Students are introduced to some esoteric number categories as they check out the various descriptors of this year's date.  What's a Harshad number?  What's a Pernicious number? What's a tetrahedral number?

While checking out the number they practice reducing fractions, reviewing bases, using formulas, and verbally explaining a visual arrangement.
