Welcome to the 97th edition of the Math Teachers At Play math education blog carnival: a monthly smorgasbord of links to bloggers all around the internet who have great ideas for learning, teaching, and playing around with math from preschool to pre-college.
A few articles were submitted by their authors, but most were drawn from the immense backlog in my rss reader. If you’d like to see your blog post featured next month, be sure to send it in yourself. Our hosts are busy parents and teachers who have limited time to scour the Internet for goodies.
To add a bit of color, I’ve thrown in several favorites from my newly updated Math with Living Books pages. Some (affiliate) links go to Amazon.com, where you can read descriptions and reviews — but there’s no need to buy. Most of these books should be available through your local library.

Please: If you enjoy the carnival, would you consider volunteering to host sometime this year? 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, please speak up!
And now, let the mathematical fun begin!

Talking Math with Kids

- Joshua Greene (@JoshuaGreene19) writes Ode to a bead string (a non-poem poem): “One of the cool things about open play with math manipulatives is that it provides a lot of easy entry points into short math chats.”
- Dan Finkel (@MathforLove) explains How to help your kids fall in love with math: a guide for grown-ups: “Think out loud. Your child is imitating everything you do, and the more you can narrate your thoughts, the better a model of thinking you can be.”
- Crystal Wagner (@Tri_Learning) shares several Math Games to Play in the Car: “Or maybe you are waiting in line at the grocery store or doctor’s appointment. Turn these times of waiting into learning opportunities.”
- Caroline Mukisa (@MathsInsider) lists 11 Award Winning Math Books to Share With Your Child: “Whether you want to introduce a young child to their very first math concepts or supplement an older child’s math curriculum, this list is for you.”
- Christopher Danielson (@Trianglemancsd) shows how The sequence machine can launch math conversations with older students: “Now you can generate number sequences, without being distracted by the multiplication facts.”
Help inspire your kids to try writing their own unique problems. Includes a wide range of math topics and concepts: money and time, fractions, percentages, geometry, logic, and multi-step problem solving.
