A few days ago I foolheartedly wrote a post called "Learning About Domain and Range" that was all about the great domain and range learning that would soon be happening in my classroom. Eeeert, stop the record! Abandon ship! Abandon ship!

My plan today was to give this domain and range scavenger hunt to assess student understanding, but we're going to need a little more practice first. 
Seeing domain and range - especially range - of a graph is proving to be particularly difficult for my students this year. Assessing now didn't seem fair. To give a bit more practice before grades, I made these extra domain and range practice cards (free).

Students find the domain and range of each of 10 graphs. Then, they need to decide whether each graph is a function or not. This was also a good spiral review for function/not a function. 

I printed the cards you see in the picture on blue paper and set a stack on each student table to share. Each student got his or her own student answer sheet. I saw a lot of good work that made me really hopeful! I think their confidence improved, too.

Here is a short video showing students that we can use a pencil to identify domain and range of graphs. You can grab the domain and range sheet I'm using in the video as a reference here in my Google Drive. And the cards are here.

One fun, low-stress way to assess students is with math pennants. I get feedback everyday on how well they work with students and how teachers are using math pennants with their students. Ideas include: warm ups, centers, team building group work, exit tickets, and of course as classroom décor.  
The domain and range pennant above asks students to find domain and range when given scatter plots, tables, graphs, coordinate pairs and mappings.

This set of domain and range pennants are shaped like cornucopia for Thanksgiving. 

This domain and range mini-bundle includes a matching activity, a scavenger hunt and the non-holiday pennant. 

For classrooms with technology, I made this domain and range digital escape room. Students find the domain or range of each function representation and enter a 4-letter code to unlock each lock. 

What is your favorite way to teach, practice and review domain and range?
