**Task 1**

**collaborative work**

using

*TI-Nspire*tobuild your foundation on the key concept using examples presented in a collaborative environment.

========================================================

**Task 2**

**Pair work**

based on the activity in task 1, reflect on the processes involved and write it down on your worksheet 5.

Identify at

*least 2 points*for consideration for 'Change of Subject'.You may discuss with a partner in class.

Submit this at the end of the lesson.

reference:

Worksheet 5, ACE learning.

========================================================

**Task 3**

**individual work**

**Extension of understanding on Change of Subject**

Identify a formula in other subject areas (other than Mathematics)

- define which subject area the formula is applied and what the formula is about

- define all the variables used

- identify a variable (other than the one presented) to make a subject.

(ensure that this is possible)
