# INSTRUCTIONS

Rename to Higher Terms uses number lines to demonstrate how a fraction can be renamed to higher terms.

The following equivalent fractions were made from Rename to Higher Terms:

When the program starts, you will be shown two fractions. The fractions are equivalent, but both the numerator and denominator of the second fraction are in higher terms.

The example shows that the first fraction will not change in value if the numerator and denominator are multiplied by the same number. In the above image, both the numerator and denominator are multiplied by 4.

Although we chose a multiplier,4 we are multiplying the fraction by 44 , a form of one. One (1) is called the multiplicative identity because multiplying a number by one or some form of one does not change the value of the number.

You can input a fraction less than one and a multiplier less than 100. Both terms of the fraction you enter will be multiplied by the multiplier to show the fraction in higher terms.

On the left is a <SHOW COLOR> button. Uncheck the button to turn off the arrows and the red and blue parts on the number lines. This will allow the learner to demonstrate the size of the fraction.

Uncheck the <EXPLAIN> check box to turn off the answer and the explanation. You can ask your students to complete the number sentence.

With <EXPLAIN> and <SHOW INPUT> unchecked you can ask your students to write a number sentence that explains the picture.

With <EXPLAIN> and <SHOW COLOR> unchecked you can ask your students to shade the indicated fraction and write in higher terms.

Suggestions:

Turn color and explain off and demonstrate how much of each number line should be shaded. Then write the fraction in higher terms.

Keep the first fraction the same size, but increase the size of the multiplier. Observe that there are more parts, but the parts are smaller.

Emphasize that if you select 4 for a multiplier, you are not multiplying by 4, but by 44 , a form of one. One (1) is the identity for multiplication. A fraction multiplied by one(1) or a form of one results in an equivalent fraction.
