4 More About the LCS Do not be afraid. We expect you to achieve a mastery level of 95% before we will certify you as having mastered Algebra 1. You will not likely achieve this result the first time you attempt to take the course examination. But after review and further practice doing problems you will find your subsequent scores higher and higher until you exceed the proficiency level of 95%. Instructional Philosophy The approach taken by Saxon “math” is what they call “incremental development.” New subject material is introduced in short “chapters” that are called “lessons” in the Saxon book. This approach also puts emphasis on continual review of content learned in earlier years. Thus it should not be surprising to find this Algebra 1 book begins with a review of fractions. Structure of Lecture Notes These notes are built around the Learning Concept Statements (LCS). We make this quite explicit by directly quoting each LCS as we begin its description. The LCS are currently stored in a database and we simply “paste” the relevant row of the data array into the text of these notes to provide the precise LCS text. Mastering Algebra 1 There are well over two-thousand LCS in Algebra 1 but any examination, for practical reasons, will only employ a small subset of questions addressing the subject matter. That subset will be determined by applying a random number generator to each subtopic in this course. Thus if and when you retake the course’s examination, the questions will almost always be different than those encountered before- though they will be covering similar or related “ground.” Click me for video > QuickTimeª and a decompressor are needed to see this picture.
5 Segment 1 The first nine lessons from Saxon’s Algebra 1 comprise Segment One. We chose this length for purposes of demonstrating the capabilities of the Stellar Schools instructional model. It has no mathematical or pedagogical relevance. Lecture 1: Combining Fractions and Combining Line Segments Adding and Subtracting Fractions Saxon Lesson Learning Concept Statement Number Concept Name Description (answers what is this concept?) Question (among many) Correct Answer 1 1 Equalize denominators Cross multiply to force equal denominators What is a common denominator of n/k + m/l? New numerators? kl, nl, mk We begin by reviewing the mechanics of adding and subtracting fractions. Before either of these operations can be completed it is necessary to put all of the terms to be combined to have the same denominators. For any pair of terms we need to find a common denominator. Since multiplying the numerator and denominator of any fraction by the same number does not alter the value of the fraction we can then represent the sum n/k + m/l as ln/lk + km/kl .

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
