when you get to explore with cutting a shape to form a new particular shape of the same area. That was exactly the experience I went through and was totally awed by the experiential learning.
Once again we were subtly challenged to give many different ways of forming a rectangle of a similar area from the original trapezium given. The surprise came when we google the definition of a rectangle that mentioned, "A rectangle is any quadrilateral with 4 right angles." With reference to that, my coursemates and I learnt that a SQUARE is a RECTANGLE. Therefore, it is best to prevent giving shapes like squares and rectangles on paper activities for children to identify any one of the two shapes mentioned.
It took Dr Yeap a few attempts to convince the statement though until we succumbed to the fact and took a mind shift to accept what the norm had taught us. It will be useful to read the van Hiele levels of geometric thoughts on page 403 of the text to gain more insights.
