Assuming the inadequacy of current teaching models in relationship to the concept of limit, it was deemed necessary to design a realistic model of teaching that is compatible with the national curriculum. To this end, initially the characteristics of such a model were identified and then a preliminary draft of the model as well as daily lesson plans were constructed. This draft was then taken to a workshop with experienced teachers who edited and improved the model in 5 sessions leading to the final edition. Through a questionnaire and cooperation of informed individuals, the validity of the final edition was assessed to be adequate.
