Speed Counting to infinity

(MathPickle, 2010)

For one class teachers¬†should just count and count and count. There is no better way to show the relative size of numbers. Cheating after 200 is allowed ūüėČ

I now believe in starting really, really slowly. “One”¬†should take 30 seconds¬†to say. ¬†“Two”¬†should take about 25¬†seconds. By the time you get to 100, you are counting intelligibly. When you hit 200, start to speak intelligibly only for every tenth number… keep speeding up.

This is a vignette that all young students should experience. Get a visitor with some dramatic sensibility to come into your class to do it. That’s better than wasting your political capital on something so strange ūüėČ

There should be no such thing as boring mathematics.

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.
