Define terminology related to a circle. Practice accuracy in measuring and then create a spreadsheet based on data collected from solving for parts of a circle. Groups can have fun analyzing their data as it relates to Pi.

In this algebra instructional activity, students ponder life's questions presented in several episodes of The Simpson's. They calculate the square root of 1 million and verify known facts concerning pi. There are 9 questions.

Students explore different size circles to discover the relationship between diameter and circumference. In this circles and Pi lesson, students construct simple parachutes using circle patterns of varying sizes. Students predict the...

In this factoring polynomials worksheet, 9th graders solve and complete 33 different multiple choice problems. First, they determine the equation that best represents a simplified form after factoring out the GCF. Then, students...

Third graders work in groups of two to three with measuring tapes, finding the circumference and diameter of teacher-selected circular items. They relate circumference and diameter measurements to find pi.

If you dropped a needle on a lined sheet of paper what is the probability that the needle will cross one of the lines on the page?  Surprise your class with how calculating this probability can approximate pi. This question is known...

Fifth graders explore geometry by exploring Pi. In this circle measurement instructional activity, 5th graders identify the relationship between the radius, diameter and circumference of a circle and how Pi is the key to unlocking any...

Sixth graders discover Pi.  In this discovering Pi lesson, 6th graders measure the diameter and circumference of various circular objects.  Students record their measurements in a table.  Students discuss how Pi relates to...

Ninth graders explore the concept of pi in preparation for developing a project for pi day. They examine direct variation, the history of pi, circle circumference and arc length, area and sector area and then consider how these concepts...

Eighth graders measure the circumference and the diameter of circular objects and record the measured values of the circumference and the diameter in a table. They then record their measurements in centimeters and use their data to...

Students discuss the sum of central angles and use string to create them on circles. They find the measure and length of both minor and major arcs. Students give examples of concentric, similar, and congruent circles and congruent arcs.

Students study graphing skills and compare and contrast data sets. They compute pi through the first 50-100 digits and create a bar graph showing the frequencies of specific digits.
