“Denise Gaskins’s work is consistently lovely and playful, so go check it out if you do any journaling or any other sort of mathematical writing with children.”
—Christopher Danielson, author of Which One Doesn’t Belong?
It’s finally here! 312 Things To Do with a Math Journal includes number play prompts, games, math art, story problems, mini-essays, geometry investigations, brainteasers, number patterns, research projects, and much more.
These activities work at any grade level, and most can be enjoyed more than once. It doesn’t matter whether your students are homeschooled or in a classroom, distance-learning, or in person. Everyone can enjoy the experience of playing around with math.
And there’s a new one coming soon, from the wonderful people at Natural Math.
“Long ago in the land of China, there were many rain storms … and the land of China was slowly sinking into the sea. This is the story of how a wise emperor, an observant girl, and a magic turtle saved the villages of China from the great flood.”
So begins the story of Ying and the Magic Turtle.
Children, parents, and teachers can enjoy the book for its rich beauty in mathematics and as an ancient legend.
We can play with the mathematics, too, solving the puzzle of the turtle’s shell right alongside Ying.
And we can delve deeper into the power of magic squares by working with puzzles presented at the end of the story.

Love exploring magical worlds wracked by the struggle of good against evil?
Then don’t miss Teresa Gaskins’s four-book serial adventure, The Riddled Stone.
Those of us who read her earlier books have waited eagerly to hear how the story ends. Two years longer than we hoped, since she had to squeeze in her writing between calculus exams and college essays.
But finally, it’s done!
Now a homeschool graduate, she wrote the last few scenes right at the tail end of her nineteenth year — which means these will be Teresa’s final books as a teen author.
Check them out…
The Riddled Stone: Omnibus Edition, Four Books in One
How can a knight fight magic?
Christopher Fredrico loved the quiet life of a scholar-in-training. Plenty of spare time to spend with his friends. But the night Crown Prince Tyler came to dinner, everything changed.
Falsely accused of stealing a magical artifact and banished under threat of death, Chris leaves the only home he knows.
But as he and his three friends travel towards the coast, they find a riddle that may save a kingdom — or cost them their lives.
Discover the full story of The Riddled Stone, complete in one volume.
A gift she never wanted. A curse she can’t escape.
Alone in the dark, Nora of Yorc feels the dungeon walls pressing in. Even worse, the duke’s sorcery weaves itself around her, unseen and deadly. But as the spell tightens, shy, fragile Nora breaks — and something new takes her place.
Or something old beyond memory.
Nora joined this quest to help her friends. But can she stop herself before the wildness within destroys them all?
Find out in Revealed, the exciting conclusion of Teresa Gaskins’s four-book serial fantasy adventure, The Riddled Stone.
“There are some obvious protagonists and some obvious villains, but Gaskins creates a nice ambiguity around several of the key characters. The plot itself is interesting and engaging with multiple levels of motivation that drive it along.”
“I enjoyed the book and I am absolutely amazed at how such a young author can write so well. I definitely see her going far in her writing career, and I can’t wait to see what stories she publishes next.”
Today we have a guest post — an exclusive tale by Sasha Fradkin and Allison Bishop, authors of the new math storybook Funville Adventures. Enjoy!
Funville Adventures is a math-inspired fantasy that introduces children to the concept of functions, which are personified as magical beings with powers.
Each power corresponds to a transformation such as doubling in size, rotating, copying, or changing color. Some Funvillians have siblings with opposite powers that can reverse the effects and return an object to its original state, but other powers cannot be reversed.
In this way, kids are introduced to the mathematical concepts of invertible and non-invertible functions, domains, ranges, and even functionals, all without mathematical terminology.
We know about Funville because two siblings, Emmy and Leo, were magically transported there after they went down an abandoned slide.
When they came back, Emmy and Leo shared their adventures with their friends and also brought back the following manuscript written by their new friend Blake.
Have you noticed that we live in a wonderful era of mathematical innovation? Not only at the “it’s all over my head” level — which is growing faster than anyone can keep up with — but also at the Cool Math For Kids level.
So many things! I’m sure I forgot one (or several) of your favorite modern-classic math books or toys. I’d love to hear about them in the comments.
And here are a few bits of new playful math. Click, support, and share!
In alternating chapters, Rodi Steinig tells stories about her math circle and exactly what happens there, while her daughter Rachel discusses why so many kids hate math, documents the ways math is taught in the classroom — and ways that can be improved.
When 9-year-old Emmy and her 5-year-old brother Leo go down an abandoned dilapidated slide, they are magically transported into Funville — a land inhabited by ordinary-looking beings, each with a unique power to transform objects.
I had the fun of previewing this book. It’s a cute little fairy tale that should help launch family conversations about math.
Trouble with Monkeys
A boy wants to surprise his dad, but meddlesome monkeys keep getting in the way. The boy is interviewed by the local news, and the story escalates to involve pirates, ballerinas, ninjas — and the magic of our place value number system.
But as with any paperback book, these have one problem. How do I use them without cracking the spine?
When we exercise, we need to warm up our bodies with a bit of stretching to prevent injury. In the same way, we need to warm up a new book to protect it. The process is called “breaking it in.”
It only takes a few minutes to break in a paperback book:
Step by Step
Never force the book but help it limber up gradually, and it will serve you well.
Because my journals are working books, I take the breaking-in process a bit further than shown in the video:
(1) Set the book on its back and follow the process above. Press down each cover, but not completely flat — let it bend at the fold line, about 1 cm from the actual spine. Then press a couple pages at a time, alternating front and back, down flat on each cover.
(2) Flip through the pages of the book forward and backward to limber them up.
(3) Repeat the steps of the video. This time, gently lean the main part of the book away from the part you are pressing down. Aim for a 130–140 degree angle.
(4) Flip through the pages again. For paperbacks, you can even roll the whole book back and forth a bit — gently curving the cover and pages almost as if you’re trying to fold the book in half — to encourage flexibility.
(5) Optional: Repeat the breaking-in process one more time. This time, fold each section back as close to 180 degrees as it will go.
And you’re done!
The pages will still curve in at the fold line, where they connect to the spine of the book. You want that because it makes the book strong. But now they’ll also open up to provide a nice, wide area for writing or math doodling.
Each week, we’ll be playing with the math, language, and logic topics found in a single chapter. I’ll be posting ideas for extension activities, videos demonstrating the concepts for the week, and additional resources. I’m really excited for the opportunity to share all the extra ideas that have been floating around my brain which I didn’t have room to include in the book (as in Marco Polo’s famous words: “I did not tell half of what I saw.”)
