This product can be used as both an anchor chart and a process chart for students to follow when solving expressions using the order of operations. Two catch phrases are written on the chart to help students remember the order of operations (Purple Elephants May Destroy a School, and Please Excuse My Dear Aunt Sally). The operations are clearly written out in the form of a checklist/process chart. You can have students paste this into their math notebooks and they can actually check the boxes when they solve. Or, you can enlarge the chart and hang up in the room for students to reference. Or, do both :-) An example problem is also included on the chart. PDF file.
