People began to recall having looked at graphs of polynomials in Algebra 2 and some connections about a quadratic being a pretty simple polynomial were made. The fact that students can use a guess-and-check approach, however, means that everyone has a way of making progress. Why didn't I think of using an a!?!" Before long, someone realized we could use the power of algebra we had recalled earlier in the period and, after introducing an a, we soon had an expression for the "stretch factor" in terms of m and n. The excitement in the room once we added that coefficient and started moving the sliders was impressive. Before students do this activity, the idea is that they would have already been introduced to the graphs and started to identify characteristics of reciprocals of linear and quadratic functions. When we got to the screen showing the thumbnail view of everyone's graphs for the second of the intercept cases,  people were immediately intrigued by one graph that was not a parabola. Family of sin curves example. Working with World Data. Quadratic Regression on the TI-83. Guess the Distribution Desmos activity. You can also long-hold the colored icon and make the points draggable to see how their values change the equation. The equation can be defined in the form as a x 2 b x c. Get started with the video on the right then dive deeper with the resources and challenges below. ... Quadratic equations are mathematical functions where one of the x variables is squared, or taken to the second power like this: x2. I look forward to seeing how students do with the general "shifted-intercept form" case (where the points are , , and ) this weekend and to seeing what progress they make with the final case where they are given the y-intercept and two other points. All but one of my students sorted by the form of the equation - vertex and standard. After we admired it briefly, and talked about why it didn't meet the definition of a quadratic function, someone realized that we could turn the graph into a parabola if we just changed the exponent on from a 3 to a 1. Two posts from Dan Meyer help clarify: Culture Beats Curriculum and Real Work vs. Real World. To … … There was lots of, "Oh! It finally took them away from just seeing the form. ...

I also changed all of my students’ equations into regression equations, ... Quadratic Vertex Form Card Sort; I'm hopeful that having come to this insight this way will help students to see and more easily remember how they can go from the standard form of a quadratic equation to its graph without having to complete the square and without relying on having memorized that the x-coordinate of the vertex is (and students who think about this form of a quadratic equation carefully, can finally see why must be the x-coordinate of the vertex.). There are three ways to do this. This is a simple way to let students develop a pattern-based understanding of the connection between graphs and their algebraic representations before we agree on the formal rules of a new topic.
