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.

Added in 2021 a digital version to use with Google Slides!

Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.
Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.
