### Gridded-Response and Set-Up Questions

There are ten non–multiple choice questions in the math portion of the GED. These questions require you to find an answer and to fill in circles on a grid or on a coordinate axis.

### Standard Grid-in Questions

When you are given a question with a grid like the one that follows, keep these guidelines in mind:

• First, write your answer in the blank boxes at the top of the grid. This will help keep you organized as you "grid in" the bubbles and ensure that you fill them out correctly.
• You can start in any column, but leave enough columns for your whole answer.
• You do not have to use all of the columns. If your answer takes up only two or three columns, leave the others blank.
• You can write your answer by using either fractions or decimals. For example, if your answer is , you can enter it as a fraction, 1/4, or as a decimal, .25.
• The slash (/) is used to signify the fraction bar of the fraction. The numerator should be bubbled to the left of the fraction bar and the denominator should be bubbled in to the right. See the example that follows.

• When your answer is a mixed number, it must be represented on the standard grid in the form of an improper fraction. For example, for the answer 1, grid in 5/4.
• When you are asked to plot a point on a coordinate grid like this one, simply fill in the bubble where the point should appear.

### Set-Up Questions

These questions measure your ability to recognize the correct procedure for solving a problem. These questions ask you to choose an expression that represents how to "set up" the problem.

Example: Samantha makes \$24,000 per year at a new job. Which expression shows how much she earns per month?

1. \$24,000 + 12
2. \$24,000 – 12
3. \$24,000 × 12
4. \$24,000 ÷ 12
5. 12 ÷ \$24,000

The answer is choice d. You know there are 12 months in a year. To find Samantha's monthly income, you would divide the total (\$24,000) by the number of months (12). Choice e is incorrect because it means 12 is divided by \$24,000.

### Graphics

At least 25 out of the 50 questions on the GED Mathematics Exam use diagrams, pie charts, graphs, tables, and other visual stimuli as references. Sometimes, more than one of these questions will be grouped under a single graphic. Do not let this confuse you. Learn to recognize question sets by reading both the questions and the directions carefully.

### What's Specific for the GED?

The structure of the GED Mathematics Exam, revised in 2002, ensures that no more than two questions should include "not enough information is given" as a correct answer choice. Given this fact, it is important for you to pay attention to how many times you select this answer choice. If you find yourself selecting the "not enough information is given" for the third time, be sure to check the other questions for which you have selected this choice because one of them must be incorrect.

Additionally, the current GED has an increased focus on "math in everyday life." This is emphasized by allowing the use of a calculator on Part I as well as by an increased emphasis on data analysis and statistics. As a result, gridded-response questions and item sets are more common. The number of item sets varies.
