Art – Today, we finished our Haida art pieces. They turned out very well! Any students who were unable to finish will finish next week.
French – After this, the students had French with Mme. Stella, which you can read about on her blog (https://stjudesfrench-stella.blogspot.com).
Gym – After recess and lunch, the students had gym with Mr. Orr, which you can read about on his blog (http://tysonorr.blogspot.com).
Inquiry into Language – Today, we worked on choosing reasons for our speeches to support our arguments. Yesterday, students worked on finding five reasons to support their argument. Today, we tested the quality of those reasons and worked on choosing the three strongest reasons to support our arguments.
Inquiry into Math – We started by taking up the homework from yesterday on line graphs.
Today, we started looking at the real-life applications of our measures of central tendency – mean, median, and mode.
We started by looked at an example of clothing sales in a store in our textbook, and then began the lesson by doing an example together. Throughout this, we looked at why we would use these in actual real-life situations. For example, mode in a clothing store could tell us which sizes are purchased the most, telling store owners what to order.
At the bookfair, here are the number of young adult books sold at each price range:

What is the range? à 38 – 9 = 29, the range is $29.
What is the mean? à
(9 x 4) + (10 x 5) + (14 x 5) + (33 x 2) + 38
= 36 + 50 + 70 + 66 + 38
= 260
260 ÷ 17 = $15.29
The mean is $15.29
What is the median? à The median of 17 numbers is the 9th number, which is $10.
What is the mode? à 10 & 14 occur the most, so the modes are $10 & $14.
Which measure of central tendency best represents the average price of a young adult book? à
Mean is not a good representation here because only 3 books are higher than the mean and 14 books are lower than it. There are two mode prices, one of which ($10) is the same as the median. There is a balance of books above and below the median price. Therefore, median would be the best measure of central tendency in this case.
Over this weekend, students will work on this lesson homework and the mid-unit review to prepare for the test next Friday.
Homework:
We do our best to complete work in class. In the event this is not possible, it will go home for homework.
As always, please feel free to email me with any questions.
