Differentiated activity to review adding, subtracting, multiplying & dividing integers.
All students start at the bottom of the pyramid. The bottom level includes basic addition, subtraction, and absolute value expressions. The middle layer contains multiplication & division problems, including exponents. The top level is made up of multi-operation expressions involving order of operations with integers. The idea is that students can't move up to the next level until all problems are correct per level.
Below and on-level learners may never reach the top, and for more struggling learners, perhaps may never make it out of the bottom level. Some on-level and beyond grade-level learners will most likely complete the pyramid. I tell my students that the goal is NOT to finish, but to understand they problems that they do get done, and to answer as many questions as they possibly can.
This activity can be utilized in various ways most conducive to your classroom, for example in stations, as an "early finisher" activity, etc. I am usually walking around as students are working independently, checking problems as they go. I ask students to raise their hands when they need me to check their work. This allows me to provide immediate, individualized feedback while students work at their own pace; however, the possibilities are endless and the activity can be utilized in various ways as mentioned above.
