OSAT Middle Level/Intermediate Mathematics (225) study guide
OSAT Middle Level/Intermediate Mathematics (225) · Work through your exam, one topic at a time.
Middle Level/Intermediate Mathematics (225) is a Certification Examinations for Oklahoma Educators (CEOE) test used in Oklahoma's educator certification process for candidates who want to teach mathematics at the middle level or intermediate grades. Candidates have the option to take either the CEOE version or the National Evaluation Series version of this test; both versions assess the same critical content areas, so the choice is about which program path fits your situation rather than about different content. The OSAT Middle Level/Intermediate Mathematics (225) study guide has 4 sections and about 1,178 words.
01Number Sense and Operations
The Number Sense and Operations domain tests flexible work with rational and irrational numbers, integer and fraction arithmetic, order of operations, exponents and roots, scientific notation, ratios, rates, percents, and elementary number theory. Questions often ask for an equivalent form or for reasoning about whether a result is rational.
293 words, about 1 min02Algebra and Functions
Algebra and Functions tests translating verbal relationships into expressions and equations, solving linear equations and inequalities, systems, quadratic relationships, function notation, slope and intercepts, and interpreting graphs. Maintain equivalence: whatever operation is applied to one side of an equation must be applied to the other; multiplying or dividing an inequality by a negative reverses the inequality sign.
294 words, about 1 min03Geometry and Measurement
Geometry and Measurement tests angle relationships, properties of triangles and quadrilaterals, similarity and congruence, the Pythagorean theorem, perimeter, area, surface area, volume, coordinate geometry, and unit conversion. Angles on a line sum to 180°; angles around a point sum to 360°; vertical angles are equal.
296 words, about 1 min04Statistics, Probability, and Data Analysis
Statistics, Probability, and Data Analysis tests summarizing data with mean, median, mode, range, and interquartile range; reading displays; sampling and bias; basic probability; counting; and interpreting association and trends. Mean is the sum divided by the count; median is the middle ordered value, averaging the two middle values for an even count; mode is most frequent.
