How to Use This Course

Pre-Algebra, as presented by Charlene Johnson on, is a full 40-week course. Each unit builds on previous lessons and so should be studied sequentially by the student to completely understand the topics. The course is structured so that the student can easily find the topics they may want to review while they are working through this class. The student will learn facts about a topic, how to expand on those facts and associate them with previously learned facts, how to apply these facts to real life, and review before moving on to the next topic. Each unit includes printable instructions, worksheets, and answer keys. As presented, if all units are completed, this course is equivalent to one year (two semesters) of a typical 8th grade (or earlier) Pre-Algebra course. Please check your state’s academic requirements if information is required on a transcript.

Course Details

Course Introduction

This course is made up of ten month-long units which are each divided into four weekly lessons. Each month the topics will build on previous topics in a logical fashion so that, over the course of the next year, you can progress through a Pre-Algebra curriculum. The modules will also be designed so that you can pick and choose modules for review or extra emphasis on particular topics. The modules include topics such as Basics Review, Decimals, Fractions, Percents, Integers, Exponents, and Equations.

Each module will use the following format:

  • Week 1—Just the Facts
  • Week 2—Now What?
  • Week 3—Let’s Apply
  • Week 4—What Did You Learn?

Week 1 will be designed to teach the facts about the new topic. Week 2 will help you expand on these facts and associate them with previously learned facts to gain an integrated approach to Algebra. Week 3 will help you learn to apply these new facts to real-world situations, and Week 4 will review to ensure you’ve gained a good understanding of the topic so that you can move on to the next.

Each lesson within the module will include a small section of instruction and a number of problems to work to practice this new skill. Occasionally I will include a “Fun with Math” lesson that won’t necessarily be linked with the current topic, but will just be a fun math fact.
