Product Description

These activities are a perfect way to teach your students all about pi as a irrational number while practicing important math skills of converting fractions, decimals and percentages. Included are three different activities that all look at the number frequency of digits 0-9 in the decimal digits of pi. Not only can you use these activities in a variety of ways including for math stations, small groups, homework, enrichment or even as extra credit, but they will make for a fun pi day celebration!

Activity #1: Investigating Number Frequency of Pi

In this activity your students will:

• Examine the first 100 digits of pi.
• Keep a tally of how often the digits 0 through 9 occur.
• Use their math skills to convert the tallies into fractions and percentages.
• Create a bar graph based on their results.
• Reflect on the activity by answering questions at the end of the activity.

Activity #2: Coloring the Digits of Pi

• This can be added on to the previous activity or would be perfect for a pi day optional challenge activity. Your students will create a key of colors representing digits 0-9. They will then use their key to color a 100 grid representing the first 100 digits of pi.
• You could have your students color multiple grids to represent the first 200, 300 or even 400 digits of pi. The best part is that these make a fun visual and classroom display!

Activity #3: Number Frequency Group Challenge

• In this activity, small groups of students will take on the task of analyzing the number frequency of digits 0-9 in the first 200, 300, 400 or even 500 digits (you choose as the teacher) of pi!
• They will follow the guidelines of the challenge by answering questions, completing the frequency table and creating a poster with their analysis (which includes a pie chart).
• Also included is a grading sheet.

• "Did this on Pi Day last year, and it was very neat to see the frequency charts displayed all together. Great resource."

• "Different than your typical Pi Day activity! Like it!"

• "My middle school students enjoyed this activity. Great to review fractions and percents along with graphing. Thanks!"

• "My students and I had a great time using this!"

• "Fun product and easy to incorporate into my PI day activities. Thanks!"
