This chapter will introduce you to several different strategies for teaching addition and subtraction of integers. I have found that breaking from the tradition of teaching addition/subtraction of integers first, then multiplication /division and teaching multiplication/division first, then addition and subtraction is a better approach. You will be given a visual of what addition of integers really means and why the sign of the answer is what it is. You will also be given a visual of what subtraction of integers really means and why the sign of the answer is what it is. Integers are presently taught in middle school, but I believe it would be more beneficial to teach integers immediately after division of whole numbers is taught. When it comes to addition/subtraction, keep your main goal in mind: Students should be able to add/subtract integers and determine the sign of the answer. No need to use extremely large numbers.

All students need a strong foundation in addition and subtraction of integers in order to be successful in upper level mathematics courses and in life.
