Quadratics have three major forms; standard, vertex, and factored form. Each has advantages and can be used to find different attributes of a quadratic equation or function. Each can also be used to model real world applications. Activities will include using algebra tiles to help with the process of completing the square and using the three forms in different ways and applications.
