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 exampe 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 4/4, a form of one.
You can input a fraction less than one and a multiplier less than 100. Both terms of the fraction you enter will be multplied by the multiplier to show the fraction 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 4/4, 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.
On the left is a <COLOR OFF> button. This button toggles with <COLOR ON>. Turning off the color turns 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.
The <EXPLAIN OFF> button toggles with <EXPLAIN ON> Explain will show how the higher term fraction is calculated. Explain off will turn the explanation off, allowing the teacher or learner to demonstrate how to write fractions in higher terms.
