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 The file no longer exists online, but an archived version still exists due to the Internet Archive.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 …

# Quadratics

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 …
