Meaningful Equations: Some formulae (in advance)

Have you ever wonder how some of these formulae are derived or how to verify some of them?

1. The Pythagoras Theorem

There are 2 clips that's shared during the lesson relating to the Pythagoras' Theorem:

2. Area of Trapezium

Do you know, we can derive the formula for the area of a Trapezium using area of triangle and factorisation?

 

3. Surface area of a sphere

Do you know that the Surface Area of a Sphere is related to the area of circles?

[Group Discussion] Factorisation Pyramid Challenge

This was carried out during lesson in the week before National Day (approx 30min).

The challenge is to recognise "characteristics" of the given expression and apply the appropriate factorisation method(s) to factorise the expression completely.

On the whole: 

• Group A 3 points
• Group B 10 points
• Group C 13 points 👏 🏆
• Group D 11 points 
• Group E 12 points 
• Group F 12 points 
• Group G 9 points
• Group H 13 points 👏 🏆
