Somehow, despite the availability of re sources, some teachers still find it a challenge to include mathematical modelling as part of their classroom learning activities. Moreover, as noted by Smith (1996), even if these were carried out, they may be done consciously and systematically. Mathematical modelling is considered cognitively demanding, both for the student and the teacher (Blum and Borromeo Ferri, 2009). It is therefore important that one approaches this aspect of mathematics teaching with much care and planning. The teacher may have to learn alongside the student, and a first step would be to "become conversant with the tools of the trade" (Warwick,2007,pp.34).
