Sept 17

More discussion of the locker problem today -
What lockers will the 37th person touch? (ALL MULTIPLES of 37)
Who will be the last person to touch 3 lockers? (Person #66, 200 divided by 3 is 66r2)
Which locker will get opened/closed the MOST times? Why are only the perfect squares open at the end?

Homework:
On the 1-200 number chart:
** Colour every third number
** Colour every multiple of seven a different colour
** Get a parent/guardian to sign the blue Course Outline sheet

The number chart will be the basis of a discussion we will have in class on Monday.
(This is the one time during the year you are welcome to do your homework while watching TV or talking on the phone... if your parents don't believe you can direct them to this blog)

** I have also handed out a few "Advanced" problem sheets. During the year I will copy bonus material on off-white paper. You can work on these whenever you find yourself finishing work early... or in those moments when you feel your life just needs more Math.
