Use box # s on your grid paper. FCAT 2.0 Mathematics Reporting Categories Geometry and Measurement 0 Ratios/Proportional Relationships 2 7 Number: Base Ten 2 Statistics and Probability 20 What s different about these two boxes? 1

2 Should you line your answers up to the left or to the right? Gridding a Whole Number 27 + = or Gridding a Decimal Can you leave a blank box in the middle of your answer? or Can you fill in multiple bubbles for one box? What do you bubble in underneath a blank box? 2

3 Look at the negative grid below. Why is it not lined up all the way to the left? Is this correct? How to complete a negative grid No numbers are placed in the 1 st column. If the answer is not negative, Do NOT bubble in the 1 st column. Leave it blank. If the answer is negative, print only a negative sign in the 1 st column. After the 1 st column fill in a bubble under each box in which you wrote your answer. Using a Negative Grid Answer:-9.7 Correct Correct Using a Negative Grid Answer: 6.29 Correct Correct Incorrect or 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 doesn t fit in the grid unless you simplify it. Rounding--- We recommend: Don t round UNLESS the directions tell you to do so. How should we grid in this answer?

4 Gridding a Fraction / Be aware incorrect 6 1 / 4 You can NOT write a mixed number in an answer grid. If your answer is a mixed number y Ex: 6 1 you must 4 convert it to: / 4 or Gridding Percents What percent of 100 is 9? Gridding Percents What percent of 100 is 9? Answer: 9% 4

5 Gridding Percents What percent of 100 is 9? Answer: 9% incorrect incorrect Gridding Repeating Decimals.. Answer: / 100 Gridding Repeating Decimals.. Grid the answer Answer:. Correct Incorrect.. Grid the answer Four Minute Gridding Activity Correct % Use a pencil!

7 Copy Copy Equivalent ratiosare ratios that name the same comparison, or simplify to the same fraction. An equation stating that two ratios are equivalent is called a proportion. For example: Don t have to Copy If two ratios are equivalent, they are said to be proportional. Copy everything but the blue Example 1 Determine whether the ratios are proportional. Show your work in your notes do not copy the problem. Example 2 Use the data in the table to determine whether the ratios of oats to water are proportional for both servings of oatmeal. Copy everything but the blueexample Find a ratio equivalent to each ratio. Then use the ratios to write a proportion. Servings of Oatmeal Cups of Oats Cups of Water
