38 A large cube is constructed from individual unit cubes and then dipped into paint. When the paint has dried, it is disassembled into the original unit cubes. You are told that 486 of these unit cubes have exactly one face painted. How many unit cubes were used to construct the large cube? How many of the unit cubes have …. two faces painted, three faces painted, no faces painted?

39 As teachers of mathematics, we want our students not only to understand what they think but also to be able to articulate how they arrived at those understandings. (Schuster & Canavan Anderson, 2005

40  We need to unpack outcomes and develop rubrics for all 3 courses.  We will try to share the work-load across the teachers.  Supports available ◦ Templates (Curriculum Corner or handouts) ◦ Curricular Documents (online or in print) ◦ Textbook Resources  Please forward completed documents to myself for posting on Curriculum Corner.

41 Contextualization and making connections to the experiences of learners are powerful processes in developing mathematical understanding. When mathematical ideas are connected to each other or to real- world phenomena, students begin to view mathematics as useful, relevant, and integrated. (FM 20 – Page 15)

43  We have until 2:15 pm.

44 Outcome FM 20.7 Demonstrate understanding of the interpretation of statistical data, including: confidence intervals confidence levels margin of error. Note: It is intended that the focus of this outcome be on interpretation of data rather than on statistical calculations.

45 Opinion polls from a sub group (sample) of a larger population Quality control checks in large scale manufacturing / production lines

46 A poll determined that 81% of people who live in Canada know that climate change is affecting Inuit people more than the rest of Canadians. The results of the survey are considered accurate within ±3 % points, 19 times out of 20.

47 A cereal company takes a random sample from their production line to check the masses of the boxes of cereal. For a sample of 200 boxes, the mean mass is 542 grams, with a margin of error of ±1.9 grams. The result is considered accurate 95% of the time.

48 TORONTO (Reuters) - The Conservatives have a lead of about 9 points over the Liberals in an opinion poll released on Saturday, April 11 hovering around levels that could give them a majority in the May 2 federal election. The Nanos Research tracking poll of results over three days of surveys put support for the Conservatives at 40.5 percent, barely changed from 40.6 in Friday's poll. Support for the main opposition Liberals was at 31.7 percent, up slightly from 31.1 percent, while the New Democratic Party fell to 13.2 percent from 14.9 percent. The daily tracking figures are based on a three-day rolling telephone sample of 1,001 decided voters and is considered accurate to within 3.1 percentage points, 19 times out of 20.
