## Writing Quadratic Equations Card Sort

###### By Lisa on October 9, 2017 at 12:16 pm

While working with having learners write quadratic equations, I found they were having difficulty even getting to the equation. One of the things that surprised me the most was how much difficulty learners had in translating what I would consider basic phrases (find two consecutive integers when the smaller number squared increased by three times the larger number is 47, for example). I put together a card sort with various types of situations that would result in setting up a quadratic equation and then learners would have find the correct equation and then solve the equation. None of these problems are looking for a maximum or minimum (i.e. the vertex). I realize that many of these problems may be considered pseudo-context, but they were what I could find to get close to what I thought the standards were looking for. This card sort was designed to work with the following Common Core State Standards: A.CED.1 Create equations and inequalities in […]
