This pdf file contains 6 versions of problem sets. Each problem set contains 10 problems; 5 where students write the coordinates for points and 5 where students plot points. Their are 2 different sets per page to reduce copying costs. Each set has a small symbol so students do not easily know they are doing different work than their neighbor. Multiple versions are available for review, homework, quiz and make-up work or independent practice followed by discussion of work in groups. The six student versions are followed by the six versions with answers.
