WEST-E Middle Level Mathematics (NES 203) study plan

WEST-E Middle Level Mathematics (NES 203) · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Mathematical Processes and Number Sense

  • Compute fluently with rational numbers in all four operations, including signed fractions, decimals, and integers, without a calculator

  • Convert between fractions, decimals, and percents and order a mixed set of rational numbers on a number line

  • Apply divisibility rules, prime factorization, GCF, and LCM to solve multi-step number-theory problems

  • Classify numbers within the real number system (natural, whole, integer, rational, irrational) and justify each classification

Your checkpoint

A 25-question self-made number-sense quiz scored at 80% or higher, with every missed item rewritten and re-solved correctly

Week 2

Mathematical Processes and Number Sense & Patterns, Algebra, and Functions

  • Solve ratio, rate, proportion, and percent-application problems (tax, tip, discount, percent change) using at least two methods each

  • Explain and apply the properties of operations and order of operations to simplify multi-step numerical expressions

  • Translate verbal statements into algebraic expressions and equations, including consecutive-integer and age-type setups

  • Identify and correct common procedural errors in worked number-sense solutions

Your checkpoint

A written error-analysis log of 10 worked problems (your own or textbook) identifying the exact step where reasoning failed and the corrected solution

Week 3

Patterns, Algebra, and Functions

  • Simplify polynomial expressions and factor quadratics by GCF, trinomial, and difference-of-squares methods

  • Solve linear equations and inequalities, including compound and absolute-value inequalities, and graph solution sets on a number line

  • Solve systems of two linear equations by graphing, substitution, and elimination, and interpret the solution graphically

  • Apply exponent rules and perform operations with scientific notation

Your checkpoint

A one-page reference sheet of algebra procedures you built yourself, plus 20 practice problems solved with full work shown

Week 4

Patterns, Algebra, and Functions

  • Determine slope, intercepts, and equations of lines from graphs, tables, two points, and word contexts

  • Distinguish linear from nonlinear relationships and identify domain and range from graphs and equations

  • Evaluate and compose functions using function notation, including inverse functions for simple linear cases

  • Model a real-world scenario with a linear or quadratic function and interpret the parameters in context

Your checkpoint

A timed 30-minute, 15-question algebra and functions mini-test scored at 75% or higher

Week 5

Measurement and Geometry

  • Convert within and between metric and customary units using dimensional analysis, including multi-step conversions

  • Compute perimeter, area, surface area, and volume of standard two- and three-dimensional figures, choosing the correct formula

  • Apply the Pythagorean theorem and distance formula to solve geometric and real-world problems

  • Classify figures and angle relationships (parallel lines and transversals, triangle congruence criteria) and justify conclusions

Your checkpoint

A formula sheet with a worked example for each formula, plus 15 mixed measurement problems solved with units carried throughout

Week 6

Measurement and Geometry & Statistics, Probability, and Discrete Mathematics

  • Perform and justify transformations (translation, rotation, reflection, dilation) on the coordinate plane and describe their effects on coordinates

  • Compute and interpret scale factors, similar-figure proportions, and indirect measurement problems

  • Calculate mean, median, mode, range, and interquartile range and choose the appropriate measure for a given data set

  • Read and construct displays (histogram, box plot, scatter plot) and describe shape, center, spread, and association

Your checkpoint

A geometry-and-data portfolio of 12 problems spanning transformations, similarity, and statistics, each with a written justification of the chosen method

Week 7

Statistics, Probability, and Discrete Mathematics

  • Compute theoretical and experimental probabilities for simple, compound, and conditional events, including with and without replacement

  • Apply the fundamental counting principle and permutations and combinations to counting problems

  • Interpret probability models, expected value, and the law of large numbers in context

  • Solve introductory discrete-mathematics problems involving sequences, series, and simple graph or network ideas

Your checkpoint

A 20-question probability and discrete-math quiz scored at 80% or higher, with a written explanation for every answer

Week 8

Mathematical Processes and Number Sense & Patterns, Algebra, and Functions & Measurement and Geometry & Statistics, Probability, and Discrete Mathematics

  • Integrate all four domains by solving mixed-topic problems under timed conditions without reference materials

  • Diagnose remaining weak areas from practice-test error patterns and target the top three with focused review

  • Practice explaining solution strategies in writing, as required by the mathematical-processes strand

  • Build and rehearse a personal test-day pacing and strategy plan

Your checkpoint
