# IDENTIFY FRACTIONS INSTRUCTIONS

Identify with Number Line Models uses number lines to demonstrate the meaning of numerator and denominator.

The denominator tells the number of equal parts that make up a whole. The numerator tells the number of chosen parts. If you input 3 for the numerator and 4 for the denominator you will get a number line that is sectioned into 4 equal parts, 3 of them will be colored in (chosen).

You can input any fraction with a value less than 1. The denominator must be between 0 and 100. Press the <OK> button and the chosen fraction will appear.

On the left is a <SHOW COLOR> check box. Uncheck the box to turn off the arrow and the red selected part of the number line. This will allow the learner to select the fraction.

Uncheck the <EXPLAIN> check box to turn off the answer and the explanation.

With <SHOW INPUT> unchecked, the numerator and denominator input boxes will act the same as password input boxes so students will not see the numbers you input.

Suggestions:

Demonstrate numerator with 3/5 and then 4/5. This will show that the fraction will increase in size as the numerator increases.

Demonstrate denominator with 3/5 and then 3/6. This will show that the fraction decreases in size as the denominator increases.

With <EXPLAIN> and <SHOW INPUT> unchecked you have the opportunity to ask the student to name the numerator and denominator from the fraction model.
