Round two: Google Sheet

Here’s your homework: 04 – Perimeter and Area of Composite Figures. Don’t spend more than 30 minutes!

We logged into myBlueprint and browsed around that service for the first 30 minutes of the block today.

Next I went through the homework questions with everyone, since lots of people found them difficult. A few more people took the practice work to try.

We spent the last 15 minutes refreshing our memories about circles. You should know the following terms:

- circumference
- radius
- diameter
- centre
- chord
- arc

You should also know these relationships:

For example, if you were told a circle has an area of 12 you should be able to calculate the radius, diameter, and circumference.

We spent the period learning about correlations in two-variable statistics.

Big concepts were the types of correlations (accidental, common-cause, cause-and-effect, reverse cause-and-effect), the correlation coefficient R, and the strength and “direction” of correlations.

We spent a bunch of time working with triangles today.
