Teaching geometry with paperfolding (Argentina- 1958)

Post by Laura Rozenberg » Mon Jan 06, 2014 2:21 pm

Here are some examples of how geometry and math were taught in elementary school in Argentina. The years illustrated are 1958 (with my sister's notebook) and 1966 (my notebook).

In 1958 my sister was 8 years-old. She had to cut strips of paper and divide them in fractions (picture 1).

Following are two pictures of my own notebook, 1966 (I was 9 years-old), showing how we learned properties of the square and other geometrical bodies.

I have more examples but this entry only allows up to three pictures.

There was a previous discussion about the loss of the use of paperfolding in elementary schools after the military coup but I'm not sure there was a sharp cut at least for a while. In fact, in 1966 we were already under a military government and the notebook shows we continued using paperfolding. I can't think of any logical reason why militaries despite we know they had all kind of crazy ideas would take on paperfolding anyway.

Anyway, I just wanted to illustrate how Argentine curricula heavily leaned on paperfolding to teach geometry and math (specially fractions). It doesn't seem to be a so modern discovery!
