Free Solving Quadratic Equations by Quadratic Formula lesson


Copy of FREE Solving Quadratic Equations

The joy of delicious food and family time is quickly approaching with the holidays!  It’s a great time of year to share more math classroom resources with fellow Algebra 2 teachers.

I really enjoy teaching Algebra 2!  It can be a challenging class to teach because the students that take the course spans a wide range of levels of interest and levels of understanding.  I often find that Algebra 2 gets its groove right around second quarter when students are back into the swing of school.  My students know it is going to be a rigorous year but a good one.  We’ve overcome some challenges already and they are ready to commit to the work they need to do to learn!   They know I am going to support them and help them learn all that they need to know by the end of the year.

I find it so fun to watch how each Algebra 2 class likes to solve quadratic equations.  Some classes prefer solving quadratic equations by completing the square, while others like factoring.  This year my students have really learned to love the quadratic formula because “it can solve any equation”.  I love that they appreciate this about the quadratic formula and that they are recognizing which methods are appropriate and best to use in different situations.

It’s important to me that my students know that the quadratic formula isn’t just a magical phenomenon that gets us the solutions, but that it is a result of solving ax^2 + bx + c = 0 for x.  It’s a challenging task but working through it together empowers students to better understand mathematics and how it works.  Not only do I want my students to be able to do math, I want them to think and understand it!
