The Bible of Math and the Cal Ripkens

Conor kneels before his bible--a Grade 4 math workbook.  He bought this on his own, by his request,  with his own money, and does it for fun.  Craziness.  (Forget word problems, I don't even make change.)

All under the watchful eye, of course, of the autographed jersey of his holiness Baltimore Oriole Cal Ripken Jr.

Conor calls the Baltimore Orioles the "Cal Ripkens".  As in, what's your favorite baseball team, Conor?  The Cal Ripkens.

Behold, the workbook.
