Ying and the Magic Turtle

We at Natural Math were thrilled when Dr. Sue Looney, a veteran mathematics educator and provider of professional development, approached us with the book’s concept: retell an ancient legend about magic squares as a children’s story. We want to see many more mathematical story books like Life on the Infinite Farm (infinity), Anno’s Magic Seeds (exponential growth), and Funville Adventures (functions and functionals).

“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. I wish I read it as a young child, so I could pretend-play to be Ying, saving my land – with math!

Children ages 5 and up, parents, and teachers can enjoy the book for its rich beauty in mathematics and as an ancient legend. It is the kind of story to revisit over and over again. This book is perhaps best experienced with someone, as a read-aloud or read-together. When reading, we learn of Ying’s trouble, and we root for her to find her solution. We find ourselves drawn into the life problems that Ying is facing, but also drawn into the inherent mathematics of the story. It is through the beauty of the pattern of the dots on the turtle’s shell that the solution is finally found and the land is saved.

We can appreciate each scene as we read, and then pause and predict what might come next. We can play with the mathematics, solving right alongside Ying. We can delve deeper into the power of magic squares by working with puzzles presented at the end of the story. Best yet, there are unsolved problems in number theory even a young child can try, such as finding all the possible magic squares of a given size.

Kids Build Together – Math Readiness in Early Childhood

What is math readiness? Is it really possible to teach math readiness to very young children – toddlers and preschoolers? What does it look like? For several years Carolyn Galbraith ran a play and learning center, focusing on math readiness for preschool children. In this post, Carolyn describes some of her experiences and the outcomes she observed.  

We are lying on our backs looking up  at the ceiling, searching for shapes. We see squares, rectangles. The smoke detector is a circle. One of the kids points out that the joins between the ceiling panels make crosses, and excitedly: “Parallel lines!”

When my kids were small, I ran a play & learning center in a small town outside Sydney, Australia. It held mostly building blocks and was a place where parents and kids could come and build whatever they liked. Inspired by Papert’s constructionism, it was a space where people could learn by constructing items meaningful to them, and sharing them with others. That’s why I called it Kids Build Together.

On Monday mornings I ran a math readiness group. It had mostly 2 to 4 year-olds. There were three main areas of focus – enjoying patterns, enjoying problems, and enjoying the process. We read a lot of math-themed picture books, tussle with simple problems. I tried to always end with a math-themed poem. Here’s a sample of one of our sessions:

“Today we’ve sung “Round about the circle” and passed a bag around with different shapes. Now the kids are going to try to fit them together. There’s no right answer, and it’s fun to see the different ways that the kids turn and feel and explore the properties of their shapes.

Next we read a gorgeously illustrated book about spirals in nature called “Swirl by Swirl”  by Joyce Sidman. Afterwards, the kids use different colored stones to make their own spirals.  They’re beautiful.

We’ve been reading “Measuring Penny” by Loreen Leedy and using different ways to measure things. Today the kids use big blocks to build towers as tall as themselves. They’re predicting how many blocks they’ll need, and I write it down on the board. They’re surprised to discover it only needs 15 blocks, rather than 100, to reach their height! I give them a measuring tape as another way to check their height, and 100 cm is close – so their predictions weren’t far off, after all.

To finish off I read a poem about time “Twenty-Four Hours” by Charles Causley. The kids love listening to poetry, the rhythm captures them instantly.

When I think back to learning math when I was at school, music, stories and games were the things I wished we used (I remember trying to design my own curriculum back in high school!) Finding the incredible mathematical patterns in nature, from fractals to Fibonacci spirals, has been a wonderful discovery of adulthood, as well as learning the stories of the mathematicians themselves. I hoped to share the pleasures of discoveries like these with the kids and their parents, and let them in on a secret – that math is more than memorizing numbers, and that readiness for math can be readiness for enjoying life.

Now my two kids are at school, and my center is no more. I help run a math class for the little ones at the local school, and include some Math in Your Feet dance activities there. I also tutor some children with literacy and numeracy challenges. It’s been fun sharing some of the resources with the older ones, such as the book about Fibonacci and the ideas of fractals.

It’s now I realize why all the work on symmetry in the younger years is essential – so much of mathematics is symmetry and balance! There’s not much time to cover it in school, a lesson or so. The ones who’ve spent years building with blocks are immediately advantaged. I encourage the parents of the older ones to bring the Lego back out, and build together; to walk in nature and observe the wonderful math in flower petals and tree branches. The secret hasn’t changed with their ages; math is still more than memory, and is still an important part for enjoying life.

Enjoyed this story and feel inspired to try these math activities with your preschoolers? Let us know how it goes. Do you have a math story to share? We can’t wait to hear from you!

