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!
Process
Week 1: Introduction: (Review of Important Concepts)
1. Equivalent Fractions: fractions that are equal in value. For example the fractions 1/2 and 2/4 are equivalent because they represent the same value.
- Watch the following video and complete the appropiate activities:

- Test your knowledge of equivalent fractions by playing this game:

2. Lowest Terms: An equivalent form of a fractions with a numerator and denominator that have no common factors other than 1. For example: 3/4 is the lowest term form of 12/16 since 3/4=12/16 and 3 and 4 have no common factors other than 1.

4. 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.
