Integers+and+Order+of+Operations

During the month of October we studied Integers and the Order of Operations. Integers are positive whole numbers and their opposites. Students studied real life examples of negative numbers, including temperature and depth below sea level. By the end of the unit, students were able to add, subtract multiply and divide integers.

Students also learned about the Order of Operations. This is the order in which mathematical operations must always be performed. A good memory tool is PEMDAS: But be careful! Multiply and Divide are a pair. You do these things from left to right. Add and Subtract are another left to right pair.
