Teacher leads a discussion using the "Hints" buttons in the template to talk students through the logistics of how to assess the usefulness of a source.
Then, the class reads through a key source.
Half of the class are asked to make notes on "How Much" the source tells them; the other half make notes on "How Reliable" the source is.
These ideas are then fed back into a classroom discussion. The teacher should make notes in the appropriate cell of the template, which should be displayed on a projector screen / interactive whiteboard.
Finally, each student should provide a written answer to the question: "How useful is this source?" using the ideas in the template.
