I wonder how many books are in the whole school

The short answer... too many to count.

Look around and you will see buckets of books, shelves of books and stacks of books!

Take a look at this bookshelf in Ms. Rands' classroom.

The top shelf alone has 195 books on it.

Here is a number that I can give you. There are 15,634 books in the library.

That is 156 hundred flats, 3 ten longs, and 4 ones cubes.
