Students shared what they learned in the quadratics video from yesterday - what a quadratic is and how to identify them. Then we used Desmos Polygraph Quadratics to ask questions and look at the differences between different types of quadratics (sort of like math Guess Who). We realized that we really need better vocabulary the ask really good questions about quadratics to distinguish them. Then we practiced graphing quadratics from a table and plugging in points. From there we identified two new things: the vertex and the axis of symmetry.
