Functions

The Silent Board Game is a strategy to help students practice finding and writing the rule for a function. I was introduced to the silent board game strategy at a session on “Fun Functions: Active and Interesting Function Activities” hosted by CPM at the 2016 Summer Conference of the Oklahoma Council of Teachers of Mathematics. …

Decorate your classroom with this collection of printable parent function posters. Your students will appreciate being able to reference this visual reminder of 13 of the different functions they will learn about in their algebra and precalculus courses.

Just a quick blog post today to share a set and interval notation dry erase template I ran across recently while organizing my Algebra 2 files. I didn’t actually end up using this dry erase template because the other activities I had planned ended up taking a lot longer than usual. My plan, though, was …

One of the yearly activities I look forward to at my school is our annual Pinwheels for Peace celebration. Pinwheels for Peace is a school-wide, cross-curricular project that occurs every September. At my school, the project is headed up by by my super-talented, award-winning art teacher neighbor, Shelley Self. September 21st is International Day of …

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 …

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 …

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 …

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 …

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 …

I created this find the flubs activity to give my Algebra 2 students some extra practice with set notation and interval notation as well as number lines. This was the perfect review before beginning domain and range!

I created this set of 12 basic functions posters to accompany the 12 Basic Functions Challenge Activity for my Pre-Calculus Classes. I decided the posters deserve a page of their own so they can be more easily found and downloaded. Each one of these posters represented one of the 12 basic functions identified in our …

I’m here today to share some Roots Solutions Zeros X-Intercepts Posters. Yes, that is a mouthful. Yesterday, I started doing some serious planning for teaching Algebra 2 in less than a month! I’m at a new school that has adopted new textbooks, and I’m not exactly the biggest fan of the chosen Algebra 2 book. …

I updated my domain and range restrictions foldable from last year to update some of the examples. Free Download of Domain and Range Restrictions Foldable

I borrowed these domain and range foldables from Math by the Mountain. You can learn more about her relations and functions unit in this blog post. Domain and Range of Discrete Relations Foldable Domain and Range of Continuous Relations

I took my trusty DIXI ROYD mnemonic and turned it into a domain and range graphic organizer for my Algebra 1 students to glue in their interactive notebooks. Free Download of Domain and Range Graphic Organizer DIXI ROYD

I created this independent vs dependent variables foldable for my Algebra 1 students to glue in their interactive notebooks. Since I started teaching, I have struggled to teach independent and dependent variables in a way I am proud of. Each year, it seems like I try something new. And, no matter what, the same 60% …

My go-to for introducing the concept of a function is a function frayer model! Free Download of Function Frayer Model

I created this function notation puzzler to help introduce my Algebra 1 students to the concept of function notation. Historically, this has been a very tricky topic to teach in Algebra 1. When I originally made this activity, I didn’t think it all the way through. All of the values I picked as my examples …

I created these evaluating functions from a table notes for my Algebra 1 students to put in their interactive notebooks. Another big change I made this year was introducing evaluating functions by only looking at graphs and tables FIRST. Once my students were comfortable with evaluating this way, then I introduced evaluating from an equation. …

I created these evaluating functions from a graph notes for my Algebra 1 students to glue in their interactive notebooks. Another big change I made this year was introducing evaluating functions by only looking at graphs and tables FIRST. Once my students were comfortable with evaluating this way, then I introduced evaluating from an equation. …

I created this graphing functions using input/output tables foldable for my Algebra 1 students to put in their interactive notebooks. After graphing the “Win Some Cash!” functions, we did some more graphing functions practice.  After graphing each function, students had to classify the function as linear, absolute value, quadratic, or exponential. We needed lots of …

I created this writing functions foldable to give my Algebra 1 students practice both writing functions and using them to solve problems. My students found these problems to be a bit difficult. I think we should have spent more time practicing these than we did. Free Download of Writing Functions Foldable

This popcorn graphs activity is one of my favorite ways to practice writing stories for graphs with my Algebra 1 students. I love graphing stories! This was my second time using popcorn graphs with my students. The conversations were awesome this year as well! Though, because I teach teenagers, I had to stop one of …

I created this graphing stories foldable for my Algebra 1 students to glue in their interactive notebooks. I was a bit short on time, so I just ended up using the same graphing stories foldable as last year. Here are close-ups of the two tasks inside. I found both of these tasks online. The problems …
