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 …

# Domain and Range Activities

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 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

Here are the domain and range foldables I created for my Algebra 1 students to glue in their interactive notebooks. I use the DIXI ROYD mnemonic device to help students remember the difference between domain and range. DIXI ROYD Foldables for Domain and Range We made a DIXI ROYD foldable to remind ourselves of the …

I created this domain and range foldable for my Algebra 2 students. This foldable focuses on finding the domain and range of rational and radical functions. We glued the resulting foldable in our interactive notebooks as a reference. Free Download of Algebra 2 Domain and Range Foldable

In the past, my students have always done a good job of finding domain and range from a table or set of ordered pairs in Algebra 1. Hello, domain is the set of all x-values and range is the set of all y-values. Write them in squiggly brackets without repeating, and you’re done. They would …

I want to share a domain and range graphic organizer I created for my Algebra 1 students to glue in their interactive notebooks. I used the same DIXROY mnemonic device with my Algebra 1 students that I introduced to my Algebra 2 students. I don’t really know how many students even use this to help …

I used the same cards that we used for Domain and Range Pictionary to create an interactive domain and range foldable for my Algebra 2 classes. There are 32 cards which give my students 32 opportunities to practice finding the domain and range! We made a tiny envelope to hold our 32 cards. Let me …

This year I’m trying the DIX ROY acronym to hopefully help my Algebra 2 students remember the difference between domain and range! D – DomainI – InputsX – X-Coordinates R – RangeO – OutputsY – Y-Coordinates Last year, my students had a TERRIBLE time remembering the difference between domain and range. This summer, at the …

We started our Describing Graphs Unit in Algebra 2 by playing some domain and range pictionary. I used the domain and range graphing cards from Zero-Knowledge Proofs. I gave each student two pages of cards to cut apart and keep in their notebook. My students were surprisingly impressed by the small pocket we created to …

Tomorrow, my Algebra 2 class will begin identifying the domain and range of a function from a graph. I created a domain and range foldable to help my students keep the three different notations separate. I used a basic three door foldable. The first flap contains all of the information about set notation. The second …
