                   1.  Take 2 Origami sheets and divide them into halves in as many
                      different ways as you can. (Teacher can assist the students.)
                   2.  Now, take a rectangular sheet of paper and divide it into 3 equal
                      parts and 4 equal parts.

                We represent a fraction in the following way:

                                                     Number of parts shaded or coloured
                                      Fraction =
                                                       Total number of equal parts made

                Look at the shaded parts of the following figures. Write the fraction for the shaded
                parts.
