©Marian Small, 2011 If you are having audio issues, please go through these steps: 1.Check that mic is not muted or turned down often volume control is on plastic piece on headset wire, volume and mute may be separate controls 2.Check that headset and speaker prongs are in the correct holes in your computer 3.Make sure that you do not have separate external speakers plugged in If you do, please unplug them 4.Check that internal computer volume is not muted Start  control panel  sound & audio devices 5.Go through Audio set up wizard in Elluminate Tools  audio  audio set-up wizard 6.If your head set was plugged into front of computer, try plugging it into back of computer (or vice versa) and repeat Audio set-up Wizard 7.Throw computer out the window ( haha kidding!! )

Big Ideas for 4 – 6 Math Session 4 Developed by ERLC/ARPDC as a result of a grant from Alberta Education to support implementation

©Marian Small, 2011 Big Ideas Session 4

©Marian Small, 2011 Continuing with.. Tonight we will finish our work with probability and complete our series talking about big ideas in shape and space for Division 2.

©Marian Small, 2011 Probability Grade 5- verbal comparisons of likelihood Grade 6- experimental/theoretical probability

©Marian Small, 2011 Using probability language Choose which is most likely about a new student joining a Grade 5 class: A: The new student is a boy. B: The new student is the same age as lots of other kids in the class. C: The new student lives lives in the area. D: The new student is human.

©Marian Small, 2011 Now… Draw or write something that fits each category on the following slides: Almost certain Impossible Very likely Very unlikely

©Marian Small, 2011 Almost certain

©Marian Small, 2011 Impossible?

©Marian Small, 2011 Very Likely

©Marian Small, 2011 Very Unlikely

©Marian Small, 2011 A Big Idea

©Marian Small, 2011 You just flipped a coin and… You got H H H H H H H H H Vote: √ if you think a H next time X if you think a T next time

©Marian Small, 2011 Experimental probability You are going to describe an experiment using ONE spinner. The result you want should happen ABOUT three-fourths of the time. Which spinner would you use? Some choices are on the next screen.

©Marian Small, 2011 Choices A:B: C:D:

©Marian Small, 2011 Does your vote change? A:B: C:D:

©Marian Small, 2011 Big Ideas

©Marian Small, 2011 Measurement

©Marian Small, 2011 You might ask How could you measure a pumpkin? Raise your hand with a suggestion.

©Marian Small, 2011 You might ask Can you think of a measure you think most others won’t think of? Raise your hand or type in the chat box.

©Marian Small, 2011 Big Idea

©Marian Small, 2011 An interesting question I am thinking of a shape with an area of 36 cm 2. Which do you think is true about it?

©Marian Small, 2011 An interesting question A: It is probably a square. B: It is probably a rectangle, but not a square. C: It is probably very long and thin. D: I have no clue what it looks like.

©Marian Small, 2011 An interesting question A: It is probably a square. B: It is probably a rectangle, but not a square. C: It is probably very long and thin. D: I have no clue what it looks like. Can it be A, B or C?

©Marian Small, 2011 An interesting question Suppose I tell you that the 36 cm 2 shape is a square. Now which of these things do you know about it? A: the side length B: the perimeter C: the diagonal length D: all of the above

©Marian Small, 2011 Big Idea

©Marian Small, 2011 Or you could ask How many measurements do I need to give you so that you can figure out the perimeter of a rectangle? A: 1 B: 2C: 3D: 4 I’ll ask some of you to explain.

©Marian Small, 2011 Relating the yellow to the green

©Marian Small, 2011 Big Idea

©Marian Small, 2011 Or it could be… Rectangle B is twice as long as Rectangle A. They have the same width. A B

©Marian Small, 2011 Or it could be… What do you know, for sure, about their areas? Raise your hand.

©Marian Small, 2011 Or it could be… What do you know, for sure, about their perimeters? Raise your hand.

©Marian Small, 2011 Same Area Two rectangles have an area of 12 cm 2. They look very different. Sketch what they might look like on the next blank slide.

©Marian Small, 2011

The big idea is…

©Marian Small, 2011 Another example… I am thinking of a triangle. One angle is really small. One angle is close to a right angle. What do you know about the other angle? Raise your hand to respond.

©Marian Small, 2011 Which formula Here is a rectangular prism. Which is the best way to get its volume? A: Build a structure and count cubes. B: Multiply 5 by 6 x 8. C: Multiply 6 by 5 x 8. D: Add

©Marian Small, 2011 Big Idea

©Marian Small, 2011 Or for areas You only have a ruler and no other tools. You want the area of this rectangle. Area is how many squares are inside. Can you figure it out with just your ruler?

©Marian Small, 2011 Perimeter You multiply one side length by 2 and another by 2 to get the perimeter of a shape. What could the shape look like? Draw it on the next blank screen.

©Marian Small, 2011

Could have been a rectangle, a parallelogram, a kite Could it have been a square or a rhombus? Click √ for yes and X for no.

©Marian Small, 2011 What do you think? For a certain situation, you think it might be really good to use millimetres as a unit. What might that situation be? Raise your hand or type in the chat box.

©Marian Small, 2011 What do you think? For a certain situation, you think it might be really good to use millimetres as a unit. What situation would it NOT be? Raise your hand or type in the chat box.

©Marian Small, 2011 A Big Idea

©Marian Small, 2011 If you changed your mind and used centimetres, could you easily figure out the number if you knew the number of millimetres?

©Marian Small, 2011 Big Idea

©Marian Small, 2011 What units ? What units could fill in the blanks? 2000 ____ = 2 _____ Type the units (in a pair) on the next screen.

©Marian Small, ___ = 2 ____

©Marian Small, 2011 Which angle is about 50°? A:C: B:D: Vote.

©Marian Small, 2011 But how did you know?

©Marian Small, 2011 Geometry

©Marian Small, 2011 parallelogram, trapezoid, rectangle, square, kite, rhombus All the sentences must be true. Use each word once. A _____ is a special ______. Two shapes that might have equal sides that touch are a _____ and a _______. Two shapes with a square corner might be ____ and ____.

©Marian Small, 2011 Big Idea

©Marian Small, 2011 Another example How many measurements do you need to take to figure out if this triangle is really a right isosceles triangle? √: 2 X: 3

©Marian Small, 2011 Parallel edges What can you do to be sure which edges of this prism are parallel?

©Marian Small, 2011 Describing Shapes Type in the chat box to describe properties of this shape.

©Marian Small, 2011 Big Idea

©Marian Small, 2011 Another example I am thinking of a shape. It has no edges that are parallel. What could it be?

©Marian Small, 2011 How do you move? I used one or more transformations to move from the green square to the blue square. What could I have done? (Vote on next slide.)

©Marian Small, 2011 How do you move? A: two rotations B: one translation C: one reflection D: one rotation

©Marian Small, 2011 Big Idea

©Marian Small, 2011 What do you think??? Why do you think it might be a better idea to use shape A to model all three transformation effects than shape B? Raise your hand to reply or type in chat box. A B

©Marian Small, 2011 Big Idea

©Marian Small, 2011 I moved a shape… How do the coordinates of the shape change after the transformation?

©Marian Small, 2011 Big Idea What do you think the big idea is?

©Marian Small, 2011 Sharing Time I hope some of you have stories to share.

©Marian Small, 2011 Thank you It’s been an interesting ride. I know a webinar is a different experience than face to face, but hope it proved useful to you.
