## Build a Function Activity

I created this short and sweet build a function activity to give my Algebra 2 students extra practice using some of our new vocabulary: domain, codomain, and range. This activity was designed to accompany Section 1.2 (Introduction to Functions) of Shaun Carter’s Full Year of Algebra 2 Notes. I will be honest. Even though I …

## Folding Conic Sections Project

I decided to use this folding conic sections project to kick off our conics unit in Pre-Calculus. Over the last few years, I have learned how to create parabolas, ellipses, and hyperbolas using paper folding. I decided that if I could figure out a way to create a circle using paper folding that I would …

## Exponent Rules Match-Up Activity

I ran across this exponent rules match-up activity in the Algebra Activities Instructor’s Resource Binder from Maria Andersen. It was published by Cengage in 2011. I thought it would make the perfect review activity for exponent rules for my Algebra 2 students. I did find a copy of the activity uploaded online (page 7 of …

## Building a Cone to Visualize Conic Sections

I love teaching conic sections, so I was super-excited to discover a set of instructions online for building a cone to help students visualize the four different types of conic sections. This made the perfect addition to our last unit of the year in Pre-Calculus – conics! Conics used to be a topic I taught …

## Speedy Squares Activity for Quadratic Regression

I was so excited to discover this Speedy Squares Activity for practicing quadratic regression several years ago. I have used it successfully with my Algebra 2 classes in the past. Sadly, regression is one of the topics we did not get to fully explore in Algebra 2 this past year due to losing so much …

## Set Notation Puzzles

I created this set of four set notation puzzles to give my Algebra 2 students practice with set notation. I sadly didn’t end up getting to use them this year due to COVID restrictions. Each of the sets puzzles features a half-sheet of paper with four sets (A, B, C, and D). There are 15 …

## Order of Operations Question Stack Activity

I created this order of operations question stack activity to give my Algebra 1 students extra practice applying the order of operations to some rather involved expressions. These order of operations questions are specially designed to expose students to various grouping symbols including parentheses, brackets, absolute value bars, radicals, and fraction bars. I created a …

## Dry Erase Template for Solving Equations Graphically

I created this dry erase template for my Algebra 2 students to use while learning to solve equations graphically using our graphing calculators. The idea is that students will write the equation at the top of the page. Then, they will put each side of the equation into their graphing calculator. I provided students with …

## Domain and Range Challenge Activity

I created this set of 20 domain and range challenges for my Algebra 1 students to work though as a review for our quiz over domain and range. This post is yet another of my catch-up posts. I have been going through my old twitter posts to make sure that everything that I have tweeted …

## Finding Rate of Change from a Graph Hole Punch Activity

I created this hole punch activity to give my Algebra 1 students practice finding rate of change from a graph. When I teach Algebra 1, I intentionally avoid using the word “slope” for as long as possible. I printed off a bunch of practice questions for students to complete inside our dry erase pockets. If …

I really like this lovely radicals task from Terry Stickels. It simply asks: Which of the following is the smallest? I shared it on twitter, and I loved reading through people’s logical reasoning as they worked through the problem! I found this problem in The Big Book of Mind-Bending Puzzles by Terry Stickels.

## Leveled Practice Cards Activity for Absolute Value Equations

I created these leveled practice cards for solving absolute value equations when I taught Algebra 1. There are three levels of problems so that students can start with problems of an appropriate difficulty level. Level 1 Questions – Absolute value bars are already isolated. Level 2 Questions – Students have one step to do in …

## Exponent Rules Review Game with ACT Questions and Distractors

I created this exponent rules review game in February of 2020. It exposes students to actual ACT questions from past released exams, and it gives students a chance to play the role of exam writer by crafting tricky distractors for each question. I originally crafted this review game for my Pre-Calculus students. I wanted to …

## 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.” …

## Swap Two – A Logarithms Task

Harry O’Malley shares a lovely logarithms task called “Swap Two.” The expression below has three digits. Swap the position of two of the digits to make an expression with: 1) the highest value or 2) the lowest value.

## Area Model for Teaching Distributive Property and Factoring

NCTM Illuminations has an excellent PDF based resource on using the area model to teach both the distributive property and factoring out the greatest common factor. I used this resource frequently during the six years I taught Algebra 1. One year, several of my students really appreciated this structure for working out their problems. I …
