I like your product on systems of inequalities, you have some good pictures, consider putting a thumbnail to make it more attractive. I am new to TPT, check out my store
Did this activity with my algebra 2 class today and it went great! I actually made a document that had the graphs printed on it already for the students to fold around. If you would like this document, please let me know and I will email it to you or post it on my site.
