Linear Equations [HW1] (Part 2) Articulating the solving of Equations
Refer to the Google Classroom for the complete set of instructions for HW1.
(A) Clarity in presentation of working (max: 2m)
[0] Does not solve equation systematically (e.g. change to arithmetic calculation halfway)
[1] Presentation issues (e.g. 2 "=" on the same line)
[2] Clear and systematic presentation
(B) Answer (max: 1m)
[0] Incorrect answer or when non-exact answer is presented
[1] Correct answer - found through equation solving
(C) Articulation of Concepts (max: 2m)
[0] Balancing concepts not articulated at all
[1] Some appropriate terms are used to describe the balancing concept OR Some appropriate algebraic manipulation terms like "single fraction", "simplify", "expand" are used
[2] Most appropriate terms are used to explain concepts and manipulation
(D) The Product (max: 1m)
[0] Video is beyond 2 minutes. Quality is poor (e.g. voice not audible, what's written is not clearly capture)
[1] Video is kept to 2 minutes (max) with audible voice
This is Part (2) of HW1
Pay attention to he following when you articulate the solving of the equation:

Algebra (Method 2) Factorisation by GROUPING
We attempted Study Notes (p19) during lesson.
Here's the set of answers for reference.
We'll further the discussion in the next lesson.
