Example 2:

1. After watching the videos and going over the example problems, then complete the practice problems and submit your work to me via email, title your email Week 2 Rational Numbers and then your name. 2. You will make 4 different number lines by using Microsoft Word. First you will make your paper horizontal by choosing page layout and landscape, next you will go to insert and shapes and choose a line with arrows on both ends to make a number line go across the whole width of your page, finally, you will choose shapes again and a line and place it directly in the center of your number line and label it 0. From there you can copy the line 3 different times and paste it on your page so that you have four number lines to work with. Now you are ready to place the numbers onto each line. All you have to do is choose shapes and line and put in a line for each place on your number line and then label what number the line stands for.
