# MPM1D More Composite Figures Practice 2017-12-14

Here is the extra practice work that several people requested:

Looking for answers to check your work? Here they are! (Message me if I made any mistakes, okay?)

# MPM1D myBlueprint and talkin’ bout homework 2017-12-12

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
• diameter
• centre
• chord
• arc

You should also know these relationships:

$d = 2\pi$

$C = 2d$

$C = 2\pi r$

$A = \pi r^2$

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

# MPM1D Finishing optimization; drawing 3D figures; Math RPG 2017-12-07

We wrapped up yesterday’s work on optimizing area and perimeter for rectangles.

I handed out the Math RPG that we’re going to use for homework and “academic behaviour” tracking – see my other blog post about it if you want to hear more.

We started to practise drawing 3D figures using isometric dot paper (PDF here).
