5 Fabulous Activities for Your Math Circle

Five Fabulous Activities for Your Math Circle – a guidebook for teachers, parents, and math circle leaders

A math circle is any group of people gathering to explore mathematics—it could be in your home, in school, or even online. Math circle activities are often interactive, exploratory, flexible, open-ended, and social. This might sound like a really fun idea, but how does one make it happen? Five Fabulous Activities for Your Math Circle will help show you how. This book is a guide and a collection of recipes for anyone who wants to help others discover joyful and challenging math. Our book will help you guide mathematical learners of a wide variety of ages. We primarily target middle and high school students. We have also included activities and explanations intended for younger math friends. The underlying mathematics can be of interest even to adult learners, including ourselves!

Bright Brave Open Minds

Bright, Brave, Open Minds: Engaging Young Children in Math Inquiry

By Julia Brodsky.

I will share with you what I have learned as I tinkered with teaching problem solving to curious young children, ages six to eight. The purpose of this book is to invite you to experiment with your own children or students, without any preconceived notions of how the outcome will look. Instead, allow your personal taste and the children’s feedback to guide you.

Available in paperback and ebook formats. 372 pages. ISBN 978-0-9776939-3-1

Mathematics is a creative activity, like music. It requires some technique, and the technique has to be taught, but the main point is elsewhere—it is all about creativity, a sense of enjoyment, and higher purpose. This book goes a long way in that direction.

– Ivar Ekeland, author of The Cat in Numberland

Sue VanHattum has assembled a marvelously useful and inspiring book. It is filled with stories by people who don’t just love math, they share that love with others through innovative math activities. Playing with Math is perfect for anyone eager to make math absorbing, entertaining, and fun.

– Laura Grace Weldon, author of Free Range Learning


Camp Logic Cover

Camp Logic: A Week of Logic Games and Activities for Young People

By Mark Saul and Sian Zelbo. Illustrations by Sian Zelbo.

This book offers a deeper insight into what mathematics is, tapping every child’s intuitive ideas of logic and natural enjoyment of games. Simple-looking games and puzzles quickly lead to deeper insights, which will eventually connect with significant formal mathematical ideas as the child grows. 

This book is addressed to leaders of math circles or enrichment programs, but its activities can fit into regular math classes, homeschooling venues, or situations in which students are learning mathematics on their own. The mathematics contained in the activities can be enjoyed on many levels.

Available in paperback and ebook formats. 134 pages. ISBN 978-0-9776939-6-2


“Most students encounter math through boring, rote memorization and drill and kill. Camp Logic reverses the trend by offering teachers fun, inquiry-based activities that get to the deeper elegance and joy of math with adaptations for different skill levels and learning environments. The work of Saul and Zelbo has redefined how math is taught in our programs.”
– Meghan Groome, Executive Director of Education and Public Programs at the New York Academy of Sciences


Moebius Noodles: Adventurous Math for the Playground Crowd

By Yelena McManaman and Maria Droujkova. Illustrations by Ever Salazar.

Available in paperback and ebook formats. 88 pages. ISBN 978-0-9776939-5-5



Multiplication Models Poster

By Maria Droujkova and Dmitri Droujkov. Illustrations by Victoria Kolchenko.

Natural Math multiplication poster was created by and for children, parents, teachers, and mathematicians. It uses clear, fun pictures to present twelve common multiplication models. Each model comes alive in two artistic examples with formulas, the types of numbers appropriate for the model, and a list of activities.

Available in 24 x 36 inch glossy poster and printable files. ISBN 0-9776939-1-0

Excellent poster. I’ve been mesmerized by it. My four year old is interested in math and she spends 15 minutes staring at it every day. This poster has sparked lots of grown up conversations about math and multiplication and what it really means, and has inspired me to come up with new and more creative ways to present math concepts to my young kids

– Tracey Seyer, parent

This is a perfect compliment to my multiplication unit with 2nd and 3rd graders! Affordable, attractive. I just love it!

– Jackie Keepers, teacher

    Why am I not receiving your newsletters?

    • MariaD says:


      Usually it’s because of overactive spam filters. Find an email with words “Natural Math” from – look in your social and spam folders if you don’t see it in the inbox. Let me know how it works! Glad you are interested. I am quite fond of our newsletters.

  2. monica selva says:


    I would like to buy the pdf versions pf playing with and camp logic. Unfortunately when I try it my cart is charged with shipping costs, why is it? I don’t want the books to be sent to Chile, I would like to have them now.

