Course Syllabus
GED® Math Foundations: Integer & Rational Number Operations Mastery
Course Overview
This 24-session GED® Mathematical Reasoning course develops reliable control of signed integers and rational numbers. Learners move from number-line meaning and equivalent forms to fluent operations with integers, decimals, fractions, and mixed numbers. The final stage applies those skills to money, temperature, elevation, change, estimation, calculator use, and mixed GED®-style problems.
The course emphasizes meaning before memorization. Every operation connects to direction, distance, grouping, or scaling. Each session follows a repeatable cycle: interpret, represent, calculate, explain, check, and correct.
Course Information
- Program: GED®
- Subject: Mathematical Reasoning / Quantitative Problem Solving
- Length: 24 sessions
- Recommended pace: 3 sessions per week for 8 weeks
- Study time: 45-60 minutes per session, plus correction time
- Prerequisites: Whole-number arithmetic and basic fraction/decimal notation
- Recommended mastery target: At least \(80\%\)
- Calculator use: Mental prediction first; calculator verification when helpful
GED® Skill Alignment
Learners compare rational numbers, use absolute value, compute with signed integers/decimals/fractions, distinguish negative bases, evaluate multi-step expressions, translate real contexts, estimate results, and diagnose sign or calculator errors. These skills support GED® algebra, geometry, data analysis, formulas, and word problems.
Learning Routine
- Name the quantity. Decide what each number represents and what zero means.
- Attach the sign. Translate gain, loss, above, below, rise, and fall.
- Choose a representation. Use a number line, fraction model, decimal place value, or expression.
- Predict. Decide the expected sign, scale, and benchmark range.
- Calculate. Apply the rule and show the critical intermediate step.
- Verify. Estimate, reverse the operation, or substitute.
- Correct. Record the error type and a prevention habit.

Assessment and Mastery
Every session ends with a checkpoint, and course-level multiple-choice practice provides cumulative retrieval. Progress when representative work reaches at least \(80\%\), the sign can be explained before calculation, and missed items can be corrected independently.
Classify mistakes as a meaning error, sign error, operation error, fraction/decimal error, order-of-operations error, calculator-entry error, or question-reading error. For each missed item, state the correct relationship and solve one similar problem.
Required Materials
- Notebook or digital notes
- Pencil and scratch paper
- Number-line sketch space
- Fraction/decimal reference sheet if needed
- Scientific calculator or GED® onscreen-calculator practice
- Course lessons and cumulative practice
