Maths Alternative Assessment 2: Preparation

Today's classroom discussion & preparation:

Term 2 Group Performance

The Best Performing Group in Term 2 goes to... Group 4

Review of Class Activity: Plotting of Graph

(a) What is "wrong" with this graph?

Given scale:
x axis          2 cm : 1 unit
y axis          2 cm : 2 units

(b) What is "wrong" with this graph?

Given scale:
x axis          2 cm : 1 unit
y axis          2 cm : 2 units

Summary: 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

Dear S1-01

To prepare yourself for the topic that we'll be doing this week, do take some time to attempt the activities that are posted in the Maths GoogleSite > 02 Introduction to Graphs of Linear Equations

There are several activities, to prioritise, do attempt the following first.

Activity 1: What makes up the linear equations?

Before you begin with the game, click at INSTRUCTIONS (at the bottom of the page) to learn what each of the following mean:
(i) y-intercept - usually denoted by "c"
(ii) rise/ run, a formula that is used to calculate the slope (gradient) - usually denoted by "m"
(iii) a straight line path can be described with the linear equation, Y = mX + c
You need to understand the above in order to accomplish the mission
