ABSTRACT
Many students struggle with simplifying expressions with several operations because they do not understand that they are actually writing equivalent expressions as they conduct each operation. Some students benefit from using a graphic organizer that lists the operations in the order they should be calculated, line by line. Once all students have the hopscotch diagram at their tables, the teacher projects an expression on the board. After an allotted period of time, the teacher asks three volunteers for the final expression and records it on the board. The students correctly follow the order of operations but makes errors calculating with negative numbers.
