Have You Travelled the World Lately?
Hello 9-05 and 9-06. I hope you are all busy getting ready for the test next week. I have just completed two copies of the test as you will be writing on seperate days.
For 9-06 your homework is to complete all Apply and Extend questions for Monday pages 60-62 I believe. You also need to check 9-05 blog to see how they have completed the work if you are having difficulty.
For 9-05, first spend some time on Feedjit and see all the places you have travelled since you have started blogging. It is truly amazing the corners of the world you have touched. Enjoy the trip.
Then, Blog post your question. Complete all Apply and Extend and if you are having a hard time give me a shout. I am also in the building tomorrow if you need help.
I also want you to try to complete the workbook section 2.2 and Extra practice 2.2. I will post answers to extra practice tomorrow or Saturday. (This is extra practice and I will not check to see if you have completed the work. Unless you fail the test.)

9-05 and 9-06 Homework
Wow what a crazy day for Mr. B! I think there were 40 adults that came through our math class today and that doesn't count the student teachers or for 9-06 Mrs. W. I'm very proud of the way you all handled so many teachers coming through the room during your classes. You all did a splendid job of staying focused and doing what you needed to do.
Here is your homework for the weekend:
9-06 All of 2.1 Extra Practise sheets and the Workbook pages for section 2.1, Journal
9-05 Your homework is CYU #1, 2, 3 Practise #4 or 5, #8 or 9, #10 or #11 or 12, 15, & 17
Apply #18 or 19, 20, 22, 23, 24, 26 and Extend #29 or 30, Journal
Just remember you get a long weekend but Mr. B. is off teaching teachers about math tomorrow. Thank you to all the students who gave me your "Stash Its" to show to other teachers. I chose only a few of you although I could have chosen many more from the class. Thank you again to all for making teaching so much fun!!
9-05 another challenge to you... Joseph posted a video about rationals. I would like someone in class or many of you to improve upon the Video. Who is up for the challenge? See me so we can discuss it. There are some mistakes in the video! Can you spot them?

Unit 2 Problems
Two Problems
1. A chessboard is a large square and is made up of 64 small squares. Consider only the first three rows of the chessboard.
a) Find the diagonals of all squares and rectangles possible in the first three rows. Arrange the squares and rectangles, from least to greatest, by length of their diagonals.
b) Consider the entire chessboard. When would you expect the squares or rectangles to give whole number diagonals?
2. A gold bar has a mass of 1 and 1/3 kg. You wish to cut off exactly 1/2 kg. What fraction of the bar should you cut off? Explain.
Problem 1 will require good organization, be conscientious in your work. Write the answers in your Journal to start and then later I will ask you to post.

Hello 9-06 and 9-05, I hope your weekend is going well. I have assigned work for you in class that you need to be working on over the weekend. I will list the work here later. I am still waiting to see ho will expand on the Babylonians. There are other questions I have asked that you should consider answering. It will help with one of our next units of study.
The work you need to complete for me by Tuesday is online in the student text. For those of you who do not have access I certainly hope you have a book from me.
CYU page 31 #1-3
Practice page 32 and 33 #5, 6, 7, and 9
Apply page34 #13 to 19
Extend one of 20 or 21 and one of 22 and 23 (For those who wish to challenge themselves and learn more)
Question # 11 I would like you all to blog on this question and let's see how big the list becomes....
Have a great weekend looking forward to discussing your work with you on Tuesday.

So...How do I Find Surface Area of a Cube? Rectangular Prism? Cylinder? Composite?
Hello 9-06 and 9-05, who can help me out? I'm trying to find the most elegant algebaric expression to help me to find the surface area of a cube, rectangular prism, cylinder, or a composite of any of these shapes. What about the surface area of a triangular prism? How does symmetry help us solve some of these surface area problems? What happens if a part of any of these shapes is missing? How do I find surface area then? Help me out and post what you know over the next few days. Maybe someone can make a movie to explain the process?? Looking forward to some fantastic posts.
By the way 9-05 http://spmath90509.blogspot.com/ your explanations for, "Why 360 degrees?" really rock!! Keep up the great posts. Our place value is ones (1), tens (10), hundreds (100), thousands (1000) etc. Did anyone find out what 60 looks like in the Babylonian number system? What would be the next place value and what does it look like? or the next? Is there an easy way to write these numbers using our number system?

Test Thursday and Why 360?
A reminder to all 9-05 and 9-06 students that we will be having a test on Line Symmetry and Rotation Symmetry use section 1.1 and 1.2 to study from.
9-05 we talked about why the number 360 was used to describe a full circle. Explain to 9-06 why this number was chosen.

Grade 9's Welcome
Hello grade 9's, welcome to our shared blog spot. I look forward to reading what it is you have to say about what you have learned during math class. I want this to be a resource for all of us. For you to help each other and for me to be able to understand how you are dealing with the topics covered. Let's make it a great site.
