As I went though my 4th graders math book, I couldn't find definitions for the rules of Algebra
that was clearly stated and didn't have variables in the examples.
After perusing a few sites I found one that I thought would be good.
Even so, I wasn't to pleased with their examples and removed the
variables from the examples, keeping only a, b, c for simplicity.
Then I just substituted different numbers for each either 1, 2, 3
or 2, 3, 4. I would explain these are simple substitutions
so that the 4th grader would learn variables could be anything.
I've included the Algebra Properties pdf with the information, an education link,
and my source for the definition of the algebra properties. I made a table, then
as you will see I had and issue with it. Finally a summary of
what I've concluded. I would appreciate any thoughts you might have.
Thanks.
