This is the first in a progression of Weekly Review Problem Sets. In my class I call them "Weekly Workouts" because I use the analogy of workout and making your brain stronger. The problems are review standards from previous years and the 7th grade standards as we come across them during the school year.
Each row is a different review standard. Within a row there are three different levels. You could assign different students or classes different levels based on their abilities. Another option would be to allow the student to choose the level that they can work at to successfully complete the problem. This allows students to feel success and want to try more difficult levels.
