### Math Activities with BOOKSHELVES

Bookshelves--they're everywhere--in homes, libraries, bookstores, classrooms, and sometimes even bus-stops!  What do they have to do with math?  Here's some ways you can play with math and bookshelves...

• Pick a particular bookshelf to work with...
• Measure it (Height, width, depth)
• What is the cubic measurement of the inside? (volume)
• What is the perimeter (outside) measurement?
• How many shelves does it have? (counting)
• Pick a shelf to count and multiply it by the amount of shelves--Will that give you the approximate total?
• Observing the books on your bookshelf...
• If you had to share your bookshelf evenly between a certain amount of people (maybe your family members) how many would everyone have? (Addition, division)
• How many different colors of book covers are contained on your bookshelf?  Make a chart to sort them.
• How many genres of books are in your bookshelf? (Sorting)
• Find the average number of pages for one particular genre.
• Map out bookshelves at a bookstore or library and label them by section. (Mapping)--This could be a whole class activity.
• How many bookshelves were in the each section (fiction, cooking, etc)?  You could have different children work on the different sections to help map out the whole bookstore or library.
• Take one bookshelf and calculate how much that shelf of books would cost to buy every book.  (Multiplication)  You can estimate \$10 a book if that is easiest.
• If every kid in your class had some dollar amount--maybe \$50, could you all buy one bookshelf?
• How many books could everyone buy? (Division)
• What percentage of the bookshelf is that?
• Other ideas...
• Find out how many bookshelves could fit in one room of your house--two versions--1.) fit on the square footage (floor) of the room and 2.) fit in the cubic area of the room. (Addition, multiplication, division, volume, measurements)
