INSTRUCTIONS
Add With Lines uses number lines to demonstrate addition of fractions.
You can unput the two addends for an addition of fractions example. The sum of the addends cannot exceed 6. Press the <OK> button and the circles fractions for the addends and the sum will appear.
Suggestions:
Start with adding like fractions such as 1 3/6 and 2 2/6. Then enter 1 1/2 and 2 1/3 to see how the common denominator of 6 is used.
Enter 5/6 and 5/6 to see how the mixed number 1 2/3 results. Then add 1 5/6 and 3 5/6 to see how the mixed number 5 2/3 results.
On the left is a <COLOR OFF> button. This button toggles with <COLOR ON>. Turning off the color turns off the red and blue addends on the sum number line. This will allow the teacher to ask the student to demonstrate the size of the fraction.
The <EXPLAIN OFF> button toggles with <EXPLAIN ON> Explain will show the two addends with a common denominator and the sum. Explain off will turn the explanation off, allowing the teacher or student to demonstrate how the sum is found.
