Scrambled Eggs is an assessment strategy that is applicable to ALL content areas and grade levels. This free resource has a teacher's instructions page as well as a projectable instruction page for students. You will want to thoroughly explain the instructions to students before starting.
From my experience, it is best to use this strategy at the end of a unit of study to act as review for students.
**Please note that this strategy is very much kinesthetic. Your classroom will likely be noisy if students are engaged.
