Pre-Algebra

What is Pre-Algebra?

Pre-Algebra is the study of everything after long division, up until you get just before polynomials in algebra. So it actually should include some algebra basics.

According to some math advisors whom we have consulted with - teachers and professors who have become frustrated with the "new math" or the Common Core math that is being pushed on school kids - there is an orderly, logical progression in learning mathematical skills. No matter how "relative" the new math publishers try to make things with funny videos or word problems using faddish lingo, you can't force the skills to be mastered. Some children might be able to "get through" a lesson or exam, they may even be able to score well on an assignment or exam, but retention is very difficult if concepts are taught out of order. The human brain processes information in specific ways, and again, math concepts need to be in the logical order that the brain will process the information - which will then produce the most retention.  Retention is critical for advancing to higher math without frustration.

Go for mastery, versus a passing grade!  It is critical when you are teaching math that you do not move forward until your child has mastered the concept.  If your child gets a "B" in math, it doesn't mean they understand what they are doing.  And if that B is because they missed a critical step, then they will likely struggle in their math career.  Getting a "B" essentially is a signal that your child does not understand about 15 to 20 percent of the concepts.  

Also remember that if your child does not do well in 6th grade math, it does not mean they are behind.  Go back to these lists, and start from the beginning, and think of the progression as mastery, versus grade levels.​  Once they have mastered all three sections (A, B, and C) of the Pre-Algebra concepts below, they are ready for Algebra, which is 9th grade.  So don't let grade levels intimidate you or tell you what your child cannot do.


BEFORE PRE-ALGEBRA

Here is the logical progression which must be mastered before pre-algebra:

  • Counting and Sorting
  • Addition
  • Subtraction
  • Multiplication
  • Division

From our director:

"When I taught remedial math to homeschoolers (kids who had been moved to Algebra who were struggling)...nearly 100% of them had to back all the way up to long division or right after long division when they were introduced to fractions.  That is where they were rushed through..."​


Keep in mind, that word problems or discussion questions involving math are absolutely essential to have that retention. From one of our members: "When I was in school, my instructors never made me do the word problems because I did so well on the drills (you know, 50 or 60 number problems in a chapter??) This caused a hindrance for me when I got into high school and was preparing to take the pre-college exams. I simply went blank on the word problems and I did not do well.  I hated math. Hated it. Because I could not reason with it."

Drills, drills, and more drills will only teach your children to expect more drills. It doesn't mean they are liking what they are learning, which in our opinion interprets to - it doesn't mean they will retain. Discussion and application will strengthen retention. Now, the ACT and SAT exam (and most state exams) are primarily word problems. As of this date, those exams are still very relevant for kids wanting to get into college and to do well. So never skip the word problems! As a matter of fact, our experts suggest that you have the child do the word problems first, then the drills if they are needed. They should be doing way more word problems (sometimes called story problems) than worksheet drills.

As students work through division, be sure they fully understand long division BEFORE you introduce fractions. Fractions are essentially division problems, they just use a different order and different symbols than regular division or long division. There are some people who say you can teach a toddler fractions. Yes, you can to a degree. However, they don't understand fractions as a division problem because they haven't learned multiplication yet. Therefore later on, our experts say that they could have difficulty with more complicated fractions. So again, master long division before fractions.

Once your child has mastered long division, you are ready for pre-algebra (not just a passing grade, but they have mastered it), the logical order of pre-algebra is as follows, and can be divided into three sections.  Some kids can do all of this in less than a year, for some it takes 2-3 years.

Pre-Algebra Part A

Master everything in this list - in order - before you go to list B.  

NEW!  List A and List B now have videos and worksheets as supplements for PLUS GOLD and Plus Legacy members to teach the concepts on this page - it has been extremely helpful for mastering pre-algebra as well as reviewing important concepts for students who are further along in algebra but are stuck.  See below for the link to access the Pre-Algebra Mastery videos and worksheets!

Pre-Algebra Part C

A final area of what we consider pre-algebra is the ability to see patterns and to turn the concepts into graphs. Do it in this order as follows:

Note:  This final section can be skipped if you are going to have your child do high school Algebra, because it's included in those texts to slow kids down in high school.  The following list is considered "Algebra" in high school.  However, if you are going to go from Pre-Algebra to college level Algebra, then you must master Section C.  We teach more about dual credit college courses in our Homeschooling High School and Beyond Course for Plus members.

Once the child has mastered all of the above, then and only then are they ready to proceed to algebra. According to our experts, if your child has not mastered all of the above, then they will struggle in algebra and higher math. These concepts will also make geometry so much easier!
