Description: 
Gives students an introduction to number theory by emphasizing the significance of starting with containers of different parity, as compared to containers of the same parity. Some implied work with modular arithmetic, i.e. using the 3 oz. and 8 oz. containers, whenever one fills up the 8 oz. with the 3 oz., 1 oz. will be left in the 3 oz. container because 8 is congruent to 2 (mod 3). Questions encourage students to find a pattern involving parity.
