Assessment in Term 4 2013
Dear SSTudents,
1. Performance Task 2 (in lieu of Elementary Mathematics)
As mentioned earlier the deadline of the PT2 is 16 September 2013 @ 2359. To date many students have submitted their products with high quality questions and 'proof's. Effective use of ICT tools (google, Blog, Geogebra, Keynote, Powerpoint, Pretzi etc) have further enhanced the final product.
2. Paper 3 (in lieu of Additional Mathematics)
The assessment information will be as follows:
Date: 23 September 2013 (Monday)
(Please be punctual and ensure you have a heavier meal in the morning)
Time: 3.00 pm to 4.00 pm
Venue: Auditorium
Note that you are required to sit according to your classes and index numbers. The teachers will supervise you on this.
Logistic:
TI84 Graphic Calculator (or other approved GC model)
(no other calculator will be allowed)
Stationery - pen and ruler
3. Information on EOY
Please refer to your class math blog or google site earlier entries on this.
All the best - you can do it because we have faith in you but do you!

5 THINGS WE NEED TO KNOW WHEN DRAWING A GRAPH :D
1) SCALE
Example :
Horizontal axis
8cm: 1 unit
Vertical axis :
2cm to 1 unit
*sometime the scale is given in the question*
_______________________________________________
2) Accuracy
-> How accurate the graph is eg.
Accuracy =1/2 square
______________________________________________
3) FOR LINEAR LAW
->> Vertical intercept must be shown in the graph______________________________________________
4) Size of graph
The graph should fill up 2/3 of the graph paper
~ which means we have to choose the scale properly.
> For accuracy purpose
>> Less error
____________________________________________
5) Table of values must be shown
example
