Here is the interactive notebook page I created for my Algebra 2 students over solving quadratics by factoring. I typed up the Zero-Product Property for students to cut out and glue in their notebooks. In the future, I’d probably type up the steps as well to save time. I might make them fill in …

# Quadratics

One of my favorite ways to help students to memorize the quadratic formula is to lead them in quadratic formula songs. Here are several different songs I have used with students in Algebra 2. Emily Freeman shared several versions of the quadratic formula song with me. I already knew the Pop Goes the Weasel version …

I was inspired by Journal Wizard to create a Quadratic Formula Tangram Puzzle for my Algebra 2 students to glue in their interactive notebooks. To create the tangram puzzle, I printed a tangram square, wrote my message on top, cut the puzzle apart, and copied the pieces for my students to cut apart and glue …

I created this completing the square graphic organizer for my Algebra 2 students to glue in their interactive notebooks after we explored completing the square with algebra tiles. This student obviously did not pay attention when we were completing the square. I guess he did complete the square, but… To illustrate completing the square, I …

I got a chance to experience the constant chair regression activity at a common core workshop that I attended (OGAP) during the summer of 2013. I have never seen this activity posted anywhere online, so I am not sure of the original source. I am blogging about the activities that we worked through in an …

I worked through the How Tall is Harold? quadratics task from CPM’s Algebra 2 Connections Curriculum at a 2013 Common Core Workshop I attended (OGAP). I am blogging about the activities we did last summer so that they are easier for me to find when I go to plan lessons. I hope these ideas will …

I want to highlight this factoring polynomials square puzzle shared by Public Schools of North Carolina in their Resources for Algebra Blackline Masters collection (page 2 of PDF). The file no longer exists online, but an archived version still exists due to the Internet Archive. These square puzzles are often known as “Tarsia puzzles.” Make …

Today I’m sharing the interactive notebook page my students created to summarize solving quadratics by square roots. Solving quadratic equations by square roots is one of my students’ favorite ways to solve quadratic equations. I covered solving by square roots after solving by factoring. Since my Algebra 2 students still struggle with factoring fluently, solving …

My Algebra 2 students created this different forms of a quadratic function foldable to glue in their interactive notebooks. For the first day of this lesson, we created the foldable and wrote the names and formulas for each form of a quadratic function on the outside. We didn’t take any notes on the inside of …

Here’s an overview of how to play the flyswatter game to practice identifying the different forms of a quadratic function. The flyswatter game is one of my favorite games for classification practice. We played this game in conjunction with creating our Different Forms of a Quadratic Function Foldable. I’ve blogged more in depth about the …

We created this interactive notebook page for solving quadratics by graphing using the TI-Nspire. We glued this in our INBs after our Frayer Model for the phrase “Solve A Quadratic Equation.” This year, I am using the TI-Nspire graphing calculators with my Algebra 2 students. As someone who was trained to use a TI-84 …

My Algebra 2 class created this discriminant foldable in their interactive notebooks after they had already memorized and practiced applying the quadratic formula. I instructed them to open their notebooks to page 72 and title the page “The Discriminant Is Our Friend!” Of course, a student asked me if I am racist. Ahem. The discriminant …

I’m excited to introduce you to wax paper parabolas! This year, my Algebra 2 interactive notebooks are easily a hundred times better than last year’s Algebra 2 notebooks! I’m serious. Last year, I did a pretty good job with Algebra 1. And, Algebra 2 sort of got the short end of the stick. …

Today I want to share some graphic organizers I created to remind students the steps for factoring quadratics. We filled these out and glued them in our algebra interactive notebooks. This year, I am taking a big risk with my Algebra 1 kiddos. I taught them to factor quadratic trinomials with a leading coefficient greater …

I created this methods of factoring foldable for my Algebra 2 interactive notebook.

Today I’m sharing a factoring flow chart that has been really helpful to my students. Factoring finally clicked for my college algebra students. It was definitely a Hallelujah! moment. The lowest grade on the factoring test was a 95. I’m definitely not your typical math teacher. When students ask for help during a test, I …
