You appreciate the beautiful puzzles on MathPickle.

In this puzzle grade two children shift ballast around the bottom of a boat so that the two sides balance. Not all puzzles are possible, however... some ships will sink!

Here is the link to Ballast addition:  https://mathpickle.com/project/ballast-puzzles/

Here is a link to Ballast multiplication for slightly older students:  https://mathpickle.com/project/ballast-multiplication/

Tip Jar - for engaging puzzles!

You appreciate the high fraction of students who stay engaged with MathPickle puzzles.  

In this puzzle, students are trying to help police organize their pin board. The solution shown is not good because the red string gets in the way of the faces. Coming up with a systematic way to represent a group of connected underworld characters prompts engaging mathematics.

Here is the link to the activity: https://mathpickle.com/project/pin-board-murders-patterns-angles-discussion/

Get MathPickle's puzzle mugs!

These mugs are taken from beautiful puzzles created or discovered since MathPickle first began in 2010. 

Picasso's line puzzles like the one you see on the mug require you to make brush strokes on a numbered canvas. For each stroke, the starting number times the length of the brush stroke must equal the final number. Try and fill up as much of the canvas as you can!

Supporter of the Scientific Method!

You might think that the best way to teach the scientific method is to send kids out into nature to get dirty. This is not true. The problem is that the laws governing the real world are complex. It is better to teach the scientific method in the math classroom with Mini Mathematical Universes whose laws are designed to be discovered.

The rainbow circle, pictured above, is an example of a Mini Mathematical Universe for the grade 4 classroom. Can you figure out what I was trying to do when I was creating it?

This puzzle won the George Pólya Award by the Mathematical Association of America. My co-authors were Kiran Kedlaya, and Henri Picciotto.

Benefactor of Unsolved Problems!

You understand that it's impossible to be a great mathematics teacher without teaching great mathematics.

Unfortunately, it is rare for elementary school teachers to be exposed to any of the pedagogic gems that masquerade as unsolved problems.

Of course, most unsolved problems are terrible in the classroom! For an unsolved problem to be a pedagogic gem, it must offer students lots of mini-successes along a path that starts out easy.

The #1 goal of MathPickle is to spread the joy of these pedagogic gems. Top students get inspired - struggling students practice their basic skills and see that everybody struggles.

The Graceful Tree Conjecture is one such problem. It belongs in all classrooms learning subtraction worldwide:

In the photo above you'll see four colors of hula hoop thrown about a gym in Hong Kong. The children are given two hula hoop colours that they are allowed to jump to. Some color combinations allow the children to jump from edge to edge of the gym while other combinations result in failure: https://mathpickle.com/?s=Hula+Hoop

Giving young students regular experiences of light-hearted failure is time well spent. Much better now than in first-year university!

What: I will send you a signed copy of Santorini and send you games that will fit with your family. 

Why: The number one way that parents can help their elementary school children in the mathematics classroom is to adopt a board game and try to beat their child at it every week. That's because the #1 objective of the mathematics classroom is to get children to problem solve and board games are a celebration of problem-solving.

When: Each week through the school year we will fix a time for me to zoom into a classroom or zoom group of your choice. 

Why is this going to be so good: Most of the problems will be my originals or adapted by me for classroom use. I'm passionate about this work, and with your input I will create something guaranteed to please.

The puzzle above is an example of a Mondrian Art Puzzle. They are easy to solve for a 4x4 or 5x5 canvas by average students, but even top students tackling an 11x11 canvas will probably not find the best solution.

Here are Mondrian Art Puzzles on Numberphile:

About Gord!

MATH PUZZLES
My best-known math puzzles have been featured in the New York Times, won the Mathematical Association of America's George Pólya Award, and been featured in both Ted-Ed and Numberphile videos.

https://ed.ted.com/lessons/can-you-solve-the-mondr...

These puzzles must be easy for teachers to use, enticing for students, and intrigue me. The objective is to achieve high classroom engagement in tough problem-solving.

All these creations are put up for free on MathPickle.com. It is a practical resource that thousands of teachers already use. 

CLASSROOM TESTING
I do not spend all of my time designing. I regularly teach students, mentor teachers and learn from both. This real-world testing keeps the ideas fresh and relevant. Take a look at the video for Half Fraction Snake below. You'll see it works well in the classroom.

https://youtu.be/h6iNTRyVIj0

UNSOLVED PROBLEMS
As well as puzzles and games, I also rework some unsolved problems from the last few centuries so they work in the classroom. Properly presented, these unsolved problems support the curriculum and engage the full spectrum of students. Top students are inspired... struggling students see that everyone struggles. Struggling is to be celebrated!

BOARD GAMES
When I'm not designing math puzzles for MathPickle I'm designing board games. My most famous is Santorini.

Puzzlingly yours,

Gord!
