Eighth Grade Math - First Semester
This file contains 5 emergency and 84 regular lessons based on "Passport to Algebra and Geometry" by Larson, Boswell, Kanold & Stiff copywright 1999 by McDougal Littell.
These were actual lessons quizzes handouts and midterm taught in the 2004-2005 school year. The book is quite good and two of the students won scholarships to private schools. One girl scoring the highest on the State Test ever achieved by that school.
If you're homeschooling, the book is easy to get. I got it online for 99

A short introduction to Limits
Limits mark the transition from Algebra to the Calculus. This suite can be used as an end of year unit or as a beginning of year unit for Precalculus or Calculus, respectively.
This unit is "short" because it doesn't belabor the lefthand and righthand limit concept and it doesn't present any theorems - just straight concepts with figures and calculations.
Limits are defined, indeterminate forms are examined, slope, tangent and derivative are discussed while antiderivative and definite in

A Brief Encounter with Vectors
This is a brief encounter with vectors: After the nine lessons the student should be able to translate the skills gained herein to other disciplines. Four lessons including review and quiz for both plane and space vectors with a bridge discussion (see the preview) of similarities and differences between 2 and 3 dimensions summarize the unit.

A Rotation of Axes
At the high end of applied Trigonometry in Analytic Algebra or Precalculus courses we encounter the Rotation of Axes, always with conics. There is a practical use for this technology because it teaches us to interrelate quantities in different frames of reference.
The actual rotation requires significant calculations and the theory is developed by the trigonometric difference and multiple angle formulae. It's always a chore to do one of these rotations - but your students should be aware tha

Solving Triangles
We solve triangles using the three laws: Cosines, Sines and Tangents - in addition we show derivations of the three laws and, in the case of the law of tangents, Newton's Formula.
As our presentation is rather parsimonius, we offer talking points in the vocabulary section.
We suggest the use of the Law of Tangents for both SAS and SSS solutions. And,demonstrate the traditional use of the laws of Sines and Cosines as well.
The unit is completed with a discussion of SSA and the ambiguous case.

A Geometric Derivation of the Trigonometric angle sum formulas
This is a pictorial derivation of the sine and cosine of the sum of two angles. It has helped us to understand the outcome by actually seeing the quantities in play. And, for our visual students, the concept is solidified.
We suggest that you use this as a handout to accompany your presentation in class.
The verbiage is parsimonius - but we offer some talking points in the Vocabulary section.

My own education history
I’m from Boston. I was educated at Boston Latin School (Boys Latin) and then at Boston Technical High School (for the Junior and Senior years). I attended Northeastern University, and participated in their “co-operative†program first as an Electrical Engineering major (2 yrs) and then as a Math major (when I transferred to the College of Liberal Arts, I had my choice of Physics, Mathematics or Chemistry for my major field of study). I chose Mathematics.
After receiving my Masters degree from Boston State College, I was eligible to be certified in Math, Physics and Chemistry. I have (had) a life certificate from Massachusetts in those three subjects since 1979.
Additional biographical information
Mr. White is originally from Boston. He was accepted to and attended Boston Latin School, the requisite admission test was waived for Orrin. With family roots in Downeast Maine, it is no surprise to find that he spent every Summer there. His family called Orrin “Whizzer†but his friends called him “Wizardâ€. He was popular with the “natives†and learned many things from them. Those people have a history of self-sufficiency. Among other things, they taught him how to Dig Clams and Fish for Lobster.
In college Orrin first trained in Electrical Engineering – he can wire just about anything you need to have wired. You see – Northeastern wasn’t just a book learning school – they sent out their students to work in the real world. The Northeastern Co-op Graduate has practical experience as well as the Theoretical knowledge. You can apply the adage “they hit the ground running†to these Graduates.
His book "Spreadsheet Sorcery" is as yet unpublished.
