deeply‚ I thought I would find ways to challenge these misconceptions. Key Concepts and Misconceptions of Area When defining area‚ Koshy et al (2000) discuss that it is a two dimensional concept and relies on comparison with a square due to measures of area being in centimetres squared (cm2) or metres squared (m2). Due to the nature of these measurements‚ it is easy to see why children misconstrue these concepts. The National Numeracy Strategy requires that teachers ’identify mistakes‚ using

Diseconomies of scale A more precise definition is that long run average costs per unit rises with an increase in output.This can b shown in the diagram below: [pic] The rising part of the Long Run Average curve illustrates the effect of diseconomies of scale. Beyond Q1 (ideal firm size)‚ additional production will increase per unit costs. Diseconomies of scale are rarer than economies of scale and they are often offset by economies of scale that exist in the same business. This can make
