T erm 3 Week 9
Complete 2 pie graphs using the data for the Home Group on minutes watching television. __Graph 1__ - To be done electronically using a spreadsheet on Excel and the pie graph option in Chart. Be sure to include a heading and a legend. __Graph 2__ - To be constructed by hand in your book. You will need to draw a circle accurately with a compass You will use a protractor to measure how many degrees each category represents. Remember, there are 360 degrees in a circle. If you converted the figures for each category into percentage the each 1% would equal 3.6 degrees. Accuracy is important. A heeding and legend is essential.

Need to understand these: Mean Median Mode Range State what each is for the television data we collected. Use the definitions on page 487 of your text book.

**﻿Term 3 Week 10** Home work sheet 4 is due. Both pie graphs need to be completed. There will be a test covering measurement, decimals, and converting them to fractions. There will also be a little on probability and tree diagrams. We will go over the graphs homework from last week so that you are aware of interpreting graphs and extrapolating graphs. Otherwise you will be able to get on to your ** environmental issue project **. This is an __integration project combining Humanities and Maths.__

**Please check out the following:**
**Environmental Issues Project** **Maths Rubric for the Envronmental Project**


 * Term 4 Week 1 **

Use the Official AFL Grand Final Match Stats to calculate Mean, median,mode and/or range.
====We will look at the Commonwealth Games medal Tally as a source of data. We will compare the populations of the countries leading the medal tally. Is it true that a bigger population is a key factor in how many many medals a country will win? What other factors are there. We will look at GNP per capita as another factor.====

===First homework sheet for term 4 handed out this week due next week. Remember to show me you completed pie graphs from last term. ===
 * Term 4 Week 2 **

We will learn what a stem and leaf plot is (sheet to complete) and time to complete the Maths part of your environmental project.


 * Term 4 Week 3 **

Students will demonstrate that they can accurately measure and then draw an angle using a protractor. Students will use Maths 300 site to develop skills in estimating angles. Students will take notes on these key terms: Right angle - 90 degrees Acute angle - less than 90 degrees Obtuse angle - more than 90 but less tha 180 degrees Sraight angle - 180 degrees Reflex angle - more than 180 degrees Students will measure the internal angle of some triangles to discover that they always add up to 180 degrees. Using this information students will find a pronumeral using right angles, straight line angles and triangles. Students will also take notes on these types of triangles: Equilatoral triangles Isosceles triangles Scalene triangles Numeracy On-Demand tests will take place for Greece and China.

** ﻿ ** We will look at the angle of roof pitches. St udents will draw a simple house with a 30 degree pitched roof the the same with a 60 degree roo pitch. Which one seems more realistic for houses today?.We will look at older style housing we can see the pitch of the roof was generally steeper than it is today. 20 degrees is commonly used today. We will measure the angle of the roof of an old house. We will take a look at the angle of the great pyramids of Giza.
 * Term 4 Week 4 **

Lets draw some triangles knowing SSS (side, side, side) 3cm, 3cm, 2cm, SAS (side, angle, side)2cm, 70 degrees, 3cm and ASA (angle, side, angle)40 degrees, 3cm, 70 degrees. Key ideas p 118 Essential Year 7 Maths.
