National Math Festival

I’m taking Math On-A-Stick and Which One Doesn’t Belong? on the road—to the National Math Festival in Washington, DC on Saturday, April 22, 2017. If you’re nearby, you should come out and say Hi!

I have two Math On-A-Stick sessions—at 10:00 and 4:30—and one Which One Doesn’t Belong? session at 2:30. The Math On-A-Stick sessions are pure play; the Which One Doesn’t Belong? one is interactive but more talky.

There are lots of other amazing folks doing amazing things with all ages, so come spend the day! It’s free. See you there.

The Summer of Math is back!

We had so much fun the first time around, the Summer of Math is back for a second year, and it has its own webpage!

The basics are the same as last year:

You can head over to The Summer of Math webpage, pay for a subscription, and all summer long (June—August) we’ll ship you awesome, fun stuff that will keep you and your 5—10 year old(s) busy playing and talking math.

You’ll color, count, make patterns, designs and shapes. You’ll read together, draw, and challenge yourselves. You’ll notice. You’ll wonder. You’ll play. And when school starts back up in the fall,

your kids will remember this as the best, mathiest summer ever.

A few small changes include: a new website, three boxes instead of four (but same amount of total mathy goodness, so the net result is higher math-fun density in each box), and a few new things rotated into the lineup (the Truchet tiles are curvy this year!)

Together with a little help from some super smart friends, we’re shooting for a bigger Summer of Math this year, but there is an upper limit on subscriptions. Help us reach it—and as many families as possible—by signing up and by spreading the word.

Fractivities! Coming soon to a school near you! (If you issue the invitation.)

New to Minnesota, Jennifer Schuetz from the Fractal Foundation brought fun fractal activities, or fractivities, to Math On-A-Stick last summer.
Younger students had the opportunity to learn how the Sierpinski triangle is a fractal – by repeating a simple pattern over and over again, smaller versions of the same pattern are created.
Older students created their own Sierpinski triangles with wooden sticks and glitter glue to make a fractal with sticks!
With help from Minneapolis High School art teacher Stephanie Woldom and math teacher Morgan Fierst, we had tons of fractal fun with hundreds of children and their parents from across Minnesota!
Jennifer’s dream turned into reality: job title of visiting artist/mathematician!

Jennifer leads fractal education in classrooms and other venues across Minnesota, the U.S. and the world (her geographic reach is ever-expanding just like fractals!). Fractals are not only appealing to children but also adults… even senior citizens have fun learning about them!

Instructions to 12 fractivities and associated worksheets and answer keys are at:

What do you think about projecting videos of fractal zooms accompanied to original music onto the dome of a planetarium? The Fractal Foundation also does this! More information can be found at:

You can also get in touch with Jennifer to see how to do this. Check out some videos at:

Finally, Jennifer is looking for gigs in schools! Get in touch through the Fractal Foundation Facebook page.

Boxes of Math are here

I and dozens of families across the US, Canada, and England had a blast with the Summer of Math last summer, and now I’m gearing up for the school year version: Boxes of Math.

Starting small with a single option for kindergarten and first grade (five- and six-year-olds, roughly), Boxes of Math will have some overlap with last summer’s Summer of Math, but are targeted at this more narrow age range and the math they’re learning in school.

Boxes of Math consists of:

• A small welcome and introductory shipment before the New Year

• A box for counting and patterning in mid-January

• A box for shape study in late February

• A box for number structures and operations in late March/early April

Each box will have a book, one or more things to get your hands on, and a newsletter with ideas about fun ways to play and to continue the learning in your everyday lives.

Why Boxes of Math?

Inside these boxes are things that help create conversations. They get children thinking about the most important ideas of elementary math.


A few of the objects that will fill the boxes of math.

Most children who struggle with math later on aren’t familiar with these ideas. They know facts by rote, but not in relation to each other. Or they cannot retain the facts because they see no relationships. They can name triangles, but don’t see all polygons as made out of triangles. They can count large numbers of objects fluently, but they don’t notice whether these objects are arranged in rows and columns.

Those are the things this website is all about.

Struggling or not, all children benefit from exercising their math minds through play and conversation.

Boxes of Math offers children and caregivers opportunities to play, experiment, and talk in ways that bring these ideas to life. Noticing rows and columns is a natural outcome of playing with pattern machines. Playing with 21st Century Pattern Blocks is an extended exercise in putting shapes together and taking them apart.

The target outcome of Boxes of Math is children (and families) with a similar relationship to math as they have to literature. They talk about it, see it in their world, and use it to understand their lives in richer, more beautiful ways than before.

Sign up, give it as a gift, pass the word on to friends and neighbors, won’t you?

What Math Looks Like

I’ve been working on some presentations, and I’d like to share with you some images I’ve collected and made along the way, without further commentary. Enjoy.

Which One Doesn’t Belong? is in print!

I am delighted to announce that Which One Doesn’t Belong? A Better Shapes Book is in print and shipping from Stenhouse Publishing this week.

There is a student/home edition, and a set that includes a teacher guide.

I’ll be at Math On-A-Stick at the Minnesota State Fair August 25 through Labor Day. Stop by for a selfie and to get your copy signed!

(Note: The books are not for sale at the fair—nothing is for sale at Math On-A-Stick.)
