To have a successful campaign, we need plenty of people to back the project early. The more supporters we get in these early days, the more likely the Kickstarter platform folks will help spread the news for us.
To give you a feel for the Tabletop Math Games Collection books, I’ve put together a free printable sampler file, with 4 ready-to-play card games you can enjoy today.
(Yes, if you missed last year’s Kickstarter, you’ll also be able to get Volume One.)
Test Out Four Free Sample Games
Math games build mental flexibility and strategic reasoning in players of all ages. And even people who hated math in school can enjoy the friendly challenge of a game.

Games are fun, building a positive attitude toward math. They give students a refreshing break from textbook work and make kids willing to practice their math. Games make math practice enjoyable, something children want to do. We can happily work through many more calculations during a game than anyone would ever want to do on a homework page.
Benefits of Math Games
But more important than the fun, math games push children to think about what numbers mean and how they work. The numbers in a math game are not just meaningless abstractions, but tools that players can use to gain an advantage over their opponent.
A good math game reinforces the idea that math is about reasoning, using the things you know to figure out what you need. Math is not just about getting the right answer. It’s about what goes on in your head on the way to that answer. The answer itself is merely a side-effect. of what really matters, your thinking.
A good math game helps students develop flexibility, the ability to adapt, applying what they have learned to new situations, finding a way to work out the things they haven’t mastered yet. All these add up to a more robust type of mathematical fluency than what many people imagine possible.
English mathematician Henry Ernest Dudeney wrote logic puzzles and mathematical games for several newspapers and magazines, later collected into books. This poem is from Amusements in Mathematics, published by Thomas Nelson and Sons, 1917.
The numbers are simple enough that younger students can solve it by the guess-and-check method. Older students or adults may want to set up a quadratic equation.
Historical Note: In the British currency of the time, there were 12 pennies to a shilling and 20 shillings to a pound (which was also called a sovereign).
The Cyclists’ Feast
’Twas last Bank Holiday, so I’ve been told,
Some cyclists rode abroad in glorious weather.
Resting at noon within a tavern old,
They all agreed to have a feast together.
“Put it all in one bill, mine host,” they said,
“For everyone an equal share will pay.”
The bill was promptly on the table laid,
And four pounds was the reckoning that day.
But, sad to state, when they prepared to square,
’Twas found that two had sneaked outside and fled.
So, for two shillings more than his due share
Each honest friend who had remained was bled.
They settled later with those rogues, no doubt.
How many were they when they first set out?
Did You Solve It?
One fun thing about math is that you really don’t need the answer book. You can always check the math for yourself: Does your answer make sense? Does it fit the story?
Would you like to write a math poem puzzle of your own? I’d love to hear it!

Are your students doing anything special for Pi Day?
Back when we were homeschooling, my kids and I always felt stir-crazy after two months with no significant break. We needed a day off — and what better way could we spend it than to play math all afternoon?
I love any excuse to celebrate math!
Pi Day is March 14. If you write dates in the month/date format, then 3/14 at 1:59 is about as close as the calendar can get to 3.14159etc.
(Otherwise, you can celebrate Pi Approximation Day on July 22, or 22/7.)
Unfortunately, most of the activities on teacher blogs and Pinterest focus on the pi/pie wordplay or on memorizing the digits. With a bit of digging, however, I found a few puzzles that let us sink our metaphorical teeth into real mathematical meat.
What’s the Big Deal? Why Pi?
In math, symmetry is beautiful, and the most completely symmetric object in the (Euclidean) mathematical plane is the circle. No matter how you turn it, expand it, or shrink it, the circle remains essentially the same.
Every circle you can imagine is the exact image of every other circle there is.
This is not true of other shapes. A rectangle may be short or tall. An ellipse may be fat or slim. A triangle may be squat, or stand upright, or lean off at a drunken angle. But circles are all the same, except for magnification. A circle three inches across is a perfect, point-for-point copy of a circle three miles across, or three millimeters.
What makes a circle so special and beautiful? Any child will tell you, what makes a circle is its roundness. Perfectly smooth and plump, but not too fat.
The definition of a circle is “all the points at a certain distance from the center.” Can you see why this definition forces absolute symmetry, with no pointy sides or bumped-out curves?
One way to express that perfect roundness in numbers is to compare it to the distance across. How many times would you have to walk back and forth across the middle of the circle to make the same distance as one trip around?
The ratio is the same for every circle, no matter which direction you walk.
That’s pi!
Puzzles with Pi
For all ages:
Sarah Carter created this fun variation on the classic Four 4s puzzle for Pi Day:
Using only the digits 3, 1, 4 once in each calculation, how many numbers can you make?
You can use any math you know: add, subtract, multiply, square roots, factorials, etc. You can concatenate the digits, putting them together to make a two-digit or three-digit number.
1. Imagine the Earth as a perfect sphere with a long rope tightly wrapped around the equator. Then increase the length of the rope by 10 feet, and magically lift it off the Earth to float above the equator. Will an ant be able to squeeze under the rope without touching it? What about a cat? A person?
2. If you ride a bicycle over a puddle of water, the wheels will leave wet marks on the road. Obviously, each wheel leaves a periodic pattern. How the two patterns are related? Do they overlap? Does their relative position depend on the length of the puddle? The bicycle? The size of the wheels?
3. Draw a semicircle. Along its diameter draw smaller semicircles (not necessarily the same size) that touch each other. Because there are no spaces in between, the sum of the diameters of the small semicircles must equal the diameter of the large one. What about their perimeter, the sum of their arc lengths?
4. Choose any smallish number N. How can you cut a circular shape into N parts of equal area with lines of equal lengths, using only a straight-edge and compass? Hint: The lines don’t have to be straight.
To everyone who has supported my Tabletop Math Games Collection Kickstarter project: thank you ever so much! We’ve blown past our funding target and the first two Stretch Goals. And the Kickstarter folks awarded us the “Project We Love” tag. 😻

Math games build mental flexibility and strategic reasoning in players of all ages. And even people who hated math in school can enjoy the friendly challenge of a game.
I love how the challenge of a well-fought math game pushes players of all ages to think more creatively and build fluency.
Games Promote Mathematical Thinking
Math games push students to develop a creatively logical approach to solving problems. In the stress-free struggle of a game, players learn to analyze situations and draw conclusions.
Even more importantly, games help children learn to enjoy the challenge of thinking hard. Their vocabulary grows as they discuss options and strategies with their fellow players. With their attention focused on their next move, they don’t notice how much they are learning.
And games are good medicine for math anxiety. Everyone knows it takes time to master the fine points of a game, so players can get stuck or make mistakes without losing face.
What’s Special About These New Books?
Readers of my Math You Can Play series know the joy of gaming can transform a child’s attitude toward math. But many of you tell me the books get lost on your bookshelves or in your ebook reading device. You’ve begged me to make math gaming more open-and-go.
So my new Tabletop Math Games Collection is designed to make it easier than ever for busy families and over-stressed teachers to play with math.
These books are written directly for young gamers and require only common household supplies like cards, dice, and scratch paper. Children can open to any page and start playing right away.
Not to mention the swag! I’m excited about the items we’ve created to go along with the books. The “Gaming in the Enchanted Forest” coloring page by fantasy artist Tanya Hales is absolutely delightful, and the enamel pins are a fun and colorful way to share your playful math joy.