Meet new Natural Math authors Sam Coskey, Paul Ellis, and Japheth Wood. The working title of their book is The Fantastic Five. The book is for teachers, parents, and math circle leaders with students ages 10 and up as well as younger friends. It offers rich and original problem-solving activities in the contexts such as a trip to Mars or traditional Sona storytelling from Angola/Congo area. The authors write:

We are collaborating on a book of five math circle activities that we plan to publish with Natural Math. We would love it if you would agree to be a “beta-reader” of one chapter (or more, if you have time). If you have an appropriate forum in which to try the activity (such as a math circle or family math at home) that would be wonderful. If not, we would be happy if you would just read the chapter and provide feedback by email.

You are welcome to provide feedback in any form that you like. However, if you wish to have some guidance, we’ll suggest questions that we brainstormed together.

Valentine’s Craft Day at Natural Math – ages <3 and up

Make Valentine’s Day crafts to celebrate loving one another… in the context of mathematics!

Grow your math eyes on these little field trips inspired by topology, dynamical systems, and algebraic geometry for the young, the very young, and the young at heart.

Know another romantic math craft? Tell us in the comments!


Half a heart is a teardrop… so, love! (Age 2+)

Half a heart is a teardrop... so, love!

Make math: Fold paper in two. Sketch a teardrop in such a way that the fold forms one side of its triangular top part. Cut it out, open, and decorate the heart-shaped greeting card. My teen and I decorated with a cardioid (see below).

Grow your math eyes: What interesting shapes can you fold or unfold into other interesting shapes? What if you fold more than once? Choose shapes to experiment, on paper or in your imagination.

Topic: Mirror Symmetry. Inspired by Big Math: #14 Algebraic Geometry, #53 Differential Geometry.

Bonus:

Valentine Double Doodle


Mobius Hearts: Interlocked! (Age 3+)

Mobious Valentine

Make math: Cut out two strips of paper and glue them together to form the + sign. Attach the opposite ends, with a twist, as if making Mobius strips. Cut the strips through the middle, and Mobius Hearts will happen! Video instructions:

Grow your math eyes: Try twisting two or more times. Try cutting 2/3 of the way rather than through the middle. What other surfaces can you make by connecting, twisting, and cutting paper strips?

Topic: Surfaces. Inspired by Big Math: #54 General Topology, #57 Manifolds.

Bonus:

Roses are red. Violets are approximately blue.
A paracompact manifold with a Lorentzian metric,
can be a spacetime, if it has dimension greater than or equal to two.

Exponential Love: Heart Fractal (age 5+)

Fractal Valentine Multiplication Explorers

From participants in the Multiplication Explorers course

Make math: Draw a heart. Mark two or more points around it, for example, up top. Draw smaller hearts there. Mark the same points on them, and draw even smaller hearts. Keep going. Decorate your heart fractal, put it on a wall, or use as a greeting card.

Grow your math eyes: How tiny can your hearts become? Will you run out of space on paper if you keep going and going and going? How many hearts do you add to your fractal at each step of the process? For more versions, choose how many hearts to add at each step, how much to shrink at each step, how to turn the hearts around – then observe what happens.

Topics: Fractals and exponential growth. Inspired by Big Math: #11 Number Theory, #37 Dynamical Systems.

Bonus:

Cardioid Greeting Card: Make Heart-Like Curves from Straight Lines (age 5+)

Cardioid by Almost Unschoolers

Image by Almost Unschooling

Make math: Trace a plate on scratch paper and cut out the circle. Fold it in half a few times, as if for making a snowflake. Unfold; your circle is now split into equal parts.

Circle folding

You can also print out a marked circle, or use a protractor to mark it. Then follow instructions from MathCraft for drawing, or Almost Unschooling for string art. The craft involves skipping the dots by one and two, again and again. The repetition feels meditative, and there is a beautiful surprise at the end. The heart-shaped curve emerges as if by magic! Decorate it and put it on the wall or use as a greeting card.

Grow your math eyes: What other curves can you make out of straight lines? Choose your own “recipe” for skipping dots around a circle, and see what happens. What if you used a triangle or a square instead?

Topic: Curves. Inspired by Big Math: #14 Algebraic Geometry, #52 Discrete Geometry.

Bonus:

Math-o-grams: Graphs of Love (age 5+)

Math-o-gram Desmos

Make math: Customize variables and make your own greeting cards out of pretty graphs. Go to Desmos Math-o-Gram site to play and share the love.

Grow your math eyes: Peek behind the scenes to experiment with the equations. Replace numbers or functions in them and see what happens. Young children can start experimenting without knowing much (or anything) about the functions.

Topic: Functions and graphs. Inspired by Big Math: #14 Algebraic Geometry, #33 Special Functions.

Bonus:

The heart Earth theory from Wolfram Alpha.
