Great minds think alike.
Ken left this comment, about the negative exponent problems Christopher was trying (and failing) to do,
Er, isn't this algebra and not "pre-algebra"?
I suppose pre-algebra now is pick an algebra lesson (and I use that term loosely) at random, teach it poorly or not at all, and ask the student to memorize the answer solve the problem.
Saturday night, after Ed had lived through his first Screaming Pre-teen session, he said, "This is spiralling."
What he meant was, pre-algebra is not pre-algebra.
Pre-algebra is algebra.
Pre-algebra is called pre-algebra, we both think, because it's the beginning of the Second Spiral in an American child's life: the Algebra Spiral.
In K-6 or K-7, kids experience the Arithmetic Spiral.
Then, starting somewhere in middle school, they move on to the Algebra Spiral.
They spend two years learning Algebra 1:
Both courses are algebra.
This is the only explanation we can come up with for the torture that is Phase 4 math. (OK, there's the This was supposed to be a course for gifted children, but then high achievers jumped on board and ruined everything meme, which could be true. That's a side issue I'm curious about: are the one or two gifted kids learning well in this course? I'd love to know.)
Leaving gifted children aside, Prentice Hall Mathematics: Explorations and Mathematics was not written for gifted children. As I understand it, it's intended for use in the regular 8th grade pre-algebra course. (Of course, if that's true, then the good news is: WE'VE BEEN TEACHING ALGEBRA TO 8TH GRADERS FOR QUITE SOME TIME NOW.)
Christopher is trying to learn one whole brand-new topic in algebra a day, every day.
He can't do it. Period. I'm assuming the gifted kids can, but I'd bet the ranch they're the only ones.
What we're doing now is the equivalent of forcing an 11-year old to cram for tests every single day of his school week. We're ramming rules, numbers, notations & mathematical conventions into his head so he can — yes — regurgitate them on a test, knowing all the while that he'll forget everything we're 'teaching' as soon as the test is over.
Why would a textbook present this much new material in one year's time?
J.D. will have an answer, I'm sure. Perhaps this book is intended to be used over two years' time?
However, I have the Teacher's Edition, and I don't get the sense that's the case.
I think the book is set up to 'cover' a vast amount of basic algebra in 1 year.
Glencoe's Table of Contents
The Glencoe pre-algebra text, which I believe is the other 'big,' widely used pre-algebra book, has a terrific Parent abd Student Guide available online.
The book has 14 chapters:
Chapter 1 - Tools for Algebra and Geometry
Chapter 2 - Exploring Integers
Chapter 3 - Solving One-Step Equations and Inequalities
Chapter 4 - Exploring Factors and Fractions
Chapter 5 - Rationals: Patterns in Addition and Subtraction
Chapter 6 - Rationals: Patterns in Multiplication and Division
Chapter 7 - Solving Equations and Inequalities
Chapter 8 - Functions and Graphing
Chapter 9 - Ratio, Proportion, and Percent
Chapter 10 - More Statistics and Probability
Chapter 11 - Applying Algebra to Geometry
Chapter 12 - Measuring Area and Volume
Chapter 13 - Applying Algebra to Right Triangles
Chapter 14 - Polynomials
That's a lot.
Each chapter has 8 to 10 separate lessons, all of which cover new material.
Approximately 130 separate items of brand-new material for students to learn in a 180-day school year?
This weekend I pulled out all of the individual topics, so I could try to keep track of them — so I could try to figure out quickly what Christopher needs to practice today.
Here's the list.
