Fractions

Käsekuchen

A man is like a fraction whose numerator is what he is and whose denominator is what he thinks of himself. The larger the denominator, the smaller the fraction.

—Leo Tolstoy

 

The “Pies Per Child[1]” approach to fractions used in this part comes from James Tanton, and is used with his permission. See his development of these and other ideas at http://gdaymath.com/.
