Students work in groups of four. In each relay, students will be assigned different roles. The first student decides whether the polynomial is a cubic that can be factored by grouping or a quartic in quadratic form. The paper is passed to the second student who completes the factoring. The third student receives the paper and double checks the factoring. They may multiply it back out or check for the difference of squares to factor further. The last student finds the zeros. There are imaginary solutions, as well as solutions that require rationalization.
Works Great For:
Students who are in a higher Algebra course and require scaffolding, based on performance or newly being introduced to the topic. It could also work well for younger students who are advanced in their factoring and solving skill set.
-Factoring cubic polynomials by grouping
-Factoring quartic polynomials in quadratic form
-Solving for zeros
