The Pi Day Discovery Activity is a fun and festive way to celebrate Pi Day while practicing math skills. Students will measure the circumference and diameter of 5 round objects (supplied by the teacher or the students) and then calculate the ratio of circumference to diameter for each object. Students will then analyze the digits of Pi by creating a tally chart and a histogram to represent the frequency of the first 50 digits of Pi. Students will use the data and graph to identify patterns and draw conclusions about Pi. Finally, students demonstrate their understanding of Pi by creating a song, poem, story, etc.

This activity could be used for centers/stations:

•Station 1- Measure the circumference and diameter of 5 circular objects using a string and ruler or a measuring tape.

•Station 2- Using the first 50 digits of Pi (π), tally each time a digit occurs and then write the total amount of times each digit occurs. Create a histogram to represent the frequency of the first 50 digits of Pi (π).

•Station 3- Using the ratios of circumference to diameter of each of the five objects, identify a pattern that you notice. Next, explain how this ratio relates to Pi (π). Then, identify a typical (most likely occurring) digit of Pi (π). Finally, write a conclusion about Pi (π). Use evidence to support your assertions.

•Station 4- Learn more about Pi by exploring the resources provided. Take notes and explain your thinking about each note.

•Station 5- Create a song/rap, story, poem, pun, etc. that demonstrates at least two facts you learned about Pi (π).
