STUDY NOTES (p12): Application of Special Products
Posting them here for your reference.
POSTED on 13 MAY - after class discussion
Class Practice (III) Our discussion on 24 APRIL
During the lesson, we looked at how (a) and (b) can be simplified using single fraction.
We learnt that while the approach could be different, both methods give the same answers (though they look different). We can also show how one answer is equivalent to the other.
For (c), the approach is similar to the following arithmetic example. When it is a product, we can expand the three factors in any order.
- 2 x 3 x 5 = (2 x 3) x 5 OR 2 x (3 x 5) OR (2 x 5) x 3
[Wrapping up] Mensuration - Word Problems (Pyramid, Sphere, Composite figures)
We discussed the following questions during lessons.
Below are the suggested solution, showing how the working should be presented:
Volume of Solids (non-Prism)
VOLUME of CONE
VOLUME of CYLINDER
VOLUME of SPHERE
RELATIONSHIP OF VOLUME of Cone, Sphere and Cube (think... what do they have in common?)
VOLUME of CYLINDER
VOLUME of SPHERE
RELATIONSHIP OF VOLUME of Cone, Sphere and Cube (think... what do they have in common?)
[TRAT activity] Mensuration - Perimeter and Area of Plane Figures
As mentioned in class this morning, the group will assign ONE Question to ONE MEMBER to post your worked solution in the Padlet.
