You can add text by using the Multimedia task. By adding text, you can provide instructions for your students, or any other information you would want students to pay close attention to.
To add text, open an existing Multimedia task or create a new one. An editing box will appear, where you can type in text as desired.
You can also modify text by using the left side buttons of the control bar.
For text size, there are 4 different options: Heading 1, Heading 2, Heading 3, and Normal. You can also bold and italicize text.
