Re: [MathWithoutBorders] Algebra I - Do we need to finish entire text?
- I am of two minds on this. 1). I had my dd double up in math for 1 semester. She did the end of Foerester's Algebra 1 and started Geometry that same semester. 2). I have heard that a few chapters could either be skipped or condensed as Foerester's Algebra 1 covers a lot of material, some of which is closer to Algebra 2 material. (But I do not remember which chapters specifically.)I intend to have my son (14) continue with Foerster's Algebra 1 over a year and a half and again double-up with Geometry for one semester.Michele
- The two answers are equivalent. You can move the terms around on one side of an equation as long as you move the sign with the number (or expression) it is part of. This is the commutative property of addition.
