SIXTH GRADE

Today's assignment is the handout about outliers and their effect on the mean. An outlier is a number in a data set that is much smaller or much larger than the other numbers. In other words, it's the number that doesn't belong with the rest. It's different. For example, given the following data set:

25, 28, 24, 8, 23, 27

8 is the outlier because it is the number that is different from the others. Sometimes the outlier can be larger.

I can find the mean of the 6 numbers above (including the outlier) by adding and dividing by 6. The sum of the numbers is 135 and divided by 6 is 22.5, so with the outlier, the mean is 22.5.

If I took the outlier out, then the sum of the other 5 numbers would be 127. If I divide 127 by 5 (not 6, since I took a number out), I get 25.4

You can see, including the outlier, the mean is smaller. So a small outlier will bring the mean down. The same works for an outlier that is much larger. It will raise the mean.

Today's homework is to find the median and mode. You are doing page 68, #6-16. Remember to use your notes in the yellow and blue foldable thing in your Brownies.

SEVENTH GRADE

No class because of trip to Mount St. Mary's.

SEVENTH GRADE PRE-ALGEBRA

No class today, but there is a test tomorrow! Here is a video with the rest of your test review.

EIGHTH GRADE PRE-ALGEBRA

You are doing evens only on the worksheet - working the same type of problems as yesterday. You can skip #34.

ALGEBRA I

We spent class time doing Slope notes. No homework!

See you tomorrow,

SIXTH GRADE

We spent today discussing misleading graphs. The homework is to redo a graph from the SmartBoard correctly. Most finished in class.

SEVENTH GRADE MATH

The homework for today is more adding mixed numbers. You do NOT have to do the whole page. There are a lot, so you will have class time to work on it tomorrow.

SEVENTH GRADE PRE-ALGEBRA

The class used today's time to work on corrections. No homework!

EIGHTH GRADE PRE-ALGEBRA

The homework for today is the assignment with matching an inequality to the correct graph and solving 4 two step equations.

ALGEBRA I

No homework! We timed the cars today to find the speed. Tomorrow we will run the activity, solving distance problems and then running the cars to verify the answers. It'll be fun!

See you tomorrow,

Mrs. Swickey

SIXTH GRADE

We began reviewing for the graphing test today. The test will be on Wednesday and Thursday. It is a two part test because of how many graphs have to be created. That takes awhile! Tonight, be sure to do graphs 3 and 4 from the review.

SEVENTH GRADE MATH

Today's homework is multiplying mixed numbers. You are doing page 138, #19-31. Remember to first change mixed numbers into improper fractions by doing the U-turn. Then cancel where you can and multiply across. If your answer is an improper fraction, change it back into a mixed number. Also, for the first 4, the word "of" means times. So you are multiplying. Be sure to put the whole number over 1.

SEVENTH GRADE PRE-ALGEBRA

More practice with equations with terms on both sides. You are only doing #1-18 on the worksheet.

EIGHTH GRADE PRE-ALGEBRA

You are working on addition and subtraction inequalities. The homework is Lesson 6-5 in the textbook. I don't have the page number handy. You are starting at 1 and ending at the end of the section on solving and graphing on a number line.

 

ALGEBRA I

Homework for tonight is the Distance Word Problems where you have to decide if it is an equal distance problem or a total distance problem. Let me know if you need help!

See you tomorrow,
