Dr. Yeap posed a question: How do you know a triangle is 180 degrees?
Despite the various types of triangle; scalene, isosceles, equilateral, it is 180 degrees.
-Use of protractor
Cut the three edges of a triangle and put it on a straight line. if it is on a straight line, it is 180 degrees.
Thus,visualisation and meta cognition skills enables easier problem skills.
Piaget stated that, “Children construct their own knowledge in
response to their experiences.”
Thus when children are given concrete materials, they are able to visualise their experience in getting to know why a triangle is 180 degrees than to learn how to get the answer.
Dr. Yeap mentioned that “Mathematics is an excellent vehicle for the development and improvement of a person’s intellectual competence..”
