Identifying and Writing Fractions  A fraction tells about the parts of a whole or a set.  The number on the top of the fraction represents the shaded part of the whole. It is called the numerator.  The number on the bottom represents the total number of equal parts in the whole. It is called the denominator. 1 = red shaded part ___ 3 = total number of circles 1 = green part 2 = total parts 1 = yellow part ___ 4 = total equal parts

Comparing Fractions If you were really hungry would you rather have 1/4 of a pizza or 1/2? 1/2 of course! Would you rather have 1/2 or 2/4 of a pizza? They’re the same, silly! When the numerators are the same, the smaller the denominator, the larger the fraction. When the numerators are different, use a picture, fraction bars or other manipulative to help you compare. The same fractions can have more than one name. These are called Equivalent Fractions.
