDDLE SCHOOL MASTERY

• If you’ve followed my blog for long, you know I like to play with dot grid paper. So of course, I was delighted to find Spatial Learning’s Isometric Dot Paper Activities, and the follow-up Cube Stack Activity. What a great way to build geometric intuition!

TEACHING TIPS

• My daughter is struggling with online homework in her calculus class — not because the math is too hard, but because the interface is anti-intuitive. So David’s (@davidwees) post resonates with me: Online Practice is Terrible Practice. And I love his challenge to find and teach to the Big Ideas of math.
• I’d like to wrap up the carnival with an article you may have seen before. If you haven’t read it, you’re in for a treat. And if you have, well, it’s very much worth re-reading. Annually. As we wrap up the old year and prepare for the new … Francis’s (@mathyawp) Mathematics for Human Flourishing.

“Shalom and salaam, my friends. Grace and peace to you. May you and all your students flourish.”

And that rounds up this edition of the Math Teachers at Play carnival.

I hope you enjoyed the ride.

The next installment of our carnival will open sometime during the week of January 22–26, 2018, at … well, we don’t know!

We need more volunteers. Classroom teachers, homeschoolers, unschoolers, or anyone who likes to play around with math (even if the only person you “teach” is yourself) — if you would like to take a turn hosting the Math Teachers at Play blog carnival, please speak up.

To share your favorite blog post with the carnival, please use this handy submission form. Posts must be relevant to students or teachers of preK-12 mathematics. Older-but-still-relevant posts are welcome, as long as they haven’t been published in past editions of this carnival (at least, not in recent memory).

Past posts and future hosts can be found on our blog carnival information page.
