The Geometric Effect of Some Complex Arithmetic 1

Translating complex numbers is as simple as adding 1, 2, 3. In the ninth lesson in a 32-part series, the class takes a deeper look at the geometric effect of adding and subtracting complex numbers. The resource leads pupils into what it takes to reflect across the real and complex axis. By the end, class members can determine the complex number to use to arrive at a desired translation.

Instructional Ideas
  • Conduct a quick review of translations, reflections, and rotations on the coordinate plane
  • Use a projection device or interactive board to show the transformations that occur while operating with complex numbers
Classroom Considerations
  • The class should be familiar with using the Pythagorean theorem
Pros
  • The resource includes a lesson summary that lists the concepts the class should have learned
  • The exercises, examples, exit ticket, and problem set all contain similar problems
Cons
  • None
