Math Homework

Here are the links you will need to watch to help with your math homework tonight.

Traditional and Grid Video


Lattice Method Video

Which method do you like the best? If you have extra time and this is easy for you, make your own video that shows all three methods together!

Reflecting in Math

How can you tell if a number is in scientific notation?

This is a great question and an even better assessment of what you know!

Math - Frequency and probability

How do you calculate the probability of an event? Think about how we calculated probability today and used that to make predictions.
Describe the connection between frequency and probability.

Dividing by 0.1, 0.01,...

Rotations in the Cartesian Plane

In class we found a few basic rules for rotating on the cartesian plane.
-we rotate in increments of 90 degrees
-ignore the shape and just focus on the points
-clockwise is a negative rotation
-counter-clockwise is a positive rotation

Here's a video that sums up what we have learned.

Geometry Culminating Task Due April 3rd

Culminating Activity: Grade 8

For this task, you are going to create a map of a city called PICK A NAME.  The civil engineer who designed PICK A NAME was obsessed with geometric relationships and made the streets cross to demonstrate various line, circle and angle relationships.  Create the detailed map. You must label all streets and the angles that they intersect. Be as creative as you can!

Your street map for PICK A NAME must contain the following:

•         At least 1 pair of parallel streets

•         Two streets that are transversals

•         Two intersections that have an alternate angle relationship

•         Two intersections that have a corresponding angle relationship

•         Two intersections that have an opposite angle relationship

•         One street that meets another to create a pair of supplementary angles.

•         A park that is a quadrilateral, with walking paths that meet perpendicularly

•         A Town Centre that has three quadrilateral buildings. Each building has a path to the centre.

	Level 1	Level 2	Level 3	Level 4
Knowledge: -         I understand how geometric properties can be applied to the real world. -         I included all required geometric properties.
Application: -         I created a street map that has angles that are geometrically correct. -         I solved angle relationship problems involving interacting lines, parallel lines, and transversals. -         I calculated complementary, supplementary, and opposite angles.
Thinking: -         I identified application of geometric properties in the real world.
Communication: -         I included angle relationships that complement each other accurately. -         I labeled all angles names, degrees, and geometric properties correctly.

Geometry Review Quiz

Geometry Site

For math tomorrow, we will be going on a quadrilateral hunt. You can bring in your iPod to take pics of the ones you find with your partner/group.

Here is a site from Ms.M about what we will be working on in math for the next few weeks.
