We covered the topic of Geometry during Math class today. The activities that we carried out brought a fresh perspective to me. I have never thought of looking at Mathematical concepts such as angles and shapes this way. Most of us know that all angles in a triangle add up to 180 degrees. Yet, how many times have we ever questioned the origin and derivation of the rule? Our education has been focused on rote learning for so many years. Now, it is time to really think about and question the rationale and origins and principles. The photo above shows how to derive the rule that all angles in a triangle add up to 180 degrees. Are you able to see it?

i saw it... it was the way i would have taught a kid if i were teaching. i remember seeing that in an american guidebook but very few teachers in singapore have actually done that to help students visualize. it's amazing how asian kids are able to excel in math better than the caucasians
