### Update on Assessments (i) PT (ii) Paper 3 (iii) EOY

**(1) Performance Task 2**

This constitutes the Elementary Mathematics component of Assessment.

The performance task focuses on the topic of Geometrical Proof - Circle Properties. (please refer to Blog entry on Mathematics Performance Task 2)

Deadline for submission is

**Term 4 Week 1 (first lesson)**

**(2) Paper 3**

This constitutes the Additional Mathematics component of Assessment.

This will be conducted in

**Term 4**.
Students are expected to familiarise themselves with GC-TI84+.

(please refer to your Math teacher on information on use of GC-TI84+)

**(3) End-of-Year Examination: Mathematics**

Information pertaining to the Maths exam has been communicated to the students in the GoogleSite (as well as the Maths blog).

### Assessment in Term 4

Dear SSTudents,

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.

The assessment information will be as follows:

Date:

(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

Please refer to your class math blog or google site earlier entries on this.
