Domain and Range Intervention!

Teaching ideas for domain and range in special education algebra 2

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!

Domain and Range scavenger hunt

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.

Domain and range math pennant

Another 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 decor.  

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. 

Domain and range mini-bundle: matching, scavenger hunt, pennant

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

domain and range digital escape room

To meet the needs of 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?

I like the Domain and Range Task Cards, that will be a fun activity for kids and an easy tool to help them remember how to visualize and denote D and R. Nice!

Thanks! Seeing Domain and Range on a graph is the hardest for my students so this gave them a little extra practice on a Friday when motivation was at a week-low. HA! They were practicing without practicing:)

Thanks for sharing your experience as a reflective educator! Great example of adjusting plans in order to meet the needs of students.

Thanks for stopping by to read it! :)

Thanks for sharing, you have great stuff! I find that every year my group of students have different troubles than pervious years. It definitely keeps me on my toes!

ScaffoldedMath said...

Yes, this year especially for me. I swear if I break it down any further I'll be at the molecular level. But it's gotta happen and it's pushing me to be better! I love your stuff too! :)

This is a lifesaver! I have a Geometry brain and this year is my first time teaching Algebra, so I love these resources. Are your practice cards on TPT? The link from this page is dead, and I couldn't find them in your TPT store, but I'd love to use them!

ScaffoldedMath said...

I'm so sorry about that! I am not sure what was going on with the link, but it is all fixed now. Thank you for letting me know and congrats on the new job!

Dawn said...

Thank you so much for the cards!

ScaffoldedMath said...

My pleasure, Dawn! I hope they are helpful! :)

Unknown said...

This is amazing and very helpful. Thank you.

ScaffoldedMath said...

I'm so glad! I hope you are having a great week!

I think there may be a mistake on the answer key for the domain on #4 on the Domain and Range Practice Cards :)

Thank you! All fixed now. I really appreciate your help!
