## MFM1P – Dec 15, 2014

PLEASE NOTE:  WE HAVE A REVISED SCHOOL DAY SCHEDULE TOMORROW (DEC 16) FOR OUR CHRISTMAS MASS.  I HAVE POSTED A COPY OF THE REVISED SCHEDULE BELOW.

Christmas Mass Revised Schedule for the Day (Dec 16)

IMPORTANT:  THE STUDENTS WILL BE HAVING A UNIT TEST ON CHAPTER 6 (SECTION 6.1 TO 6.5 FROM THE TEXTBOOK) ON THUR DEC 18.  I WILL ALLOW THE STUDENTS TO HAVE A “CHEAT SHEET” FOR THEIR TEST ON THUR DEC 18.  THIS CHEAT SHEET IS 8.5″ BY 11″ (LETTER SIZE) DOUBLE SIDED AND THE STUDENTS CAN WRITE ON IT (NOT TYPED) WHATEVER THEY WANT (EXAMPLES, FORMULAS …ETC).  STUDENTS CANNOT PHOTOCOPY SOMEONE ELSE’S SHEET.  I WILL GIVE THE STUDENTS TIME IN CLASS ON WED DEC 17 TO WORK ON THEIR “CHEAT SHEETS”.

I began the class today by taking up any questions the students had from the homework I had assigned Fri Dec 12.  I took up a few questions using the board/digital projector from the worksheet titled “Slope from a Graph Worksheet”.  I also showed the students an example of rate of change which was Page 199 #1a from the textbook (I did this using the digital projector and black board).  After going over the homework, I then told the students that we would be doing a few lessons today.  I first did a lesson which was a continuation from Fri Dec 12 titled “6.3 Other Rates of Change (continued)”.  I went over the concept of slope again with the students.  I showed the students how to calculate the slope from a graph (slope = rise/run) and then I showed the students how to calculate the slope when you are given 2 points (slope = y2-y1/x2-x1).  After going over these concepts and giving the students some examples, I then moved on to the next lesson.  The next lesson I told the students was 2 of the sections from the textbook combined into 1 (I did this because the topics are related).  The title of today’s lesson was “6.4 & 6.5 Direct & Partial Variation”.  I showed the students how to tell if a linear relation is direct or partial from a graph, table of values and from an equations.  I told the students that I would continue with this lesson tomorrow and would give the students some more examples to help them with some of the more difficult questions.  I then assigned the homework for the students to work on for the remainder of the period (the worksheet titled “Slope from a Graph & Slope from 2 Points Worksheet” and Pages 207 & 208 #1 to 4).

Below you will find a copies of the handouts/worksheets that were distributed/assigned in today’s class.

Take-up of the homework from Dec 12 (Slope of a graph worksheet #5 to 8 and Page 199 #1a)

Dec 15 – 6.3 Other Rates of Change (continued)

Dec 15 – Lesson – 6.4 & 6.5 Direct & Partial Variation

Slope from a Graph & Slope from 2 Points Worksheet (with answers) (the students only have to do #1 to 16 from this worksheet)

Chapter 6 Linear Relations – pages 190 – 250 (Students are to do the following questions for homework – Pages 207 & 208 #1 to 4 – from section 6.4 Direct Variation)

Below are the answers for section 6.4.  Please note, for page 2, it scanned upside down, so in adobe acrobat click on view, rotate view and then clockwise to fix it.
