Our teacher, Mr Sim, would use various tools such as geogebra and ted-ed videos to teach and introduce to the class new concepts.

Questions/problems for parents to try out

Question 1:

Question 2:

Question 3:

solutions/answers

(please note that you MUST have presented and labelled your working as realistically in class you would be penalised.)(there are also many other methods than the ones presented)

This was made while we learnt about negative and positive numbers, Mr. Sim would draw a number line for us to help us visualise how negative numbers worked.

This was made when Mr Sim taught us how to find the surface area of solids by unfolding them into their nets, this gave us a clearer vision and a better understanding of the concept(s).

Mr.Sim taught us how to use the formula [(n-2)X180º] to find the sum of all interior angles in the Polygon. He taught us how to name Polygons like hexagon.

This page is about Mr. Sim teaching us the formulae for triangles, parallelograms, and trapeziums, to find the area of a trapezium, we use the formula, 0.5xh(a+_b).
