Module 8 Integers

In this module, you will define what is an integer and learn how to add, subtract, multiply and divide integers.  If needed, a review of addition, subtraction, multiplication and division of whole numbers can be used.  

You will be using number lines and counters to learn why integer operations work.  Then, after understanding why, you will be able to fluently solve integer problems.

Integers are the building blocks for advanced math concepts found in finance, computer science, and science to name a few.  For example, in finance you can use both positive and negative integers to discuss credits and debits.  A student might study positively and negatively charged particles in science or even play a round of golf and shoot "under par."  The list goes on and on about where integers can be used in everyday life.

Upon completion of this module, you will be able to:

1. Define and understand an integer.
   
2. Use number lines and counters to solve addition, subtraction, multiplication and division of integers.
   
3. Develop the sign rules of integers for multiplication and division.
4. Work with the closure property of integers.
5. Be able to connect the current Louisiana Students Standards, and NCTM standards to course content.

To achieve these objectives:

1. Read the sections below and work the embedded exercises within them.
2. Complete MyOpenMath homework for this module.
3. Complete the discussion forum for this module.
