Final push!

hi everyone,

been a good 3 months with everyone in the group here. Frankly, its 'scaringly' fast, seeing how fast time flew by.

Now its the final lap for Yr 3, push on!

remember, you are only 14 or 15 once. YOLO.
Don't waste any single bit of your precious youth.

I'm sure all of you will surely achieve,  if u persevere and fight hard enough for what you wish for and earnestly want to own.

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.

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!
