Title: As if numbers weren't complex enough already!
Description: After years of being told that they couldn't take the square root of a negative number, you introduced your students to imaginary numbers. And, now, you have the nerve to expect them to go eagerly into the world of complex numbers? This lesson will introduce students to performing operations with complex numbers.
Note: This lesson is deisgned to be completed as a computer lab activity utilizing both small and whole group instruction.
This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.

Title: Who am I? Find A Polynomial From Its Roots
Description: Students analyze the roots and end behavior of a polynomials and write the equation of a polynomial under given conditions. Students apply theorems concerning the multiplicity of roots, conjugates of irrational or complex imaginary roots to find a polynomial under given conditions. Students will factor polynomials to find the complex roots. Students graph polynomials and determine the local extrema. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
