Intro to Primes & Composites
The way I introduce Prime and Composite numbers is through one of the engaging puzzles above. However, most educators make the mistake of starting with a formal, but not quite as engaging, structuring of the subject matter.
Engage first – structure later.
If you absolutely feel compelled to introduce the structure first, then I suggest something like that shown in the video on the left where prime and composite numbers are introduced using elastic bands and talk of rectangles, square and line-segments.
I think the universe is pure geometry – basically, a beautiful shape twisting around and dancing over space-time.
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.
