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/

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.

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.

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:
