Fractions in Fewer Weeks

 

Welcome to your Fractions Unit!

This unit will explore fractions by comparing, adding, and subtracting. You will use a number of different strategies to complete these tasks.

The task for this unit will be the same as the previous unit on percentage. You will be given a number of tasks each week, which you will complete mostly independently.  On Mondays at 12:30, you will be given an opportunity to discuss any of the questions or problems you had on the previous week's material. 

You will be required to watch videos, complete online tasks, and textbook questions. You will also complete the unit with a test. 

 

Please follow the schedule outline in the Process section!

Good Luck!

 Introduction: (Review of Important Concepts)

1.: Mixed Numbers and Improper Fractions:

• Watch the following video:

• And practice this concept here:

2. Common Denominators: A common multiple of two or more denominators; for example, a common denominator for 2/3 and 3/6 would be any  multiple of 6.  If you use the least common multiple of denominators, the common denominator is called the least common denominator.
