=Steps of Model Drawing =
 * 1) Read the problem.
 * 2) Identify the "who" of the problem.
 * 3) Identify the "what" of the problem.
 * 4) Draw unit bars of equal length for each "what".
 * 5) Reread the problem. Underline each key component and log the information onto your visual representation.
 * 6) <span style="color: #000000; font-family: 'Comic Sans MS',cursive; font-size: 138%;">Place the question mark in the correct place on the visual representation.
 * 7) <span style="color: #000000; font-family: 'Comic Sans MS',cursive; font-size: 138%;">Compute the problem.
