Formulas & Vocabulary Section1. Expression:

A mathematical sentence which does not contain an equal sign. 3x + 8 + 4x –y is an expression. In an expression, you do not solve for any variables. Expressions are simplified by combining like terms

2. Equation:Equations are sentences which do have an equal sign. 3(x + 8) + 4x = 32 is an equation. With equations, you do solve for any variables. When you see an =, you are to find the value of the variable.

Questions are located in the Knowledge Map area:

Using the Khan Academy8. In the Knowledge Map area, you can type the name of the assigned topic here,.

or you can click on the main topic here

Using the Khan Academy9. If you double click on Decimals, all the subtopics under decimals appear.

I’m going to select ‘Adding Decimals’, and we’ll look at the questions and grading next.

Mastering the TopicsThe Khan Academy topics are not considered tests because you can do as many problems as it takes to get 100%. The goal is to master the topic, not just take a test, get 60% and move on. This is all it takes to get 100%, as long as it is

completed before the deadline.

Mastering the Topics

At this point, I’ve done 5 questions and missed one. If you cannot get 5 in a row correct, you will still receive 3 points for each correct answer. If you stop now, with 4/5 correct, what is your percent score for this topic?

Since you have not answered 5 consecutive questions correctly, your score, if you stop now is 4*3 or 12%.

Mastering the Topics

How you are graded:

Achieving Mastery & Grading

7. There are some topics that require only 8 consecutive

correct answers to master. Others require 10. You can do as

many questions as you need to until you have the required

8 or 10 correct in a row. I will provide you a list of the mastery topics and their due dates for the first

quarter. Your homework grade is based on practicing the problems

and achieving mastery by the due date each week.

Practice Area ExamplesA. Each correct answer results in a set of leaves moving up into the stack.

B. Once a group of questions has been completed, you are shown a summary. If you look at the leaves you can see 2problems were missed. Mastery has not been

achieved.

Practice Area GradingA. Mastery before due date: 100%B. Mastery within 3 days after the due date: 75%C. Because you should be rewarded for your efforts, you will receive 2 points for each question answered, correct or not, up to a

maximum of 70%. If you answer 100 questions but still cannot get 10 consecutive

correct, you will still receive a grade of 70.D. Looking again at the last example, if you stopped at this point,

your score would be 16%--8 questions @ 2 points each. Mastery is achieved through repetition. If you keep working the exercises, there is no doubt you can master every topic.

Please do not wait until Saturday to begin the week's

exercises. If you start early in the week, you can bring

any questions you may have to class and receive help.

Check the v6math.blogspot.com site for the weekly topics, links to help you achieve mastery, and other resources.

Good Luck. The sooner you make this part of your regular routine, the more success you will have.
