Follow these steps to practice changing the font in the practice document:

1. In the practice document, click and drag over the first sentence to highlight the entire sentence.  A shaded border appears around the text when it's selected.
2. Click the font menu on the toolbar - it is where you see 'Times New Roman'
3. Choose MORE FONTS - it's at the end of the list
4. When the list of fonts open, scroll down to the end and take a look at all the different fonts that are available.  Some of them are pretty cool. 
5. Choose a new font, anything for now. 
6. Click OK
7. The sentence that you had highlighted changes to the new font
