More Parts by Tedd Arnold

A boy is struggling to hold himself together as he learns that his heart is breaking, he can give someone his hand, he can crack up, hold his tongue (and possibly drop it) and more.  Finally, his parents help calm him down and explain things.  And everything is find until he finds out he can lose his mind.

Can You Count to a Google by Robert E. Wells

Wow, that's EXPENSIVE on Amazon today.  Best Price is $112.50.  I would NOT recommend spending that much on a book.  It's really good but not that good. 

OK, well, this one can go along well with How Big is a Million.  Expanding on the million idea, it takes you a bit further and explores a google.  Its written in the same style as How Do You Lift a Lion and Is a Blue Whale the Biggest Thing There Is?

How Big is a Million by Anna Milbourne

Pipkin the penguin wants to know how much a million is.  So, he searches to find things that are big.  He finds, 1, 10, 100, 1000 and more, but he has trouble finding a million.  Finally, in a fold-out poster at the end, his mother shows him a million of something.  Great for illustrating how huge a million really is.
