Yesterday we learned how to evaluate expressions when given the value of a variable.
For example:
t + 3 x 5 =
They gave us that t = 4
4 + 3 x 5 =
4 + 15 =
19
We would still have to solve the multiplication first due to the order of operations (PEMDAS)
In social studies we reviewed the difference between the Roman Empire and the Roman Republic. We learned the the Empire was ruled by one ruler whereas the Republic was ruled by a few. We also learned about the Hellenistic Age is which the Greek culture was spread through a vast land. It was spread to any place that was conquered. Keep reading 291-306 and you will do well on the midterm.

Yesterday when I got to school I was unable to give the DA math test. I did not have the correct copies. I improvised and we moved on with our studies in math and social studies. That being said, the social studies midterm will now be on Thursday instead of Friday.
In math yesterday, we reviewed the order of operations: PEMDAS (parenthesis, exponents, multiplication/division (left to right), and addition/subtraction (left to right) We did a long example on the board that was more in depth than the ones that they were required to do for homework. I showed them how I wanted them to show their work and that they needed to show each individual step of the process. For example:
8 x 5 + (6^2 - 8 (1 x 1)) -4 =
8 x 5 + (6^2 - 8 x 1) - 4 =
8 x 5 + (36 - 8 x 1) - 4 =
8 x 5 + ( 36 - 8) - 4 =
8 x 5 + 28 - 4 =
40 + 28 - 4 =
68 - 4 =
64
If they do it in this manner it will prevent them from making silly mistakes.
In math today and tomorrow, we will be working on evaluating an expression when given the value of the variable and writing an expression based on word problems. For example:
X + 4 when X = 6; I would plug 6 in for X and solve: 6 + 4 = 10 So 10 would be my answer.
The other would be something like: Johnny went to the store and bought some apples. Then he bought 6 oranges. If he bought 15 pieces of fruit, how many apples did Johnny buy?
They would have to come up with the expression X + 6 = 15
In social studies yesterday, we reviewed what Rome and Greece contributed to our system of government. We learned that Athens was the birthplace of democracy. We also learned that Rome had a democracy that was a little bit different. It also included separation of powers, which meant they had more than one branch of government. We know that the forum was the most important place in Rome. It was where they had money changers, who exchanged currency, banks, sporting events, trials, basically anything that was important was done at the forum. We also read about the Peloponnesian war, which was started because Sparta and other city-states in the Peloponnese were afraid that Athens was gaining too much power. It ended when Athens was defeated.
We will continue to review some important concepts today as well.

I hope everyone had a great Thanksgiving holiday. We are going to keep trucking through our standards in both math and social studies. We have 3 more full weeks of school before the semester is over.
This week, we are going to be reviewing for our social studies midterm. If you would like to help your child review at home, they need to read and understand all of the important concepts of Ancient Rome and Ancient Greece on pages 291-306. We will be reviewing them in class as well. The social studies midterm will be given on Friday 12/2.
In math, we are moving into a new concept. Today I am giving them a test to see where they are in math so far this year. Starting tomorrow, we will be beginning to work with numerical expressions and how the different properties, such as the distributive, commutative, and associative properties work. This will be our introduction into our algebra unit where we will be solving equations to find the value of a variable. Also, we will be graphing equations as well.
We will be taking the chapter 6 test on these concepts on Thursday, December 8. Before the three weeks is over, we will be reviewing previously taught concepts and be taking our district math assessment as well. I will keep you posted as the weeks go on.

Yesterday and again today we are having a math competition in class. We also are working on our essays for our DBQ. They are due today before the kids leave the classroom. I hope everyone has a great Thanksgiving break and is ready to start algebra when we return!!!

Today we will be taking our big test on decimals, fractions, and percents. I think that the kids are going to do a great job on this test. Most of them did very well on the review questions on Tuesday. We also are going to be beginning our persuasive essays on our DBQ question. I will be collecting the DBQs today so that I can upload the grades onto Edline.
The debates yesterday went okay. Some classes did a better job than other classes, but it was definitely a learning experience for all of us.
Have a great weekend!

Yesterday wasn't so bad. I think the kids got it. Some even came up with their own ways to solve them.
Today in class we are going to be actually doing our debate. We are also going to be calculating the actual percent of a number. It is going to be a good day. I can feel it already.

Sorry it has been so long since I have been on. Wedding plans and my son being sick has been very hectic.
This week, we are finishing up our unit on fractions, decimals, and percents. We will be having an end of unit test on Friday. The kids got a chance on Tuesday with the sub to do a few pages of review. If they didn't have problems with any of the sections, then they will do fine on the test.
We still have two new concepts to learn today and tomorrow. We are going to begin with estimating percents today. This topic is a little tricky, but I will explain. If the question is asking ABOUT how much is 78% of 309, the kids would round that to 80% of 300. There are a couple of ways that they can then calculate this. They can multiply .8 * 300 and they would get 240, or they could look at 300 and think, what is 10% of 300. They would get 30, then multiply it by 8 to get 240. They also could set it up like a ratio and do 80/100 = x/300. They know that they have to multiply 100 * 3 to get to 300, so they would do the same to the top and do 80 * 3 and get 240.
Tomorrow, we will be learning how to find the exact percent. This will be a review on how to multiply decimals. I try to remind them that when they see the word of in a word problem, it means to multiply. So if the question asks for 76% of 352, they would multiply 352 times .76 and get 267.52. This is how you would find an exact answer.
We are going to be beginning our debate in social studies today. The kids are going to meet with their teams and formulate how they are going to go about defending their choices so that they are well prepared for tomorrow's debate. On Friday in social studies when they finish their math test, they can begin working on their culminating essay for the DBQ. It is a persuasive essay on Rome or Athens, which had the better system.
Since I was out on Tuesday, I am going to give them time next week to work on their essays as well. If they want to work on it over the weekend they can.
I hope this gets us all caught up.
