Do some interpretive modeling. Class members watch three examples of interpreting key features of a graph of a quadratic to find solutions to a real-world problem. Learners review how to find the key features on a graph using technology...

It looks different, but yet the same. Scholars view a video that introduces them to the vertex form for a quadratic equation. Pupils realize that though the equation looks different, its graph is still a parabola, and the key features...

Apply polynomial multiplication to area. The short video in a large series shows the process of creating a polynomial formula for the area of a rectangle. Using the two expressions for the length and width of a rectangle, pupils see how...

Don't be bored to death when learning about quadratics. Using a given quadratic equation representing the number of deaths per year per thousand people in terms of age, scholars determine the number of deaths for a particular age group....

Video solving an application problem by finding a quadratic equation to represent the distance of a diver above the water based on his time in the air by determining his average velocity. Equation is solved using the quadratic formula....

Video solving an optimization application problem by finding a quadratic equation to represent the profit for a given product based on its selling price. Problem is solved by finding the selling price that gives a maximum value for the...
