This module is an introduction to the basics of fractions.            Module #1

Understanding fractions is a useful skill because

• Fractions are common in everyday life, from measuring in the wood shop to measuring sugar in the kitchen to finding a shooting percentage.
• Fractions come up in many settings and we often need to simplify them and put them into decimal or percent form. For example, if a baseball player has 56 hits in 160 at-bats, 56/160 = 7/20 = .350.
• It is important to understand how fractions work.
• Fractions are useful numbers for solving many problems.

 6-question Pre-Quiz (answers may be obtained from Dr. Olsen)

All exercises in this module should be done without using a calculator. To fully understand how fractions work you need to be able to do the operations by hand (on paper or mentally). Once the concepts and procedures are mastered, there will be times that calculator use is appropriate.
