Scenario B. The NMC starts off with a clear statement on pupil morale. This is followed by a detailed statement on general strategies which are the essence of mathematical thinking. Finally, it deals with mathematical tactics. Within this scenario it is strongly emphasized that pupil morale is paramount, followed by mathematical strategies and then mathematical tactics (concepts, skills and facts) strictly in that decreasing or der of importance. In simplistic terms this is based on the obvious principle: forgetting a fact (such as 7x8 = 56) can be remedied in a few seconds, but bad work habits and poor attitudes are extremely difficult to correct and may, indeed, be irreversible.
