Long time no post

I realize I haven't posted any practice problems in a while or a week in review. I apologize for that. The practice problems were not getting turned in for the most part so I am in the process of coming up with a different system.


Grades are due on Thursday so please come to tutorials if you need extra help.


Have a great day!

10/1/10 Week in Review

We have made it through 6 weeks of school! Progress reports come out on Wednesday. Remember I have tutorials every Tues/Thurs from 4:15 to 5:00. Please come by, especially if you are having trouble in class.

This week we learned how to do different operations with fractions. Particularly how to add, subtract and divide. We know that when we add or subtract we MUST find a COMMON DENOMINATOR!!!! The common denominator must be a multiple of both denominators. However, when we multiply or divide fractions we do not have to find a common denominator. To divide fractions we actually multiply by the inverse. So to say it more simply, flip and multiply. We only flip the second fraction though. Another important thing to remember is that if you have a mixed number (4 1/5) you should change it to an improper fraction before you do anything with it.

This coming week we will be polishing these skills and practicing them daily. Please see me if you need extra practice. I have a workbook I can give you to take home and I can also run off copies of extra practice. We are in this together. Let's BE SUCCESSFUL!

Also students please remember there are other ways to solve problems other than fighting. If you want to discuss this further I am available to talk.

Week in Review 9/24/10

What we did this week:

We learned the rules for multiplying and dividing integers first. The rules are this:
-When multiplying or dividing 2 numbers with different signs, the answer will always be negative.
-When multiplying or dividing 2 numbers with the same sign, the answer will always be positive.
So for example:
-10 x 4 = - 40
-6 x -9 = 54
It is important to not get these rules confused with the addition/subtraction rules. On Tuesday you created a foldable to help you learn these rules.
The addition rules are as follows:
-When adding 2 numbers with different signs, subtract the numbers (ignoring the sign), and then keep the sign of the larger number.
-When adding 2 numbers with the same sign, simply add the numbers (ignoring the sign), and keep the sign.
Example:
-5 + 8 = 3 (8-5 is 3 and 8 is bigger than 5 so the answer is positive)
-7 + -9 = -16 (9+7 is 16 and the sign is negative so the answer is also negative)

The subtraction rules go a little something like this:
-When subtracting 2 numbers you should remember this; KEEP, CHANGE, TAKE THE OPPOSITE.
You might also remember it like this; SAME, ADD, CHANGE (SAC).
Regardless what you are doing is changing the problem to an addition problem and then refer back to those rules to solve.
Example:
4 - (-7) = 11 (Same, add, change; 4 + 7 = 11)
7 - 17 = -10 (Keep, change, take the opposite; 7 + -17, subtract and keep sign of larger number; 17-7=10 and 17 is bigger than 7 so answer is negative.)

Students it is very important that you understand these rules and how to use them. If you practice these you will understand them.

On Friday we studied some word problems and identified key terms that help us work these word problems. You were then allowed to create your own word problem for an opportunity to see your problem on a benchmark as extra credit. I will collect these on Monday.

Report card grades will be due on Friday so make sure you have everything turned in. You should know before Friday if you are failing my class or even if you have below a 75. Let's get those grades up and remember to DO WORK AND STAY FOCUSED!

Week in Review 9/17/10

It was so great to meet so many of your parents this week. Students keep up the great work in my classroom. Progress reports will go out in a little over 2 weeks so you need to be sure you are doing your best always.


Parents and students be aware that I will now be assigning after school detention to students that can not correct wrong behavior in my classroom. These will require a parent signature and if you fail to show up you will receive a referral.


Now for what we did in class this week:
Monday and Tuesday we reviewed and took our first CCA. Those of you who did not pass should be completing test corrections to turn in by Tuesday. This goes for the benchmark you took a couple of weeks ago as well. Test corrections must be on a separate sheet of paper and WORK MUST BE SHOWN! I will not give points back if there is no work shown.
Wednesday and Thursday we studied how to multiply and divide INTEGERS. Remember that INTEGERS are the set of whole numbers and their opposites. Some examples are: 5, -5, 10, -10, 3, 4, -200.
The rules for multiplying integers are this:
A negative times a positive is a negative.
A positive times a negative is a negative.
A negative times a negative is a positive.
A positive times a positive is a positive.
In other words, integers with the same sign when multiplied will be positive. Integers with different signs when multiplied will be negative.
My students created some really good handouts on this topic that I can not wait to display on my Brag Wall. I hope to do more jigsaw activities like this one. I think it is a great way for you to learn, by exploring ideas on your own and creating something from it.


Friday we worked on some word problems so that we continue to build on our problem solving skills. These are very important to have in life and will also be very useful on the TAKS test. Remember that math with words should not scare you, just take it slow and read the question carefully.


Hope you had a great weekend and are ready for more learning in and out of the classroom.
