Spelling - Unit 21 is due tomorrow. The test will also be tomorrow. If you need to take a makeup test, we will do these tomorrow as well.
Literature - The class took a Selection Test on Tuesday. No homework!
Math - Practice Test. We worked through the first half in class. Here are the rest of the answers - email me if you have any questions!
Seventh Grade
See the last post to watch the videos of the practice test. This will be your only review! I will not go over questions in class unless you didn't understand something from the video.
You can also email me if you have any questions!
Literature - Chapter 22 questions. Be sure you are taking your time answering the questions and write the answers in complete sentences.
Spelling - Unit 22 is due on Friday. No Vocabulary Connections this week!
Research Paper - Since we were not at school today, the outline is due tomorrow!
Eighth Grade
Tuesday's assignment is the handout I gave you. Each has mixed review problems from the last several lessons as well as new problems from Lessons 57 and 58.
For Pre-Algebra, the new concept from Lesson 57 was just Mixed Number Problems where you first have to write an equation to solve.
For example: two and one half of what number is 7 1/3?
Write an equation: 2 1/2 x N = 7 1/3
Then solve by converting 2 1/2 and 7 1/3 to improper fractions. Now you'd have
5/2 x N = 22/3
Now, to get the variable (N) by itself, get rid of 5/2 by multiplying both sides by the reciprocal, 2/5.
22/3 x 2/5 = 44/15
That's it!
For Lesson 58, you are solving distance problems. Remember, every SPEED is a RATE that can be written in rate form.
Here is an example:
Harry could travle 350 miles in 7 hours.
What was his speed?
To find speed, you are finding how many miles in ONE hour? Or miles per hour...that is a rate!
Divide 350 miles by 7 hours to get 50 miles per hour.
How long would it take him to travel 800 miles?
To solve this, first write the two rates implied by 50 miles per hour. Then, choose the correct rate to solve the problem.
At the same speed, how far could he travel in 12 hours? Again, choose the correct rate to solve the problem.
Here are the two questions above worked out:
Algebra I
For the new concepts from Lesson 57, you are adding expressions that have negative exponents in them.
First, change the terms so that there are no negative exponents. Then, find a common denominator to add like you've been doing. These are pretty easy!
For the new concept from Lesson 58, be sure to use the diagrams to help solve the problems. Remember, the 100% box is ALWAYS your OF box. That will help you figure out the answers. I always write the 100% box second - it makes more sense to me - the book shows them written reversed, but it doesn't really change anything.
Here is an example from the book:
Kathy, John, and Susie have only 20 chickens left. If they began with 80 chickens, what percent of the original flock remains?
Since they began with 80 chickens, that is the original flock and accounts for 100% of the flock. Put that in the second box.
In the first box, you will divide it into two sections. Each section is always some % of a number.
Since we don't know the percent, but we know the number, in the top section, we write 20 is wp (what percent). We could write 60 is wp in the bottom section, but we are not concerned about this amount.
Now, you can read from left to write the equation:
20 is wp of 80
Then solve. Remember to write the answer as a percent.
See you tomorrow!Mrs. Swickey
