It's National Library Week, when we honor those awesome people who let us borrow all the books we want and read to our heart's content. A library is a pretty amazing place: somehow, of the millions of books written over the centuries, a librarian has to choose a few hundred thousand to buy, then line them up really carefully so we can find them easily. Even with the "Dewey Decimal System," those number labels that tell you whether the book is about lions or spaceships, librarians still have to remember where the shelves are for those numbers!
Librarians seem to like numbers just as much as books: in just two weeks, hundreds of librarians have set up our Crazy 8s after-school math clubs that kids like you can join for free! To start a club in your town, check out this link: http://bedtimemath.org/crazy-8s-info/ In the meantime, let's run some numbers on the books.
Now here's todays math~

Wee ones: Which has more pages, a 14-page book or a 17-page book?
Little kids: If you take out 5 books from the library, return 2 of them, take out 3 more, then return 4, how many books do you still have at your house? Bonus: If the rest are due a week from Wednesday, April 16, when are they due?

Big kids: If of 200 kids' library books, half of them have 15 pages and half have 10 pages, how many pages do they have altogether? Bonus: How many would 200,000 books like that have?
Answers:
Wee ones: The 17-page book.
Little kids: 2 books left. Bonus: Wednesday, April 23.
Big kids: 2,500 pages. Bonus: 2,500,000 (2 million 5 hundred thousand), since it's 1,000 times as many.
