This is a quick, small poster that I made for my middle school students who were still struggling with the rules for solving problems with integers. They were especially struggling with keeping the two sets separate in their heads, wanting to use the multiplication/division rules for everything. The poster prints on regular 8.5 x 11 paper.
--Extra note: I chose not to use the proper term (absolute value) on this poster due to the low language proficiency of my students. The second page contains a poster with this term.
