Geometry the Fun Way: Congruence

Thursday, December 24th, 2009

How often do teachers try to teach mathematical concept using objects used in our day-to-day lives? Research has shown that children understand things better when they are taught using images and objects that they see and use. Though most educators and parents know this, not many really implement this to educate children.

Take for instance, congruence of triangles. I am use most teachers would use the following images to teach ‘congruence’ to children.

The problem with these images is that children might not take interest in understanding the concepts as they do not find ‘fun’ in these.  While these images are good for senior students, a beginner in geometry might fail to understand the meaning of ‘congruence’.

However, the same can be taught in an interesting fashion.

Online tutoring is a great way of teaching children using images and pictures. Modern tools like the whiteboard allow online tutors to import images and even change their alignment to teach a concept to children.  Online math tutors, in particular, can use images used in our day-to-day lives to teach mathematical concept to K-12 students in an interesting way.

Geometry in Real Life

Thursday, December 24th, 2009

In general, whenever we are stuck solving a problem or understanding a concept, we think to ourselves “This is sheer waste of time. Am I going to use this in real life?” I agree that for most subjects, only the core elements are used in real life and not the details. However, there is one aspect of mathematics that will come across in varied forms in real life. You guessed it right, I am talking about Geometry.

Let us talk about some of the practical aspects of geometry that we, often unknowingly, use in real life over and over again. Christmas has almost arrived. Most of us would be busy decorating our homes with Christmas trees and bells. But before buying a Christmas tree, don’t we first try to determine its size that would fit in our drawing room through the main door? In other words, we determine the width and height of the tree. And that’s geometry, isn’t it?

The same goes with an architect who is about to develop a construction plan for a new building. Cooking is no different. When we bake a cake in a microwave-safe bowl, we determine the quantity that would fit in the bowl.  There are hundreds of examples that demonstrate geometry into action in our day to day lives.

Geometry can be made fun. Online Tutoring organizations can conduct workshops on teaching geometry to children using day-to-day objects. Geometry is an essential part of online math tutoring. An online geometry tutor would not only help children understand the concepts given in their school books, but also learn to apply those concepts in real life without getting bored.
