Get Your Students Hired
Using money to hold your audience captive is one way of keeping students interested in math. Before you do this however, it is sometimes neccessary to give a pep talk. Ask students to put past feeling about math aside and ask them to take the subject on as "a new challenge " . Encourage them to be in it to win. Find out what peaks each student interest (what excites them) and incorporate your findings in building your math examples.
Good Luck!
