Isometric Drawing


1.
http://www.mathplayground.com/cube_perspective.html
Open the above link and play the game.

2.
There are ten puzzles to be solved.
On the main entry page, go to “Building with 3 Sides” and then choose the figures to do (there are 10 puzzles). You can move the grey grid square around to help you do views.
Once you play around and get used to how build mode works, it is a lot of fun.

Important tip for beginners – Build the top view onto the base mat first, and then work upwards from there.

Math Champ Math POW - due Fri., Oct. 31st
























Post a response explaining how you solved the problem and justify why your problem-solving strategy is the best one to use.  The winner of the "Math Champ" title will be the student who can explain his or her strategy with the greatest clarity and detail.  (Although you may prepare your answer at home you will not post your answers until Friday, in class.)

David's Response
A:
  1. Well, Ivan would sell the greatest amount of chocolate bars. Ivan already has double the chocolate bars of Sonia, and 5 days isn’t much to make progress, she would only have $28 in total (12+(4 x 4)=28), while Ivan would have $32 ($24+(4 x 2)=$32).The difference would be four, 32-28=4
  2. They would have the same same value of chocolate bars on the 7th day. For Ivan, it would be (24 + (2 x 6)=36) and for Sonia, it would be (12 + (4 x 6)= 36)
  3. Sonia’s total would be 10 more than Ivan’s total on the 12th day. Sonia’s total would be (12 + (4 x 11)=56) while Ivan’s would be (24 + (2 x 11)= 46). 56 is 10 more than 46. An easier way to do that would be when they both were at 36, on the 7th day, then Sonia would be (36 + (5 x 4)=56) and Ivan would be (36 + (5 x 2)=46) since Sonia had double the production capability, and since there were 5 days and Sonia produced $4 dollars every day (in five days she would make 4 x 5=$20) and Ivan made $2 (in five days he would make 2 x 5=$10).

My strategy:
My strategy was to make a table of what Ivan and Sonia made every day, and I listed all the days that needed for my calculations, and I also listed the amount of money that each person made each day, as well as their total with it. I calculated this doing it with multiplication, then checking it with the chart. I then used the information I had and confirmed it with 2 references, my list of days and the amount of money, as well as the multiplication. I could have used the multiplication, then the list as a reference, but I found that sometimes when you list things out, you can avoid some tiny calculations that you might not think out clearly when you don’t write it down.It was the best because it was efficient, didn't take much time but it was really detailed. I showed everything I did, and I showed the math clearly. That is why my strategy was the best. (It says to explain why yours is the "best", I wouldn't say mine was the "best" if I didn't need to)

In-Class Math POW -due Friday


Math POW Solutions

























































EQAO Math Review - Including SOME examples

For Gr. 6 -

Here are the topics we have covered in Grade 6 Math.  If you have any areas you need to work on now is the time to practice and review.  Use the EQAO practice tests to help you.  We will be reviewing each of these areas.  You will be assigned a review topic for the rest of the class and I will post your review on the blog for students to study.  (Two students are already working on an Area and Volume Review.)

1. Prime and Composite Numbers and Factors
Prime Numbers – have only 2 factors (numbers that can divide evenly into it) – 1 and itself
Examples of Prime Numbers – 1,2,3,5,7,11,17,etc.
Composite Numbers – have more than 2 factors
Examples of Composite Numbers – all even numbers except 2 - 9, 15, 99, etc.
2. Data Management Graphing
Finding Mean, Median and Mode, Range, Scale,  Bar, Broken Line, Stem and Leaf Plot
3. Patterning & Algebra
4. Number Sense – Reading big and small numbers
5. Measurement Conversion
46 m = 0.046 km
Converting square and cubic units - 1 m2 = 10 000 cm2/ 1m3 = 1 000 000cm3
6. Area and Volume
Formulas!



7.  Measuring Angles (acute <90, Obtuse >90 and reflex>180)
8. 2D and 3D Shapes 
Drawing 3D shapes on isometric paper and top/side/front view – draw 2D shapes using angle measurements
9. Probability 
Using fractions and percent
http://www.mathsisfun.com/data/probability.html
10. Fractions, decimals and Percent
Know how to convert - 40% of 90
Extra Support - https://goo.gl/fb1agz
