With a 5 / 6 Small class I worked on optical illusions. In an introduction to various optical illusions, we will contact the various elements that are contained in it apart. Then it went to the notebook and the children started the program StarOffice Draw. In this drawing program, they had to first lines, Circles, rectangles and squares to paper. I have presented them nothing, but they have to find out through discovery learning itself. With these elements, they could now do the first drawing attempts.
In the second double lesson we took the thread to the optical illusions through the examples again. The children now had to first divide the sheet in StarOffice Draw a line. Then they were allowed to represent each half of an element of optical illusions, such as a circle and rays. Once they were finished with their work, we printed the results on a slide. The film they have cut in half, this one above the other states that there was an optical illusion. This did not work at all. Finally, we have hung the pictures to the window and stimulate a discussion of why it offers to some optical illusions is why other just does not.
