Tribute to Eric Carl

(MathPickle, 2010)

Kindergarten students experience mathematical pattern and structure in many of their books. Some enjoy the predictive qualities of pattern. They like the rhythm of words and benefit from the repetition of meaningful phases.

“Brown Bear, Brown Bear, What do you see?” has a linear pattern – ending in a surprise. Think of the pattern of other children’s stories. “I know an old lady who swallowed a fly” is not linear. It would be better illustrated by concentric circles – with the little fly in the middle – caught by the spider – caught by the bird, cat, dog, goat, pig, cow, horse…

What about “The Enormous Turnip?

It’s clearly a budget. It’s got a lot of numbers in it.

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.
