You can use a length model, for example a length of paper.  Divide it
into 5 equal parts by measuring (or folding if you can). Colour in 3
out of the five parts. Then, using the same length of paper, fold it
again so that you have 10 equal parts.  Let the student see that the
same 3 out of 5 parts, when now folded into 10 parts is equal to 6 out
of 10.  Therefore 3/5 = 6/10.  Do this with different types of models
so that the students can gain the concept.  Let student try to figure
out what is happening with the numerator and the denominator.  He
would see that both are being multiplied by the same number for an
equivalent fraction to resul.