    • MariaD says:

      Hi Monica,

      I just tried to order PDFs while selecting Chile, and our shopping cart did not try anything wrong. Do you think you might have a paper book in your cart as well? If so, press the X (cross) sign next to it to remove it. If it keeps glitching, please let me know and I will send you PDFs by email. These are great books and I hope you enjoy them!

  3. Debbie G says:

    My 11 yr old son used to love math. At an early age he figured out concept of numbers, recognized patterns, etc. This last year, I have noticed he is not so enthusiastic about math. I can tell he needs a deeper understanding. Often his teacher will teach a “rule” in math. My son can easily memorize this “rule” and implement it, but he often wants to know why he is doing the rule or why this rule works. Often the teacher cannot explain why; “it’s just the rule”. Also many lessons now are taught on the computer. Don’t get me wrong, my son loves to play on the computer, but he often says how he does not like lessons being taught on the computer. He would rather get on the white board and figure things out with his teacher. This unfortunately is not able to happen. I see his spark, his love and curiosity of mathematics drifting. Since he was young he always spoke of being a mathematician. He does not talk about that anymore. He will be finishing up 8th grade math this year. Do you have any resources for kids his age? Any advice for us in how to get him loving math again?

    • MariaD says:


      Sorry about the delay – this has been misplaced in the moderation queue. It’s sad about your son, and I hope you find ways to fuel his fire again. As you said, it’s about people. Working with someone who cares, talking with someone who shares your passion. Have you tried to look for local math circles, where you live? They are usually ran by enthusiasts. If not math, maybe other math-rich experiences like robotics? Is there a way to find a creative math person to work with him on mathematics?

      We do have events for older children like this, sometimes. I hope to have more, so your son and others find online friends. Meanwhile, take a look at what’s happening online at The Art of Problem Solving – maybe their group classes would be interesting for him?

  4. Elizabeth says:

    Hi, I see your book “Bright, Brave, Open Minds: Engaging Young Children in Math Inquiry” on Amazon but not here. Is that the only way to buy it? There is no info on the book and also no e-book version – shipping is a bit of an issue as I’m in South Africa. But really want to read it!

    Kind regards

    • MariaD says:


      The Amazon thing is a fluke – not intended to happen, just the launch gone in a slightly asynchronous way. We should launch this book here this week, with all the usual electronic versions and name-your-price PDF. Stay tuned!

  5. Mimi says:

    Thank you for offering a more enjoyable math experience to our family. We are a homeschooling family and I was wondering if:
    1. One copy of any of your book would all ages ( ages 9,7,5 3 and 18mths)?
    2. do you have a coupon that I can apply to my purchase?

    Many thanks

    • MariaD says:

      Hi Mimi,

      I would say Moebius Noodles and Playing with Math have materials for parents or teachers of children of all ages. Camp Logic is for your older two, and Socks Are Like Pants for your middle three children.

      We will have a sale on paper books soon (the newsletter will announce it). Meanwhile, PDFs of all our books are available at prices you choose yourself. It’s a part of our open license promise to do so!

  6. Emma says:

    What would your shipping to Australia be like?

    • MariaD says:

      It’s probably about 15 dollars for a book. I suggest you buy several with friends (there’s also a nice discount if you do so). You can put things into the shopping cart and it will tell you shipping before you have to pay.

  7. Megan Fennell says:

    Is there anywhere that is selling these in Canada? The shipping is half again the price of the books. And I want them SO BAD! But I can’t afford to pay for the books AND the shipping . (I’m a paper person. I can’t do ebooks. They make me cross-eyed!)

    • MariaD says:

      Megan, has at least some of these books. You will get a better price here if you buy our bundle. Another option to save on shipping, if you want just one or two titles, is to buy with friends. We have large discounts on 5+ books of the same title. I hope one of these options works out for you.

      • Megan Fennell says:

        Currently doesn’t have any of them. They “carry” them, but they don’t actually have them.
        I WANT to buy the bundle, but it goes from $50USD to $75, which is really like $115 after the exchange. That’s a lot of money!
        I would love to get the bulk discount, but I live on a tiny island in the middle of nowhere, so have no one to go in on them with.
        Have you guys thought about selling through Chapters here in Canada?

        • MariaD says:

          Please tell me more about Chapters. I’ll see what I can do. Also, I will look into Canada shipping closer for prices.

          • Megan Fennell says:

            Chapters is just a big box book store here in Canada. I usually shop locally, but Chapters would reach all of Canada in one go, and it offers free shipping to us Canadians!

