are letters, although substituting shapes is a great idea. I think it is that
they do not understand the concepts. A simple problem to us, such as x+3=5,
stumps students. Why? One of the issues may definatley be that anything other
than a number does not make sense. Formulas are abstract if the students do not
understand what the variables mean, what they represent, and how they are
useful.
