Set and Interval Notation Dry Erase Template

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.

Set and Interval Notation Dry Erase Template

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 to give each student a copy of this template in a dry erase pocket. I would project either a set of numbers written in either set notation, interval notation, or a number line illustration. My students would copy down the example and fill in the other notations.

Hopefully someone can actually make use of this in their classroom!

This activity looks amazing. I wonder, do you have an answer key?
