More Proportion Help

WKU stands for Word Ratio, Known Ratio Unknown Ratio.  Using this method when solving proportion problems will help make sure that you set up equivalent ratios that will make sense as you Cross Multiply an Divide.

The word problem states "The Rangers scored 3 runs in the first inning.  If they continue at this rate, how many runs will be scored in the entire game without any overtime?"  After we read through the problem, we go through and circle the words that we are comparing, in this case runs and innings. This is our WORD ratio.  We then continue to read the problem to find our KNOWN ratio, in this case 3 runs in 1 inning.  We have to use what we know about baseball to know that a regular game has 9 innings and we are trying to find the number of runs in those 9 innings.  To do this we place a variable in the UNKNOWN ratio.  We then cross-multiply and divide to find our answer of 27 runs in 9 innings.

Here you can also watch a video of me reviewing this with one of my STAAR Classes.  Enjoy! Leave me a comment! :)

Ratios and Proportions

We are still moving on with our Ratio and Proportions unit.  Please take time to go and watch the videos that I put in the last blog post.  If you do a 3-2-1 response on the blog, you can get 10 points extra credit.  YOU MUST WRITE SOMETHING MEANINGFUL in your response!


There is also some practice that you can do as well:

Moving on in Pre-Algebra

Today we finished up our benchmarks and we will be checking them together in class on Tuesday/Wednesday.  Starting on Thursday we will be covering Ratios and Equivalent Fractions.  I will not be in class on Thursday and this will be an investigative lesson so that students are working in partners together to discover the material.

I have found some videos below that cover the new topics.  Remember a 3-2-1 response left on the blog is worth an extra 10 points.  To receive the extra credit, you must respond by Friday, October 14th.  All comments left after that day will not be considered for extra credit.

Simplifying Rates and Ratios
Introduction to Ratios
Ratio Problem with Basic Algebra
Writing Proportions

Please continue to work on your number operations (fractions, decimals, percents, ordering numbers, basic operations with decimals, etc.) at home.  These are crucial and we are still seeing a lot of weakness in this area.

News 2 You 10/7

Journal: If you were given a $100 bill today, what would you spend it on and why?

After going over the writing stages yesterday, you know what your due dates are.  You are on your own for getting assignments in over the next two weeks!  Stay on top of things!

News 2 You 10/5

Journal: Today, I want you to first go and answer the anonymous poll about who you think should be our Newspaper Editor.  Based on the results of the poll, I will choose 2 students to be the editor.  We will start filling out some roles in the class as we keep moving on.

Next, I want you to write in your spiral 7-10 sentences answering the question, "What is the difference between school and life?"

Assignment: First, you will need to complete your Webquest.  You will then need to print off the papers that go with the webquest and staple them together.  This is your first test grade this Six Weeks.

When you finish the Webquest and have turned your papers in, you will need to make sure you have completed your 5WH.  I will be checking them tomorrow to give you a participation grade.

The last thing that you will need to work on is you will begin doing research for your assigned topic.  Based on your list from Monday, the editors will be choosing who will be writing on each topic.  This is part of their responsibilities.

Create an outline of what you will address in your topic together with your partner.  This will be due by Friday.

Need Some Practice?

I found a great site for extra practice on some of the stuff we have been doing in class.  Please check out Precision Teaching Resources.  You will not only get the worksheet for some practice but it will also have the answers so that you can check them when you are done.

If you do any of this work at home, let me know as I would love to see it! :)

Tuesday and Wednesday 10/5-10/6

We are testing on Tuesday and Wednesday.  Make sure that you have your Study Guide to turn in.  This will be given for a participation grade depending on the amount that you completed.  You had plenty of time in class on Monday and then Monday night to finish this.

Also, on Thursday and Friday we will be benchmark testing.  At this point we are seeing quite a few struggles with what we are teaching and haven't gotten into the true 8th grade material.  We need to find out where the problem lies and what to do about it before we can move on with our material.

Please get a good night of sleep and relax on benchmark days.  This is not there to stress you out but to determine your achievement level.
