## Sketch a Graph Activity

I created this Sketch a Graph Activity to give my Algebra 2 students much-needed practice with the vocabulary we use to describe the key features of functions. This activity was based off of a problem in Pearson’s (now Savvas) Algebra 2 textbook. Even though the alignment of the textbook to the Oklahoma standards has left …

## Inequality and Interval Notation Chart

Just a quick post today to share an inequality and interval notation chart I created for my Algebra 2 students this past year. Due to COVID, I did not do my normal style of note-taking style in my classes this year. We were asked to do things with as little paper as possible due to …

## Graphing Inequalities Dry Erase Work Mat

I created this graphing inequalities work mat when I taught Algebra 1 to help my students conceptualize what it actually meant to graph an inequality. So often, I have a tendency to just give my students a set of steps to follow without making sure they understand why we are following those steps. Why are …

## Key Features of Functions Work Mat

I created this Key Features of Functions Work Mat to use with my Algebra 2 students during our introductory functions unit. We used it to practice concepts including domain, range, increasing and decreasing intervals, positive and negative intervals, and x- and y-intercepts. I printed the Key Features of Functions Work Mats on 11 x 17 …

## Translating Algebra Around the Room Activity

The last year I taught Algebra 1, I put a humongous emphasis on translating between words and algebraic symbols. I created this Translating Algebra Around the Room Activity to give my students extra practice translating expressions, equations, and inequalities. This activity is structured in such a way to emphasize that there is not one correct …

## Slope Treasure Hunt Activity

When I taught Algebra 1, I ran across a fun slope treasure hunt activity for practicing the concept of slope (or gradient, for my international readers). My Algebra 1 students really enjoyed this slope treasure hunt. The activity is appropriate for middle school math as well. I originally came across this Slope Treasure Hunt (also …

## Paper Folding a Hyperbola

Back in February, I learned how to use paper folding to create an ellipse. Since then, I’ve wanted to try my hand at paper folding a hyperbola as well. It’s taken a few months, but I finally did it! Previously, I have bogged about paper folding both parabolas and ellipses. I learned about folding a …

## X Puzzles Factoring Review Game

I love using X Puzzles to introduce factoring quadratics. These puzzles are also known as sum and product puzzles since the goal of the puzzle is to find the two numbers that have a given sum and product. Years ago, I found a set of 5 pages of X Puzzles. I can no longer find …

## Real Number System Card Activity

I created this set of real number system cards several years ago to give my Pre-Calculus students much-needed practice determining which subsets of the real number system a number belongs to. This was one of our first lessons of the year, and it was a great exercise in understanding definitions, practicing mathematical precision, and using …

## Like Radicals Card Sort Activity

I created this like radicals card sort activity a few years ago when I was still teaching Algebra 1. Students are given 25 cards featuring radicals that range from square roots to fourth roots. Some of the radicals are simplified. Others need to be simplified. Students must group the cards into piles of “like radicals.” …
