26 Sept...Fraction, Multiplication and Geometry

Teaching Mathematics is all about formulas, steps, four operations knowledge...but today, I enjoyed the topic on fraction.  Dr. Yeap played a short nursery music video "Three Little Pigs" which I enjoyed alot.  After enjoying the sond, Dr. Yeap gave us a fraction problem to solve:

3 little pigs share 4 pizzas equally....how much should each little pig get?


 

 

 
 

These are my methods of solving this question...do you have other methods?

Polygon

Do you know what is a polygon?


A polygon is a plane shape with straight sides.

Is it a Polygon?

Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up).
Polygon
(straight sides)
Not a Polygon
(has a curve)
Not a Polygon
(open, not closed)
Polygon comes from Greek. Poly- means "many" and -gon means "angle".

I have learnt the way of finding area of a polygon using the formula....it is amazing indeed!
