The Van hiele theory on the development of geometric thoughts is very helpful in structuring and teaching geometry. Five levels are identified, in the textbook, these levels are called level 0-4. (Note that in some other sources they are called levels 1-5. Give one example of how a learner on level 1 will define a rectangle. Give one example of how a learner on level 2 will define a rectangle. Discuss its meaning in the context of the classification of quadrilaterals as a lea1 on level 2 would do it. Reflect on how your knowledge of the thought levels of van Hiele will influence your own teaching of geometry.
