Directions for activity:
- Print on bright paper and post the 8 problems around the classroom or another contained space in the school.
- Working with a partner or two, students start at any one of the 8 problems.
- When they get their answer, they should be able to find it on another paper. They go to that problem next.
- If they do all 8 correctly, they should end up back where they started. If they don't see their answer on a paper, or if they repeat an answer, they know something went wrong, and they need to revise.
Every problem asks students to find all zeros of a polynomial function. Imaginary/complex and irrational roots are included. There are many ways students can approach each problem, and they could pull from the following skills to help them solve:
- Rational root theorem
- Synthetic or long division
- Conjugate pairs
- Quadratic formula
- Descartes rule of signs
It is a PDF. The answer key is built in because the papers are in the correct order in the file. (Thus, you will need to randomize the order when you hang them around the room.)
