Equivalent Fractions
Objective: Students will be able to write equivalent fractions and mixed numbers.We will model them, multiply and divide them, as well as reduce them into simplest form by finding the G.C.F.

Definitions:
Equivalent Fractions: Fractions that may be written with different denominators, but equal the same amounts when simplified.
Simplest Form : is when both the numerator, and the denominator is reduced into greatest common factors.
Equivalent: means EQUAL
