Are complex numbers and binomials similar? This stack of slides provides an introduction to complex numbers and shows how to operate with them. The worked examples show a connection between operating with binomials and operating with complex numbers. It ends with a few examples of solving quadratics with complex solutions.

Instructional Ideas

• Many concepts are covered in this one presentation, consider splitting up the presentation over a few days with independent practice and guided practice problems provided after each major skill
• Develop a matching worksheet for the practice of the computation with complex numbers, such that problems with the same solutions would be matched

Classroom Considerations

• Many concepts are covered in the presentation; consider spreading out the presentation over a few days with independent and guided practice problems provided after each major skill

Pros

• Includes vocabulary, work-out solutions, and the step-by-step verbage for solving the problems

Cons

• Slide 15 appears to be missing information
• This is a PDF of slides, so there are no animations that would allow for steps of the solving process to be shown one at a time
