Straight lines are use to illustrate the linear relationship between TWO variables / unknowns.
We have also been creating straight lines using Geo-Gebra.
How do we differentiate one straight line from another?
What are some of the properties that will cause one straight line to be different from another.

A Thinking Question....
When 1 is divided by 1, the answer as we know the answer will be 1. Similarly when 2 is divided by 2, 3 is divided by 3 and 4 is divided by 4, we know that the answer will still be equal to 1.
However, is it true that when x is divided by x, the answer will always be 1? If not, when is x divided by x not equal to 1?

Reflection on Solving of Linear Equations
Dear 107s,
We have started on with the solving of Linear Algebraic Equation last week.
Let us now do a quick recap of the important ideas that we have learn using the Wall Wisher.

Chapter 9.2 : Average Rate (Lesson 1)
Rate is a ratio between two quantities with different units of measurement.
Rate allows us to express a quantity as a proportion of another quantity thus enable us to make comparison between different quantity.
Examples of rate being used in our daily life are:
1) Speed of a car, where the distance is measured against time (Kilometer per Hour or Meter per Second)
2) Buying of food and drink, where the price is measured against the weight or volume (Dollars per Kilograms or Dollars per Litres)
3) Frequency of Buses (Number of buses in operation per Hour)
4) Heart Rate (Number of beat per Minute)
The examples of rate in our daily life in countless.....
Thus give 2 examples of the use of Rate in your life and briefly describe how you can make use of these information to help you make better decisions in your life.
Please also refer to your Textbook 1B from Pg 9 to 11 and your Ace - Learning Portal for more materials and examples.

CHapter 5.1 : Like Terms and Unlike Terms
Dear 107s,
We are back into our study of Algebra....
Like English & Chinese, Mathematics is another form of communication between people and Algebra is an essential part of this language.
Thus, let us now get to find out more about the Algebraic Language...

Chapter 16 : Data Handling Lesson 4
Dear 107s,
We are still looking at Statistics at the moment.
Often when we compare data, we heard about people comparing the MEAN, the MEDIAN and the MODE.
Thus what does this terms actually means?
Do an online search on the meaning of MEAN, MEDIAN and MODE and input the meaning under the comment section. Please also include in examples on how to determine the MEAN, MEDIAN and MODE in a data set.

Chapter 16 : Data Handling Lesson 3
Dear 107s,
Welcome back after the second round of Data collection along Clementi Ave 6.
Here are some of the tasks we are going to complete by today.
1) Uploading of data collected.
Please access the spreadsheet titled "SST 2010 Traffic Data Combined" through the Mathematics Google Site. Only the team member nominated for Data input during the last session can edit the table. The rest of the team members please helped to consolidate the data for your team mates.
2) Examples of Statistical Diagram (Bar Chart, Pie Chart & Line Graph) found in daily life
The wallwisher is an online Post-IT board.
Find one example of either a Bar Chart or a Pie Chart and another example of a Line Graph. Give a short descriptions on the diagram you have selected.

The History of Numbers (15 January 2010)
The use of numbers has started since the ancient time till now.
In your groups,
1) List out some of the Ancient Civilizations that have once existed in our world.
2) Decide on one Civilization that your group has listed out and carry out a research on the number system that was associated with this civilization.
3) Using a 5-slides Keynote presentation, develop a presentation that describe the development history of this set of number system, describe the number system and depicts digit from 0 to 9, the number 10, 100 & 1000.
4) Hence, develop a simple worksheet using Pages, which required your friends to convert numbers from your choice of number system to our present Hindu - Arabic number system. You should have 4 questions that involved a 2-digits number, 4 questions that involved a 3-digits number and 2 questions that involved a 4-digits number.
5) Please submit your presentation slide and worksheet by 25 January 2010.
6) Please acknowledge all information that the team has taken from the Internet. The method of acknowledgement is (a) The Title of the website. (b) The URL. (c) The Date and Time where the information was view.
