**Course Description: **Students will work through basic operations with integers, fractions and decimals. Students will progress through the study of number properties as well proportions, rates, exponents and radicals.

DIRECTIONS: This is an ordered list of 139 videos and exercises (with links) to complete Khan Academy arithmetic and pre-algebra. (This is the same course that it was *before* Khan Academy aligned with Common Core. I was able to update Khan Academy’s links without changing the teaching. Where they have eliminated exercises, I just found alternatives on other sites.) You will start at the top of the page with Addition and Subtraction and work your way down in order. Make sure you read the directions *every* time. The first link on each line is to the video unless marked differently. You can move onto the exercise as soon as you know the material. That means you can do the exercise without watching the video if you already know how to do it. At some point, you should probably be watching all of the videos. When you do, write the problems down and work through them with the teacher to help you stay focused and to make sure you can do it too. Some days you will be doing more than one exercise. Some days you won’t make it through one whole exercise. You will stay on an exercise until you are proficient. (According to Khan Academy that’s the first one correct or five correct in a row. I suggest getting the first one wrong on purpose!) You should be able to do five in a row correct before you move on. One suggestion is to set aside 20 – 30 minutes for math each day. When you stop in the middle of an exercise, it should remember how many problems you’ve done.

Make sure you make an account at Khan Academy and log in! (If you plan to use Khan Academy’s built in tracking, please understand that Easy Peasy is not following entire courses built by Khan Academy; therefore, it may not show “mastery” in the records. It is suggested that you print this list of videos/exercises to check off progress by checking of videos and exercises completed.)

- If it is even, then you can divide it by 2.
- If it ends in 5 or 0, then you can divide it by 5.
- If you can add up the digits and divide the sum by 3 or 9, then you can divide the whole number by 3 or 9. Example 69: 6 + 9 = 15 You can divide 15 by 3 so you can divide 69 by 3.
