## Reflection: Developing a Conceptual Understanding Imaginary Numbers Day 2 of 2 - Section 4: Homework

One theme across the Common Core mathematics curriculum is having multiple models to solve problems.  I have tried to support and extend this in Algebra 2.  I do not require that students use a specific method to solve a problem.  Rather, I offer multiple methods either through modeling or student volunteers and allow my students to use what works for them.  This assignment is an excellent example of this idea.  During the notes, my students worked to develop a conceptual understanding of the modular nature of imaginary numbers.  I then allowed them to use the method that made the most sense. Some students divided the numbers and used the remainder like in this sample Student Work.  Others followed the circular model we developed during class Notes.  I even had students make lists of fours or tick marks.
