This lesson introduces the best method that I have seen for factoring trinomials in the form ax^2 + bx + c. Before learning this method, I had students factor these types of trinomials by grouping (sometimes referred to as the "a•c" method), or by trial and error. But many of my students get frustrated with these approaches. On the contrary, the method I use in this lesson, which I refer to as the "double play" method, is much more user friendly for students. Some of you may have seen this approach before, but this product gives students a step by step easy to follow explanation of this method as well as plenty of opportunity for practice. Once students have learned this approach, I guarantee you that they will have more success when factoring these types of trinomials, and they will quickly thank you for teaching it to them.
This 8 page product has a total of 10 problems in which students must factor a variety of trinomials with a > 1. Once students are done factoring, there is space provided for them to check their "answers" using the "box" or FOIL method. Problems #1 and #4 guide students step by step thorough this whole process.
