V OCABULARY : Proper Fraction : a number that stands for part of something. Why use a fraction?  to name a part of one thing ( a fraction of a whole )  to name part of a collection of things ( a fraction of a set )

3 4 = the number of parts = the total number of equal parts in one whole, or a set P ARTS OF A F RACTION

3 4 = numerator: how many parts being talked about = denominator: the total number of equal parts

A CTIVITY Creating Equivalent Fractions

A CTIVITY Create an Equivalent Fraction Counting Books. Using the Fractions; ½ 1/3 ¼ 1/5 1/6 create a page for each. Each page can be divided into two sections one with the original fraction and the other side containing the equivalent fraction. Each page should include pictures, words and numbers.
