Pi Day activity for math class! In this holiday-themed activity, students practice calculating area and circumference of circles. Students travel in pairs to eight stations as they practice solving problems involving circles, semi-circles, and quarter-circles. Practice problems range from very easy to challenging. Calculators are highly recommended due to some "unfriendly" numbers. Students will use 3.14 to represent pi and round answers to the nearest tenth. Students find the area or circumference of a circle given the radius or diameter, determine the area given the circumference and circumference given the area, and determine the area and/or perimeter of semi-circles and quarter-circles.
-You can either set up the 8 stations at groups of desks or tape the stations to the walls around the room. Either way keep the images that are alike together.
-Pair students up. Assign one partner to be “A” and one to be “B.” They should record their assignment in the top right hand corner of their workspace. (Differentiation note: Partner B will have slightly more difficult numbers to work with.)
-Students travel to each station as a pair. They each complete one problem based on their letter assignment. Although they are each solving a different problem, they can check to see if they are correct because they should have matching answers.
-Students neatly copy the original problem and show their work in the stations workspace.
-Once they complete their problem and confirm their answer matches their partner’s answer, then they check the key to find the answer and write the corresponding letter in the small box in the right hand corner of the workspace. The list of answers in the key represents both correct answers and answers that correspond to common mathematical errors.
-Students continue to go to all 8 stations. You can either allow students to move freely around the room in any order or set a timer and have students all rotate at the same time. Each station should take about 2-3 minutes.
-In the end, they should unscramble the letters to find the mystery word. They share this mystery word with you to confirm that their work is complete. The mystery word is EINSTEIN (since his birthday was on pi day!) I allow those students who finish first to help other students complete the activity.
