The Complete Math Roadmap for Earning Your GED at 16
Let’s start by saying this: It’s never too late to learn math. If you’re 16 and want to earn your GED but feel stuck because math seems overwhelming, this guide is for you. We’ll break down exactly what you need to know, step by step, to build the skills required to pass the GED math test. No jargon, no pressure—just clear explanations and practical advice.
Start With the Basics: Arithmetic
Since your formal education stopped around 5th grade, let’s begin with foundational arithmetic. These skills form the backbone of almost every GED math problem.
1. Whole Numbers and Operations
– Addition/Subtraction: Practice solving problems like $48 + 27 or 135 – 89. Focus on carrying over and borrowing numbers.
– Multiplication/Division: Understand times tables up to 12×12. Learn how to divide multi-digit numbers (e.g., 144 ÷ 12).
2. Fractions and Decimals
– Simplifying Fractions: Reduce fractions like 12/16 to 3/4.
– Adding/Subtracting Fractions: Start with common denominators (e.g., 1/4 + 2/4), then move to unlike denominators (e.g., 1/3 + 1/6).
– Decimals: Convert fractions to decimals (e.g., 1/2 = 0.5) and practice adding/subtracting money amounts (e.g., $3.25 – $1.75).
3. Percentages
– Basics: Learn that 25% = 0.25 and 75% = 3/4.
– Real-Life Applications: Calculate discounts (e.g., 20% off a $50 item) or tips (e.g., 15% of a $30 meal).
Level Up: Pre-Algebra and Geometry
Once you’re comfortable with arithmetic, these topics will help you tackle more complex GED questions.
4. Basic Algebra
– Variables: Solve equations like x + 5 = 12 (answer: x = 7).
– Simplifying Expressions: Combine like terms (e.g., 3x + 2x = 5x).
– Word Problems: Translate sentences into equations. For example, “Twice a number plus 10 equals 30” becomes 2x + 10 = 30.
5. Geometry Essentials
– Shapes and Formulas: Memorize area formulas for rectangles (length × width), triangles (½ × base × height), and circles (π × radius²).
– Angles: Understand complementary (sum to 90°) and supplementary (sum to 180°) angles.
– Coordinate Plane: Plot points like (3, -2) and identify quadrants.
Critical Thinking: Data and Probability
The GED math test includes questions that require analyzing information.
6. Graphs and Charts
– Interpret Bar/Line Graphs: Identify trends (e.g., Which month had the highest sales?).
– Pie Charts: Calculate percentages (e.g., If a chart shows 30% for “transportation,” how much is that in dollars for a $1,000 budget?).
7. Probability Basics
– Simple Probability: Calculate the chance of an event (e.g., Probability of rolling a 3 on a die = 1/6).
– Combined Events: Use the word “and” for multiplying probabilities (e.g., Probability of flipping two heads in a row = ½ × ½ = ¼).
Practical Tips for Learning Efficiently
Use Free Resources
– Khan Academy: Their free math courses align with GED topics. Start with “Arithmetic” and work your way up.
– YouTube Channels: Search for “GED math prep” for bite-sized lessons.
Practice Daily
Even 20–30 minutes a day helps. Focus on one skill at a time—master fractions before moving to decimals, for example.
Take Practice Tests
The official GED website offers sample questions. Track your progress to identify weak spots.
Ask for Help
Join online forums (like Reddit’s r/GED) or local study groups. Don’t let confusion pile up—ask questions early.
Final Words of Encouragement
You don’t need to rush. Many people earn their GED after years away from school. Celebrate small wins: Solving a tricky equation or understanding a geometry concept is progress. Math is a skill, not a talent—it gets easier with practice.
Remember, the GED math test isn’t about perfection. It’s about showing you can apply basic concepts to real-world problems. With consistency and the right resources, you’ve got this!
