11U - Final Exam Review Solutions Posted

Hello all,

Ms. Wong completed the solutions during her lunch and last period, so I put them up on the website. Hopefully somebody sees this and spreads the word; had I known she would write solutions I would've informed you all in class.

Study hard and best of luck tomorrow.

Grade 11 Functions - Units 6 & 7 Solutions Are Live!

Enjoy the rest of the weekend. Prepare yourselves for the MATHmagical Kingdom on Monday; you won't be the same afterwards.

MCR 3U1: Exam Review Posted

For units 1-5. Units 6 and 7 coming by Sunday at noon. Unit 2 is sideways because it's the only way it would fit through the scanner. Unit 4 & 5 has a grade 10 quiz, as I wrote the last page on the back of scrap paper. An entire forest was saved as a result.

Reminder: summative on Monday for units 1 - 4. This is how it goes:

1) Sit individually, get the summative and keep face down.

2) 2 minutes to read through it silently and independently.

3)10 minutes to talk with your classmates about how to complete the questions. During this time, you may only have your blank summative and yourselves. No resources, calculator or writing utensils.

4) Go back to your seat, and write the summative. You have access to your textbook ONLY during this time.

Have a good weekend.

UPDATE: grade 11 average temperatures

Hello grade 11's,

Type in your city name, and "climate". e.g. "Toronto climate". A periodic graph will appear, and there is an option when you click "more", and a table with average temperatures will appear.

Hope this helps.

Grade 11 Weather Assignment Data

Hello grade 11's:

Hope you enjoyed sleeping in on a Friday. I poked around wolframalpha and there isn't a way to get all monthly temperatures in a single table.

What I would do is query something like "Toronto monthly mean temperature 2010" and print out the resulting website.

Simply query each month and get the average temperatures e.g. query "Toronto mean temperature January 2010" and average the high and low. Use that value. Please include a table that shows the numbers you are using.

Have a great weekend. You too grade 10's.

Tests Update

Grade 10 Academic: The unit test will go ahead as schedule for tomorrow. Study well tonight.

Grade 11 University: The unit test will be on Friday instead of Monday. Monday is conflicting with other engagements with a significant number of students, and we felt it was best that you write the unit test on Friday. Earlier the better.

See you all tomorrow, take care.

e-Textbooks

A lot of students have been asking me about accessing the course textbook online so you don't have to carry the book home each day.

Tomorrow in class I will give the passcode unique to our course so you can do this. Please remind me in-class in case I forget.
