How to Complete the Response Grid

1. Work the problem and find the answer.
2. Write your answer in the answer boxes at the top
   of the grid.

• Print your answer with the first digit in the
  left answer box. Do NOT leave a blank answer box
  in the middle of an answer.

• Be sure to write a decimal point or fraction
  bar in the answer box if it is a part of the
  answer.

25
How to Complete the Response Grids

1. Fill in a bubble under each box in which you
   wrote your answer.

• Fill in one and ONLY one bubble for each box.
  
• Do NOT fill in a bubble under an unused box.

• Fill each bubble by making a solid black mark
• that completely fills the circle.

• You MUST fill in the bubbles accurately
  to receive credit for your answer.

26
How to complete a negative grid

• No numbers are placed in the 1st column.
• If the answer is not negative, Do NOT bubble in
  the 1st column. Leave it blank.
• If the answer is negative, print only a negative
  sign in the 1st column. After the 1st column fill
  in a bubble under each box in which you wrote
  your answer.
• Fill in one and ONLY one bubble for each box.
• Do NOT fill in a bubble under an unused box.
• Fill each bubble by making a solid black mark
• that completely fills the circle.
• You MUST fill in the bubbles accurately to
  receive credit for your answer.

27
Simplifying and Rounding Issues

• Simplifying--- We recommend
• Do not simplify fractions UNLESS the directions
  tell you to simplify to lowest terms OR if the
  answer doesnt fit in the grid unless you
  simplify it.
• Rounding--- We recommend
• Dont round UNLESS the directions tell you to
  do so.

Summary of Common Gridding Mistakes

• Adding extra zeros
• Bubbling more than one number in a column
• Adding unnecessary spaces
• Forgetting to bubble
• Omitting the decimal point
• Gridding mixed numbers incorrectly
• Gridding percents incorrectly
• Adding extra symbols outside/inside of the grid
• When using negative grids, writing a number in
  the 1st column
