In order to successfully complete questions involving number operations and number sense, students should be familiar with the meaning of numbers, number relationships, and the equivalent values for whole numbers, decimals, fractions, and integers. Students should understand place values and number properties. Students will be asked to identify the operation that should be used to solve a problem and to compute without the aid of a calculator. Students should be familiar with estimating to determine reasonable answers. Questions will also require students to analyze, explain, and apply ratios, percentages, and proportions.
Questions that involve data analysis, probability, and statistics will require students to perform a variety of tasks. Students will be asked to interpret data and probabilities to make predictions. Students will be required to understand data sampling and bias in statistical reports, to interpret and construct graphics based on statistical data, and to compare and contrast data sets.
GED questions regarding algebra, patterns, and functions will require students to use variables, equations, algebraic expressions, and algebraic language to perform tasks such as understanding common properties, solving problems, and analyzing graphics. Students should be familiar with linear, quadratic, and exponential equations.
Questions that address measurement and geometry will require students to identify, describe, and analyze the key pieces of diagrams that can aid in solving problems. Students will be asked to apply concepts, principles, formulas, and theorems to solve problems involving area, volume, perimeter, and weight. Questions will require students to be familiar with both metric and standard units of measurement. Students should be able to identify and interpret the slope of lines, y-intercepts, and intersections. Students should be able to identify and plot coordinates on a grid.
