Want your Trigonometry or PreCalculus students to practice computing arc length and area of sectors? This incredibly engaging and fun group puzzle will give your students practice determining the length of an arc and area of sectors in circles using a given central angle and radius!
To begin the activity, place students in small groups (the ideal number is 6 to a group, but group size can be modified as needed!). Each group member will work on one of the six puzzles in this resource. Once all six individual puzzles have been completed, students will work together to assemble the larger puzzle. Please see the preview for step-by-step instructions on how to assemble both the individual puzzles and the larger, collaborative puzzle (pictures included!).
Completed puzzles can be hung on classroom bulletin boards, in the hallway, up on the wall, or from the ceiling. They create a great visual for anyone walking into or by your classroom!
This collaborative activity was created for a high school PreCalculus class or a high school Trigonometry class. Angles in this activity are given in both degrees and radians and students are asked to round their answers to the nearest hundredth (no
answers are left in terms of pi). Additionally, the pi button on the calculator was used to generate all answers, so your students will need to use that when completing these problems.
- 6 unique puzzles
- Student worksheet (so they can show their work)
- Puzzle Template (so they can glue their individual puzzle pieces down before putting together the larger puzzle)
Materials You Need to Provide (or Students Need to Bring):
