**Celebrate Pi Day** Happy 3.14159265358979323846264338327950288419716939... Day! = = = **Pi Quilts ** = Start with a 10 by 10 grid and have the students color in the squares starting in the center, spiraling outward. Each number has a different color above. Each student gets a different 100 digits of Pi, attach all the squares in the same fashion (center square is the first 100 digits, and then spiral the squares outward)

** Areas, Circles, and PI! **
//__OBJECT__//: To cover the most amount of area of a “game board” with a set number of different sized circles

Students work in pairs and each pair receives: Circle templates - 24 1” diameter circles - 12 2” diameter circles - 10 3” diameter circles - 8 4 ” diameter circles - 6 5 ” diameter circles <span style="font-family: 'Comic Sans MS',cursive;">- 4 6 ” diameter circles
 * <span style="font-family: 'Comic Sans MS',cursive;">Each sized circle is copied onto a different color*

<span style="font-family: 'Comic Sans MS',cursive;">Students work together in pairs, moving their circles around and trying different combinations to find a combination of different sized circles that cover the most area of their game board. Once they are satisfied with the arrangement, student will tape or glue the circles to the game board. Students are now to find the area of the game board which is NOT covered by circles. Students do so by measuring the diameter of each sized circle, finding the radius and using the formula A = πr2. They subtract the area of the circles from the original area of the game board. The student who has the smallest area wins a prize.

<span style="font-family: 'Comic Sans MS',cursive;">*Use colorful game boards and circles. Students make great patterns and the game boards are a nice display when all students are finished.

= Pi Activity for Math = Pi is the focus of this project. It includes a variety of activities to help you learn about You will discover the approximate value of Pi. You will use measurement and report data.

In the [|History] section you will be able to explore the history of using the World Wide Web.

In the [|Information/Video] section there are Fun Things About Kathleen Smith's award- winning hyperstack, "A Slice of Pi", and a video called "A Pizza Project on.

Materials:


 * measuring tape
 * string
 * ruler or meter stick

Objects to be measured:

 * juice can
 * soup can
 * coffee can
 * oatmeal box top
 * garbage can top
 * fruit can

Directions:
Use the measuring tape or the string and ruler/meter stick to measure the [|circumference] of the tops of the objects. Then measure the length of the [|diameter].

List these measurements in a table.


 * How does the measurement of the circumference compare to the measurement of the diameter? Is it twice as large? Is it three times as large or more than three times as large? This comparison is the ratio of the circumference to the diameter of the circle. This ratio is called Pi
 * In the column marked COMPARISON, list the answer for the circumference divided by the diameter.
 * The values we use for are 3.l4, 3.l4l6 or 3 l/7. If you would like to see the value of to 1000 places, click [|here]. Some other values of Pi that have been calculated can be found at [|History].

> ====Thoughts to Consider:====
 * Now take your values of Pi and round them to the nearest [|hundredth].
 * Compare your value to 3.14. Was your calculation greater or less than the 3.l4 value of Pi
 * Are the values of Pi onsistent? Why or why not?
 * What reasons do you think would account for these differences?

<span style="font-family: 'Comic Sans MS',cursive;">** Rolling for Pi ** <span style="font-family: 'Comic Sans MS',cursive;">Bring to class one or more large circular items such as abicycle wheel, hula hoop or plywood disc (available at many homeimprovement centers). Physically measure the circumference of your circularobject by marking the round item along the outside edge, and rolling it on thefloor one full revolution to convert the circumference into a straight line. Nextmeasure the diameter by finding the absolute widest measurement across thecircle. Lay the diameter measurement onto the circumference line and itshould go slightly more than three times. (Your results may vary slightly dueto measurement inaccuracies.)

Ask students to **compose an original song, poem, or piece of art** about Pi Day or the number pi. Hold presentations/exhibits, and present any artistic awards, on Pi Day. How about a "Pi-ku" poetry contest? (Think Haiku.) For example:

Unending digits... Why not keep it simple, like Twenty-two sevenths?

OR Write a poem in which each line corresponds to the number of syllables in  π — so, you would

have three syllables in the first line, one in the second, four in the third, one in the fourth and so

on.How many lines can you write?

Three point one four one five nine Makes the lazy student whine, But give this ratio a try You'll find that it's as easy as pi! I am a pious person I read the pi folklore And every week I memorize Just one digit more I simply cannot recognize The pattern in that string Of undecipherable words or worse- Simple random counting I cannot square a circle So how can I transcend The geniuses who came before? My quest will never end. But let me see just one more place Or find another use For this irrationality But why? I can't deduce.

<span style="font-family: 'Comic Sans MS',cursive;">** Pi Bracelets ** <span style="font-family: 'Comic Sans MS',cursive;">Inexpensive plastic beads twisted onto pipe cleaners or jewelry-making chains from the craft store

<span style="font-family: 'Comic Sans MS',cursive;">can be used to create mathematical bling!

<span style="font-family: 'Comic Sans MS',cursive;">What you need: <span style="font-family: 'Comic Sans MS',cursive;">Plastic beads <span style="font-family: 'Comic Sans MS',cursive;">Pipe cleaners, yarn or other product on which to string the beads

<span style="font-family: 'Comic Sans MS',cursive;">What you do: <span style="font-family: 'Comic Sans MS',cursive;">You will choose a color of bead to represent each number from 0 to 9. Thread the corresponding bead in the order of π to make a <span style="font-family: 'Comic Sans MS',cursive;">bracelet (on pipe cleaner) or a necklace (using yarn, etc.). Voila! Wearable math bling!

Use the site below and recite to a friend and record how many digits you memorized!

[] memorizing pie This is a web site that you simply type in the digits and it tells you how many digits you have correctly memorized and gives you the next 5 digits to study.

Using a LARGE piece of cardboard, cut out a circle and paint it colorfully (maybe even put a pi symbol in its center) Have the students estimate (guess) the number of centimeters its circumference is.
