Order of operations and solving for variables can be fun! This product allows students in grades four through seven to stretch themselves by completing task cards for both order of operations and for solving variable equations. After that, short assessments of both skills are included. Finally, students are asked to create a set of twelve equations for the class to solve, and it must include an answer key. Each task card and assessment included in this product has an answer key. Print out the activities for one or more of your students who would like a challenge. Enjoy!
