Get ready to set the standard! Pupils watch a video on how to graph a parabola from a quadratic in standard form without converting the form. Scholars learn how to find the axis of symmetry from the equation and from there the vertex. They continue to practice graphing 11 quadratics from standard form on the activity.

Concepts

Instructional Ideas

• Have individuals discuss the benefits of graphing using standard and vertex forms

Classroom Considerations

• The class should be able to evaluate a function at a given value
• Third lesson in a quadratics unit with five parts

Pros

• Highlights an error that is made when using a calculator to evaluate a quadratic
• Contains an additional set of problems for extra practice

Cons

• None
