The 6th grade class is selling raffle tickets at a price of $6 for 5 tickets. Some students may use diagrams with shapes to represent the
situation. For example, here is a diagram representing 10 tickets for $12.

Drawing so many shapes becomes impractical. Double number line
diagrams are easier to work with. The one below represents the price in
dollars for different numbers of raffle tickets all sold at the same rate of
$12 for 10 tickets.
