Students are given a model for completing the square for quadratic expressions for which the coefficient of the x^2 term is 1. Repeated mini-whiteboard practice and an exercise follow. Students are then shown how to use the completed square to find the turning point before tackling a scaffolded exercise. Finding the turning point for graphs where the coefficient of the x^2 term is -1.
Students are given models for completeing the square and finding the turning point for when the coefficient of the x^2 term is (i) a square number and (ii) any number.