  8. Nabanipa Roy says:

    Hi Megan – I am thinking of purchasing some of the books on your site. I wasn’t very sure which age groups each of the 5 books on your site are meant for. Can you help me understand the target age-group for each of the 5 books?


    • MariaD says:

      Glad you are interested! All books are for parents and teachers, and can be adapted for all ages, but might be easier as-is with children who are about:
      Moebius Noodles – birth to twelve
      Camp Logic – five to teens
      Playing with Math – all ages (it’s an anthology)
      Open Minds – five to twelve
      Socks Are Like Pants – three to eight

      I hope it helps!

  9. Carol Frey says:

    Ok, I feel silly, but I just purchased the bundle of ebooks and can’t figure out how to put the kindle files into m library of kindle books on my kindle. I’ve already downloaded them to the kindle, via my email, but they sit it “Documents,” and I want them to live in the Kindle book library like other books. Can you give me a clue or point me to an FAQ or list of instructions?

    • MariaD says:


      Here are PC instructions for Kindle. Not exactly obvious! Let me know if you are on a Mac – the instructions are slightly different. Please try them and let me know if a step does not work. We’ll then try to figure it out.

      1. Connect your Kindle Touch to a computer with the USB cable.
      2. Open Windows Explorer. Your Kindle Touch will appear in the same location as external USB drives usually appear, in the “Computer” or “My Computer” menu.
      3. Open the Kindle Touch and find the folder named “Documents.”
      4. Locate the downloaded .moby file and copy or drag it into that Documents folder
      5. Eject Kindle from the computer. Your content will appear on the Home screen.

    • barbaracohn says:

      I have a Mac and have also had problems downloading to my Kindle. Can you please send me th instructions for the Mac.

      • MariaD says:

        Hi Barbara,

        With Mac or PC, you can attach your Kindle with a USB cable, and then drag and drop the .moby file onto your Kindle.

        Several online sources claim the email is easier. It works from any device to Kindle. Please try this and let me know how it works. I hope you enjoy your books!

        1. Your Kindle has an email address for file downloads. To find it, go to using your browser. Tap on “Your Devices,” then choose the relevant Kindle from the gallery below. Next to “Email,” you’ll find the Kindle’s email address.

        2. You need to tell Kindle your own email address (for safety). Click “Settings” and scroll all the way down to the “approved personal document e-mail list.” Click “add a new approved e-mail address,” and add the email address you intend to send your books from.

        3. Make sure your Kindle is attached to a Wi-Fi or 3G network, so that it can receive emails.

        4. Attach the .mobi file to an email, with any subject, and no body in the email. Send it to your Kindle’s email address. It should appear on your Kindle shortly.

  10. Aylin Yilmaz says:

    I have a 5 year old. Which book would you recommend?

    • MariaD says:

      Hi Aylin,

      Thank you for your interest! We added a guide to the beginning of the page with recommendations on where to start, by ages. I hope it helps!

  11. Victoriaderuyter says:

    What manipulatives/learning tools would be necessary to implement the teaching in the books. I am interested in buying the ebook bundle to use while we travel however worried that they will then tell me I need a lot of manipulative which I will not be able to carry around whilst we travel. Will I be able to do the books justice with very little learning instruments?

    • MariaD says:

      Hi Victoria,

      We made a big effort not to require special manipulatives. People use these books all over the world, and situations vary. An activity here or there calls for yarn, scissors, or a mirror, but the vast majority of them can be done with only paper, markers, and found stuff like pebbles.

  12. Romennaj says:

    Since I have Playing with Math, can I get the Bundle without Playing with Math and with Avoid Hard Work?

  13. math games says:

    Thank you for sharing those wonderful resources

  14. Olga says:

    Hi! When do you anticipate the latest book be available? (10th one, from the latest Kickstarter campaign).

  15. Heather C. says:

    I’m sorry to leave this as a post rather than a message, but I’ve just purchased PDF of two books twice and cannot download them. I purchased “Socks are Like Pants, …” and “Five Fabulous Activities…” and pay through Paypal, then it takes me to my completed order and says I’ve purchased them, but when I click on the links it just takes me back to the page with the information about the book and doesn’t let me download anything. Please Help!

    • Heather C. says:

      Never mind. I just saw my order come through my email. Thank you.

      • MariaD says:

        Thank you for supporting Natural Math for ten years, and sorry about the issue! There was a glitch with PayPal, but everyone should have received their books and courses by now. Do not hesitate to write any time to talk about children learning mathematics. I appreciate you letting us know!
