### Revision: Factorisation

You are given a set of Revision paper, "Algebra - Factorisation - Summary of 4 methods"

Here are the 4 sets of video clips for your reference:
• p1: Summary
• p2-p3: Practice
• p4-p5: Error Analysis
• p6: On your own - more practice

### Linear Graphs: Knowing the Graph Paper and the Basics

In this playlist, there are 4 video clips that show

• How to read the 'squares' of the graph paper
• How to mark the intervals on the axes according to the scale given.

### Drawing Linear Graphs

For clarity in illustration, ink is used in this 'demonstration'.
You should use a sharp pencil, and ruler to plot your graph. Always get ready an eraser to clean off any irrelevant markings.

Step 1: How do we decide where to place the axes?
• Do you "know" the graph paper?
• What would you make reference to?

Step 2: Scale matters!
• The numbers on the axes must be clearly marked.
• The scale should be written on the top right corner of the graph paper.

Step 3: Let's start plotting!

• Mark the points clearly with "X"
• Join the points with a straight line (use a long ruler!)
• The line should be drawn within the given domain

### Catch the Cockroaches with...

In this activity, you will learn how to 'programme' your 'weapon' to kill cockroaches that run across the room in straight lines only! Yes, these are highly intelligent cockroaches that only run in straight paths!

Before starting the game, it is important for you to read the instructions first.

### Maths lessons on T2W3

Dear S1-02

As spoken last week, there will be some changes to the days (and time) of the maths lessons this week as I am not in school on Wednesday and Thursday.

While I'm not around, you can still send me emails for work that you need to clarify.

### Saving the Planet through Solving Simple Linear Equations

Objective of playing the game:
Improve mastery of skills to solve linear equations, hence familiarity. With mastery and familiarity, one should be able to improve on the duration needed to solve linear equations questions.
This is to address to one of the areas for improvements highlighted in Level Test 1.

### 6 AM Quiz: Algebraic Art!

In Algebra, a relationship between 2 variables can be described by an equation; and we used Grapher to help us 'graph' out the relationships.

Here's a website that you will find pictures created with lines of equations with 2 variables.
https://www.desmos.com
Try examining some of these pictures to see how lines, when put together, can generate amazing pictures.
Are you able to come up with one?

### Introduction to Inequalities

We are going to formally start the topic, Inequality next week.

Attempt
• p98: Example 1 (a) to (f)
• p98: Exercise 1: Tier A Q1 (a) to (f), Q2 (a) & (b)

As a prelude, you may also attempt the following Games.
You may use a calculator. The objective is to help you process simple inequalities

(1) The Inequality Game

(2) SpeedMath - Inequalities

(3) Shooting Inequalities

### [Update 1] Homework: Let's Play with Equations!

Up to 3 April 2014, 7 am:

This is similar to one of the questions we discussed in class...

Has the following approach crossed your mind?

### Save the Earth with Equations

A group of alien robots is invading the earth!
To programme the weapon such that it could destroy these invaders, you need to solve linear equations!

You are selected to be part of the special task force that has been set up to handle these alien robots.
Up to day, below are the top performers of the team.

It's your turn now to carry out the mission.
Your points scores will be recorded
