1.)Part one: Hands on
Materials needed for each group of 4 students: paper, pencil, centimeter ruler, various lengths of string, calculator, circular items (different sizes of lids), data collection worksheet. (See attachment Example:Data collection worksheet)
The students will work in groups measuring the circumference and diameter of at least 10 circular items. Students will record the measurements and then write and convert the ratio of the circumference to the diameter to a decimal rounded to the nearest 10 thousandths. (The number will be very close to pi.)After all calculations are done the student will compare answers with other groups. As a class we will calculate the mean of all the decimals. Again the answer will be very close to pi. Students will answer the 'Discovery' questions on the data collection worksheet. (duration: about 90 minutes)
2.)Part two: Students will use the data from the hands on activity to create an individual Excel spreadsheet.(See attachment Example:Excel spreadsheet Pi) (duration: about 90 minutes)
3.)Part three: Students will use the internet to research the history and other facts about pi. The students will create a microsoft word flyer advertising the 'Pi Times' celebration on March 14th. (See attachment Example Pi Times Celebration Flyer)
Students will include information from the data collection worksheet, excel spreadsheet and the research. Students will be required to document their research resources. (duration about 90 minutes)
4.)Part 4: Students will use the information from the Hands On activity, excel spreadsheet, research, and flyer to create a Pi Day powerpoint presentation. Criteria:
minimum of 7/maximum of 10 slides
minimum of 2/maximum of 7 graphics, photos or animations
minimum of 3/maximum of 7 Web links
minimum of 3/maximum 10 resources
minimum of 1/maximum of 2 sounds
optional  video clip
(duration: 90 minutes)
5.)Part 5: Assessment will be ongoing with expectations and criteria defined before each activity. (See attachments Example: rubric assessment for powerpoint, excel, flyer(word), and data collection)
