Wednesday Proportion Test Preparation

On Friday you will have your first test of the year.  Tests are longer and more difficult than quizzes.  Please study hard.  Your test will have 2 parts, Multiply Divide and Fraction Warmup NO CALCULATOR, then a Ratio, Rate Proportion Test where you can use a calculator.  Please make sure you are playing Manga High and studying for this test.

Today's Warmup

We will continue to review tomorrow.

Greetings from Kelowna

Yesterday I ran the BMO Kelowna Marathon. It was a beautiful day and my time was 3:17.41(3 hours 17 minutes and 41 seconds).

If a Marathon is 42 kilometres, what was my average pace per kilometre?

A marathon is also 26.2 miles. What was my average pace per mile?

A cross country loop is approximately 1.2 kilometres. How many loops make up a marathon?

What pace would I hold for each of those x-country loops?

See you all on Wednesday. Ratio,rate and Proportion Test on Friday or Monday depending on interruptions.

X-country running

We have done many classes on running.  We are winding this unit down over the next two weeks.  One of my objectives was to see how far the Cross Country Team could run during their season.  Working on this will be our questions today.

How far have runners trained in your room since the beginning of the year?

How far have runners trained in Grade 8?
How far have runners trained in Grade 7? 
How far have runners trained in Grade 9?

How many total kilometers have all the runners run since the beginning of the training season?

Where is Auburn Ontario? How far is it from Winnipeg to Auburn?

Where is Bellville Ontario? How far is it from Winnipeg to Bellville?

Once you have collected your data you need to write the following:

• 6 part to part ratios
• 3 3 part ratios
• 6 part to whole ratios
• 6 part to part to whole ratios

Here is a video on Ratios.

Here is your homework for the long weekend.  Do the homework book pages 12,13,14,15 and the following two questions.

How do we check these proportion statements to see that they are correct.

Also using your running and walking 10 m information do the following work.

Comments at the blog please.

What is your running stride length?

http://www.flickr.com/photos/drewgeraets/5074539994/

Last class we calculated our walking stride length.  Today we need to calculate our running or jogging stride length.  Here is your assignment.

1. What is your walking stride length?(size of one walking step)
2. What is your jogging stride length? (size of one jogging step)
3. How many strides does it take to walk 100 m?
4. How many strides does it take to jog 100 m?
5. How many strides does it take to run 100m?

How many strides does Usain Bolt take to run this race? What was his average stride length?




All questions need to be answered using a proportional statement.  Please include a word ratio and the appropriate math work.

Stride length math

View more documents from spmath.

Good luck.

What is your walking stride length?

Today in class we learned about proportional statement.  In each statement you needed 2 equivalent fractions (ratios).  You showed how to prove they were equivalent 2 different ways.

Using the information from today's class please figure out the length of just one stride or stride length.

Remember that there are 80 squares in the sidewalk, each square is 145 cm  and the total sidewalk is 11600 cm.

 
You counted your number of steps or strides, you know how long the sidewalk is so.... how far is one stride or your stride length ?

Please leave your answer in the comments below this blog post and in your notebook:)

His computer will send a signal back to his home planet unless you type in how to solve 3 proportional reasoning questions.

To help you out use 3 problems from pages 67, 68 or 69 in your textbook.

You need to explain how you solved the questions using pictures and diagrams (show the ratio tables or equivalent fractions you used).

The assignment one more time.

1. title it How I stopped an Alien Invasion using  Proportion  (make a better title if you want)
2. Label it alienstory, proportion
3. Include 3 problems from pages67, 68, 69 in your textbook.
4. Have fun creating a great story but it is secondary to the math knowledge you need to show. 
5. If you want to include pictures you can use this site to look for interesting images.  Remember when you use images to cite them properly and only use images you are allowed to. (cc or creative commons)
6. Flickrcc or you can try compfight but make sure you have the creative commons search on.
   

Have fun finding pictures that make your story better.  Some of the best searches happen when you search for pictures of adjectives or adverbs.

This is due Monday.
