"The element of play, which makes recreational mathematics 'recreational', may take many forms: a puzzle to be solved, a competitive game, a magic trick, paradox, fallacy, or simply mathematics with any sort of curious or amusing fillip.... Perhaps this need for play is behind even pure mathematics. There is not much difference between the delight a novice experiences in cracking a clever brain teaser and the delight a mathematician experiences in mastering a more advanced problem. Both look on beauty bare -- that clean, sharply defined, mysterious, entrancing order that underlies all structure."
Martin Gardner (1914-2010), father of recreational mathematics

G4G Celebration of MindAnnual World Events
Celebration of Mind events bring people of all ages together to share and delight in playing with puzzles, games, math and magic. As Martin Gardner said, you can learn more when you’re in a state of entrancement and that’s our guiding principle.
Large and small, formal and informal, CoM events are happening around the world.
Need help planning your event? We have a growing list of resources including puzzles, games, magic tricks, illusions and crafts that are free to download and use. We also have a list of talented presenters who are happy to enliven your CoM event.

No longer updated but contains a wealth of 'timeless' resources for math circles
A math circle is a social structure where participants engage in the depths and intricacies of mathematical thinking, propagate the culture of doing mathematics, and create knowledge. To reach these goals, participants partake in problem-solving, mathematical modeling, the practice of art, and philosophical discourse. Some circles involve competition, others do not; all promote camaraderie. wikipedia

Players use a common pool of cards (each containing math operations and a number) to create an equation that equals a target number. For the basic game, the target number for the first player is 1, for the secon player 2, etc. The player that solves the highest value target number is the winner. The game can be differentiated for K-12 by including/excluding various operations, e.g. addition, multiplcation, factorials, exponents).

Got It! + ‘Math Geek’ Expansionby Tom Jolly
Ages: 6+2-8 players, 30 mins.
A 6x6 grid of cards is placed randomly checkerboard-style on the table with numbers (1-14) and mathematical operators adjacent to one another. Everyone plays simultaneously, with players trying to find a five-card formula that results in the number shown on a goal card (ranging from 1-40). The solution must consist of horizontal or vertically adjacent cards, though not necessarily in a straight line. Players can mentally insert parentheses into a formula.
An easier version of Got It! can be set up for younger players, with a 5x5 grid that contains only the numbers 1-9 and only addition and subtraction as math operators.

A math game highlighting the power of the prime numbers. Each player controls two pawns that start at the 0 circle. Players take turns rolling two 10-sided dice and applying the values to their two pawns using any of the four basic arithmetic operations: addition, subtraction, multiplication, and division. The first to get both pawns into the 101 circle exactly wins the game! The color coding allows players a way to quickly analyze the factors and multiples of the numbers on the board.

EQUATIONSAccelerated Learning Foundation
Forty years of research and testing have extended the range of this joyful learning tool to become the centerpiece of the Instructional Gaming Program in schools.
Research demonstrates that EQUATIONS develops skills far beyond “drill and practice” computation. It cultivates the critical problem-solving abilities needed to recognize and apply fundamental concepts. It creates a rich problem-solving interaction filled with complex strategy, bluffing and intrigue. The basic game can be taught to eight-year olds using simple arithmetic. As players develop skill, the game becomes more sophisticated exploring a broad range of math topics: addition, subtraction, multiplication, division, exponentiation, root operations, logarithms, fractions, decimals, percents, variables, algebra, functions.

Each of these 21 “kits” is an individual EQUATIONS match designed to teach one powerful concept dealing with the fundamental relationships between the arithmetic operations (addition, subtraction, multiplication, exponentiation, and root operation). The pamphlet responds to all possible moves that the user can make in a manner that focuses the match on the targeted idea. IMP Kits are useful for home or class situations where computers are not always available.

REAL NUMBERSAccelerated Learning Foundation
REAL NUMBERS is a game that involves rolling 5 'math dice' (numbers 0-9, +, -, /, *, root, and exponentiation). The roller of the dice then declares a type of number: natural, integer, rational, irrational, real.Players (or teams) then come up with as many solutions (values) as possible by combining the dice faces that were rolled (within the constraints of the declared criterion). One point is scored for each correct answer and one is deducted for each incorrect answer. A bonus is earned by declaring and successfully defending claim that one has found all possible solutions.

Napier's BonesCreative Crafthouse
Invented in 1617 by John Napier, this device is referred to as the ‘first calculator’ and was in common use for nearly 300 years. This set of rods was capable of doing long division and square roots.
Genaille-Lucas Rods for MultiplicationCreative Crafthouse
In 1891 Henri Genaille invented these rods as an improvement to Napier’s Bones/ These rods allowed the user to read off the results of simple multiplicaiton problems with no mental calculations.
The Irrational PuzzleMathArtFun
Four cubes are dissected in 4 different ways to form 11 geometric solids. The puzzle introduces students to the concept of irrational numbers and the Pythagorean Theorem.
ITSPHUN: Geometric Construction Kit - Pologons
A 104-piece system (36 triangles, 36 square, 12 pentagons, 20 hexagons) of interlocking shapes that can be used to create free form creations or the ones specified on 28-double-sided cards.
Pythagorean Theorem PuzzleCreative Crafthouse
Use the provided pieces (4 triangles of sides a-b-c, 4 squares of size 'a', 'b', 'c', and 'a-b') to prove the Pythagorean theorem. The documentation provides 3 ways.

Created over 100 years ago by the children's author, Peter Newell, these are cartoons that appear as something else when turned 'upside down' (hence the different captions on the top & bottom of each page.
Martin Gardner mentions these books. They are important for illustrating 'pictoral' symmetry and for creating intellectual empathy -- the realization that different people looking at the same things from different perspectives can have justifiably different interpretations.
It is tragic that so many mistaught students and their teachers subscribe to the notion that the defining virtue of math is that there is one and only one correct answer to every problem. Compiance-centered instruction aimed at passing end-of-year multiple choice tests reinforces this untruth.
"Topsys and Turvys" and the "Illusions" sections are good, playful pedagogical experiences for developing intellectual empathy & humility that are important attitudes for critical thinking (whether applied to math, science, civic life, or oral/written communication).
