NGSA Mathematics study guide
NGSA Mathematics · Work through your exam, one topic at a time.
NGSA Mathematics - often written out as the Next Generation Science Assessment Mathematics test - is a standards-based mathematics assessment used to gauge whether a student has the quantitative reasoning and problem-solving skills expected at the end of a given grade band. It is aimed at students preparing to move into more advanced coursework, at teachers and curriculum leads who need an external check on instruction, and at families who want an independent read on readiness. The NGSA Mathematics study guide has 5 sections and about 2,048 words.
01Number and Operations
This domain tests whether you can move confidently among whole numbers, fractions, decimals, and percentages, and whether you can choose the correct operation in a short word problem. Expect place value, rounding, factors and multiples, equivalent fractions, ordering numbers, and the four operations with regrouping.
443 words, about 2 min02Algebra and Functions
This domain tests pattern rules, missing numbers, simple expressions, one-step and two-step equations, and input–output relationships. You need to translate a written rule into symbols, substitute values, and use inverse operations to solve for an unknown.
404 words, about 2 min03Geometry and Measurement
This domain tests properties of 2-D and 3-D shapes, angle relationships, perimeter, area, volume, and conversion of units. You should know formulas and when each one applies, and be able to read a diagram’s labels without assuming lengths that are not marked.
411 words, about 2 min04Data Analysis, Statistics, and Probability
This domain tests reading tables, pictographs, bar graphs, and line graphs; calculating mean, median, mode, and range; and assigning simple probabilities. You need to interpret scales, compare data sets, and describe outcomes using fractions, decimals, or percentages between 0 and 1.
393 words, about 2 min05Mathematical Reasoning and Problem Solving
This domain tests multi-step word problems, estimation, pattern and logic puzzles, and the ability to explain why an answer is reasonable. The mathematics may come from number, geometry, or data, but the mark depends on selecting the right operations, keeping track of units, and answering the question actually asked.
