Lesson 10 - Reading Scales. The important thing to remember is that you have to figure out what the interval is! Is it going up by 2's, by 5's, by 20's? Try out a few and see what works. The sequences should be pretty easy, but remember, it is going to do the same thing to each number - multiply by 2, add 2, etc.
7th Grade
Spelling - Do the Challenge page today. Remember, tomorrow is Friday, so you will be having a Spelling test over Unit 2! The entire unit is due as well so please make sure you are getting it done.
Grammar - Write a complete rough draft of your "What Makes Me, Me" essay. Don't forget the conclusion and remember, each paragraph should be 4-5 sentences long. The conclusion will have NO NEW information in it. You will be rephrasing and summarizing what you've already written. Read through it and make sure it sounds like you want it to sound. Don't just write and be done!
Literature - Complete the questions for "Rikki, Tikki, Tavi". Thinking About the Selection #1-9 and Analyzing Literature #1-3.
Math - We began discussing the properties of operations today. There is no homework. We will do it in class tomorrow!

Lesson 1-8. Subtracting Rational Numbers. Remember, just because the lesson says "subtract" that you won't always be subtracting the numbers. First, for every problem, you have to determine if you will be adding or subtracting the numbers. If you have a positive minus a positive and the first number is bigger, then it is just a regular subtraction problem. Like 3.57-2.68. For this, you would just subtract like normal and not mess with the signs. However, if you have a positive minus a positive and the first number is SMALLER, you will have to do this:
First, change the minus sign to a plus sign and change the sign of the next number:
3 5/8 + - 5 3/4
Notice that the signs are different, so you have to subtract. Also, notice that the 5 3/4 is bigger, so it needs to be put on top:
5 3/4 = 5 6/8
- 3 5/8 = 3 5/8
Then, subtract. You get 2 1/8, but since the 5 3/4 was negative, the answer is -2 1/8.
Now, if you have a positive number minus a negative number like this:
5.45 - (-3.581)
You would just change the "minus a negative" to "plus a positive" like this:
5.45 + (+3.581)
Now, you have two positive numbers, so you add and keep the same sign:
5.45
+3.581
+ 9.031
Sometimes you will have a negative minus a positive:
-3.58 - 8 3/4
First, you notice that you have a decimal and a fraction. Change the fraction into a decimal like this:
- 3.58 - 8.75
(3/4 = 0.75)
Now, change the minus sign to a plus sign and change the sign of the next number:
-3.58 + -8.75
Now you see that the signs are the SAME, so you add and keep the same sign:
-3.58
+ -8.75
-12.33
Sometimes you will have a negative minus a negative:
-4 2/3 - (-2 4/5)
Remember, "minus a negative" changes to "plus a positive" like this:
- 4 2/3 + (+2 4/5)
Now you can see that the signs are different, so subtract and use the sign of the bigger number. You see that 4 2/3 is bigger than 2 4/5, so it is on top:
4 2/3 = 4 10/15
- 2 4/5 = 2 12/15
You have to make a common denominator and after doing that, you see that the top numerator is smaller, so you have to borrow from the whole number like this:
3 25/15
2 12/15
You took one away from the 4 to make it three, then added 15 to 10 (bottom to top on the top fraction) to get 25/15.
Now you can subtract: 1 13/15
Go back and look at what was the bigger number: - 4 2/3. Since it is negative, your answer is negative: - 1 13/15
I hope this helps!
Please take your time. In mixed problems, change fractions to decimals, then determine if you will be adding or subtracting. If you are subtracting, decide which number needs to be on top. Sometimes you have to switch them!
See you tomorrow!
