Are all straight lines the same?

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?

Welcome Back for a New Semester

Dear students,

Welcome back to school after your June Holidays.

Let us start the new semester with this task.

Under the comment section, post up

1) 1 interesting thing you have done / see during the June Holidays.

2) 1 interesting knowledge that you have learn during the June Holidays.

3) The expectation that you are going to set for yourself in the learning of Mathematics.

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 16 : Data Handling Lesson 4

Dear 104s,

Welcome back after your Common Test.

In statistics, we will will often analysis data set based on MEAN, MODE & MEDIAN

Thus, what exactly is mean, mode & median?

Do an online search and input your definition of mean, mode and median in the comment

Chapter 16 : Data Handling Lesson 3

Hi 104s,

Great to see everyone again after your data collection session 2.

Today we will have a couple of tasks to complete

1) Please upload your data collected from yesterday session into the spreadsheet "SST 2010 Traffic Survey Data". 

Please indicate clearly the direction of the traffic flow.

2) Examples of Statistics in real life.

We are going to make use of an online Post-It board to help us in gathering examples of Statistical digram that we can find in real life.

Everyone is required to put up 2 Post It, giving an example of either a Bar Chart or a Pie Chart and an example of a Line graph.

Chapter 16 : Data Handling Lesson 2

Hi 104s,

Congratulations on your completion of the first round of data collection.

 

Thus, I will like the class to reflect on your experience this morning.

Please post your reply under the Comments Section for the following questions.

1) What are some of the difficulties you have encountered during the data collection process?

2) What are some of the improvement you can make to the data collection process?

Chapter 16 : Data Handling Lesson 1.2

Data Handling is a major part to the broad topic of Statistics.
Thus what exactly is Statistics?
Please go through the 2 videos posted below.

Introduction to Algebra Part 2

Dear 104s,

Please solve the following problem using both the Model method and the Algebraic method.



Now look at both your solutions, what are some of the similarities and differences between the 2 methods?

Introduction to Algebra Part 1

Dear 104s,

Please look through the presentation slides before we began our exploration of Algebra in the coming week (8 Mar to 12 Mar 2010).

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.

The Need of Numbers (15 January 2010)

As an individual, consider

1) Why is there a need of having numbers?

2) When did the first use of number, based on your imagination, occur?

Please post your comments by 16 January 2010.
