Today we will identify fractions on a number line.

A number line and a ruler are very much alike

On a ruler, each inch is considered one whole inch One Inch Two Inches Three Inches Nine whole inches

The marks in between the whole inches are fractions of an inch ½ Inch 2 ¾ Inches 7 ¼ inches

Number lines are read the same way. The Numbers are read as whole numbers. The marks in between are read as fractions

There are three steps to reading fractions on a number line Step One- Start on the whole number and Jump to the next whole number. That is your denominator. Step Two- Jump, starting at the first whole number. Stop at the point you are naming. This is the Numerator

What fraction represents the letter A. B. 0 1 AB Step One- Start on the whole number and Jump to the next whole number. That is your denominator. Step Two- Jump, starting at the first whole number. Stop at the point you are naming. This is the Numerator.

There is only a step three if the fraction is past a whole number. Step One- Start on the whole number and Jump to the next whole number. That is your denominator. Step Two- Jump, starting at the first whole number. Stop at the point you are naming. This is the Numerator

Mixed number fractions Step One-Start on the whole number and Jump to the next whole number. That is your denominator

Mixed number fractions Step Two- Jump, starting at the first whole number. Stop at the point you are naming. This is the Numerator

Mixed number fractions Step Three- Write the whole number as a whole number beside the fraction

What fraction represents the letter A. B. 0 21B A Step One- Start on the whole number and Jump to the next whole number. That is your denominator. Step Two- Jump, starting at the first whole number. Stop at the point you are naming. This is the Numerator.

What fraction represents the letter A. B B A 5 3 A B ABA Step One- Start on the whole number and Jump to the next whole number. That is your denominator. Step Two- Jump, starting at the first whole number. Stop at the point you are naming. This is the Numerator.
