Tables, tables, tables
Have more layout control over your pages, text boxes and wikis by using the "insert table" feature. Table looks too small when you add it to the page? Don't worry it will stretch to fit as you add text and images. Extra Tip: Right-click on the table to add more rows and columns.

Survey their understanding
Use the survey tool to assess knowledge of a subject area. An instant and
visual response to answers. The class can also see, instantly, how they have
all voted/answered. It also allows answers to be discussed without pupils
feeling as if they got it wrong.

Get you message across
Use a wiki to create communication that is easier to dip in to and can highlight key points.
