Cartesian Plane

By the end of Grade 5, you are expected to be able to:

Apply the language and notation of bearing to describe position and direction.

Cartesian coordinates are way of describing position using numbers. They are plotted on a plane that can have 1 or 4 different quadrants.

The invention of Cartesian coordinates in the 17th century by René Descartes (Latinized name: Cartesius) revolutionized mathematics by providing the first link between geometry and algebra. Using the Cartesian coordinate system, shapes (such as curves) can be described by Cartesian equations: algebraic equations involving the coordinates of the points lying on the shape. (http://en.wikipedia.org/wiki/Cartesian_coordinate_system)

Your task:

  1. Discuss with a partner and share with your class the following: How do the four quadrants of the cartesian plane work? (Teacher, project the images onto a whiteboard so you can write over it)
  2. Play this game 3 or 4 times. 
  3. Play this game 3 or 4 times. 
  4. Draw a cartesian plane that goes from 10 to -10 on both the X and Y axis in your maths book. Make sure to write your numbers ON THE LINES and NOT in the spaces! 
  5. Mark the following coordinates on your cartesian plane. Use the letters given. 

 A) (3,4)        B) (6,2)        C) (4,0)        D) (0,8)        E) (-2,5)

 F(-4,7)       G) (-3,0)       H) (-8,3)       I) (4,-9)       J) (3,-5)

 K(6,-2)       L) (0,-4)       M) (-3,-6)     N) (-8,-1)      O) (-5,-6)

6. Do exercise 14:2 starting on page 199 of the blue text book. (Note, in maps, we only use the first quadrant of the cartesian plane)

Exhibition day has passed and now it is time for you to write one last entry for your Exhibition journals.

This is your last opportunity to score full marks on your Exhibition Weekly Blog Rubric.

For this reflection, you will not be provided any questions, however the focus of the post should be on your reactions to last night, what you’ve learned and anything you’d change.

Puberty research – Just Around the Corner and Brainpop

There are a number of ways to approach the research task. (The diagram below refers to the Pre/post assessment chart found HERE)

Method 1:

  1. Watch the ‘Just Around the Corner’ videos for boys and girls as a whole class.
  2. Watch them again as a whole class, this time thinking about a question that you are wondering about and some key words you might want to listen for.
  3. Get your diagram back from your teacher, and add anything new you found out in a different colour pencil to the first time you recorded on it.
  4. Individually, watch the Puberty Brain Pop movie. Make sure you view the related topics (reproductive system, acne, period and growth) as well.
  5. In a different colour, record what you learned on your diagram.
  6. Hand your diagram back to your teacher.
Method 2:

Boys individually on your laptops:

  1. Watch Just around the corner for boys video twice
  2. Watch Just around the corner for girls video twice
  3. Watch this Brain Pop
  4. Get your diagram back from your teacher, and add anything new you found out.
  5. Hand your diagram back to your teacher for safe keeping.

Girls individually on your laptops:

  1. Watch Just around the corner for girls video twice
  2. Watch Just around the corner for boys video twice
  3. Watch this Brain Pop
  4. Get your diagram back from your teacher, and add anything new you found out.
  5. Hand you diagram back to your teacher for safe keeping.
