In this interactive document, students explore the properties of complex numbers, from numeric through algebraic to graphical. Questions are generated randomly and all four operations with complex numbers are covered. This activity is written using Lua and displayed in both English and Arabic.
Before the Activity
Students should have some experience of solving single step quadratic equations. Some work on solving by factoring may also be suitable.
During the Activity
It is recommended that the teacher first demonstrate the steps involved in working through each part of the activity, and then allow students to continue at their own pace for as long as desired, either individually or in small groups.
After the Activity
Students should continue with further work on solving quadratics and explore applications, such as quadratic inequalities and transformations.
