In this lesson, our professor Vincent Selhorst-Jones gives an introduction on math concept petting zoo. He discusses how the zoo works, what you should do, and the following topics: intersection and union, sequences and patterns, even and odd properties, primes, percent, percent change, average, absolute value, solving equations for unusual things, distance, radicals, exponents, concepts of a function, domain and range, function transformations, expanding factors, factoring and solving polynomials.
If you want to do well on the Math section of the SAT, you need to be familiar with a wide variety of concepts. This is the first of two lessons covering the vast majority of the concepts on the SAT.
In the first lesson, we'll generally cover topics relating to the interaction of numbers, equations, and functions. The second lesson will focus more on geometry, shapes, and a few miscellaneous topics.
In the Zoo, each concept will be presented by showing a question based on the concept. While there will be some explanation of the questions, the point of the Zoo is to quickly review concepts, not teach them.
As you watch this lesson, make sure you have a pencil and paper. Make sure you could solve each problem on your own before the answer is revealed. If you're not absolutely certain you could, pause the video and try to work it out yourself before you continue watching.
Whenever you find a concept you don't know well, write it down and note how much help you need.
Later, after you've finished watching the lesson, go study the concepts you wrote down. Begin with the ones you find most difficult. Watch the corresponding SAT Math-specific lessons, and if you still need more help, browse Educator.com, search the web, or talk to someone who is good at math.
Here's a list of all the concepts in this half of the Zoo:
Intersection and Union,
Sequences / Patterns,
Average: Mean, Median, Mode,
Solving Equations for Unusual Things,
Distance = Speed · Time,
Concept of a Function,
Domain and Range,
Expanding Factors (aka: FOIL),

Educator.com recommends The Official SAT Study Guide published by The College Board, the administrators of the actual SAT test. In it, you will find additional practice questions and a review of all subjects, along with 10 official SAT practice tests. Our instructors work through several of the practice tests in real time, going through their thought processes and test-taking tips.
