Week 1: Pre-Algebra: Math Equations and Inequities

Greetings,
Welcome to the first Math Lesson.  The format will include a short video that will review math topics, then there will be questions to answer.  Many of the questions will be autograded when you submit at the end of a lesson.  I will grade the other questions at least twice per week, so you will know your score in a day or two after you submit.  Also, I may add a comment to your answer in Formative.  You can also ask me questions through the comment feature in Formative or email me directly at rshaw@fergflor.org.

As lessons are released, they will stay open for about five weeks, so if you miss a week because of a trip, you can catch up.  You can also redo any questions or lessons as many times as you wish.

Let's get started with Expressions, Equations, and Inequalities.

Sincerely,
Dr. Shaw

An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value. a ≠ b says that a is not equal to b. a < b says that a is less than b. a > b says that a is greater than b.
