### I'm piggybacking here off of a post from Sarah Carter. I loved the question stack cards Sarah created for her students to practice evaluating expressions. However, my eighth graders hadn't reviewed operations with integers yet, so I wanted a more basic set of cards that didn't include negative numbers so that I could check that my students had the process down for substitution and following the order of operations to evaluate. Sarah does a great job explaining how the question stack works…
