## Celebrate Pi Day!

March 14 is National Pi Day! Make your plans now to celebrate math with Pi Day using some of these neat resources, books, and ideas. We have links to tons of websites with activity suggestions for all grades. We also have a list of books that you can read and follow up with notebooking pages or lapbooks.

In my family, we have started out our day with headbands. On the front of the headband we attached a triangle resembling a slice of pizza pie or a circle resembling a whole pie. The kids colored in their favorite pizza or pie. Then wrote the word "Pi", underneath that "3.14", then "(the pi symbol)." We wore our headbands for the rest of the day, so that whenever we looked at one another, the "visual" learners had a reminder of Pi throughout the day.

We read a variety of stories involving the use of measuring a circle and all its measurements. At the same time, we happened to be studying ancient Egypt, so that we were reading a book about Archimedes at the time. Here is a list of books that relate to the study of Pi:

**Sir Cumference and Dragon of Pi**by Cindy Neuschwander**Sir Cumference and the Isle of Immeter**(diameter of a circle) by Cindy Neuschwander**Sir Cumference and the First Round Table**(circles) by Cindy Neuschwander**Sir Cumference and the Sword in the Cone**(cone's dimensions) by Cindy Neuschwander**Archimedes and the Door of Science**by Jeanne Bendick (the chapters near the end of the book look at Archimedes' mathematical studies)- Piece of Pi: Wit-sharpening, Brain-bruising, Number-Crunching Activities with Pi by Naila Bokhari (activity book)
**The Joy of Pi**by David Blatner (middle to high school range)**A History of Pi**by Petr Beckmann (high school) (reference to million years old earth on first page)

Part of our day we read books, writing a notebook page summarizing what we learned about Pi on the bottom half of a notebook page and on the top half, drawing diagrams and examples of using Pi in a formula. My younger son had a worksheet with a table to fill in as he measured the circumference, diameter, and radius of objects around the house. My older son had a similar table to complete, but had an extra column where he had to use Pi to calculate the different dimensions of various circular objects around the house. Some Pi activity worksheets can be found at EnchantedLearning.com and EdHelper.com.

Go to NoteBookingPages.com and obtain different notebooking pages to write your findings of Pi.

If you want to have your kids do a Pi lapbook, join Live and Learn Press's Yahoo group and receive a free wonderful lapbook at LiveandLearnpress.com.

Other families have members compete with one another of who can memorize the most digits of Pi and keep a record in the days leading up to March 14th.

You can end your Pi Day celebration like we did, by making a pizza (or ordering one) and taking its measurements using the formula. Enjoy your day making memories no one will forget!
