In this interactive document, students learn the steps of the process of completing the square for both quadratic equations and functions. Questions and generated randomly at two levels of difficulty. This activity is written using Lua and is displayed in both English and Arabic.

Students should have some experience of solving single step quadratic equations. Some work on solving by factoring may also be suitable.

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.

Students should continue with further work on solving quadratics and explore applications, such as quadratic inequalities and transformations.
