(MathPickle, 2011)

In the video I describe how to play Bracket with sticks, but you can also just download this pdf board. Each player would play with two markers.

You will need to come up with your own questions. They should be hard enough that an average person will have some idea about the answer, but could be out by a factor of 10. Email me your list of questions and I’ll give you credit.

PS. Bracket is one of my best game designs for the math classroom.  I have been looking for a publisher for over two decades, but perhaps it is just a little bit too logarithmic for the average household 😉

Standards for Mathematical Practice

MathPickle puzzle and game designs engage a wide spectrum of student abilities while targeting the following Standards for Mathematical Practice:

MP1 Toughen up!

This is problem solving where our students develop grit and resiliency in the face of nasty, thorny problems. It is the most sought after skill for our students.

MP3 Work together!

This is collaborative problem solving in which students discuss their strategies to solve a problem and identify missteps in a failed solution. MathPickle recommends pairing up students for all its puzzles.

MP6 Be precise!

This is where our students learn to communicate using precise terminology. MathPickle encourages students not only to use the precise terms of others, but to invent and rigorously define their own terms.

MP7 Be observant!

One of the things that the human brain does very well is identify pattern. We sometimes do this too well and identify patterns that don't really exist.


Please use MathPickle in your classrooms. If you have improvements to make, please contact us. We'll give you credit 😉
