本文将考虑“地方价值”的作用;一个支持十进制数字系统的概念，它是成功解决问题的基础。它将特别考虑导致加法的教学的步骤，它从关键阶段1开始，并将检验不熟悉的位置值如何影响数学技能，如在关键阶段2中添加的列。专业和政府指导教授这些技能将被检查和比较在课堂上发现的经验，并与实际的解决方案，可以用来帮助避免这种误解。印度-阿拉伯语系统由数字0-9组成，它可以创造任何数字，汤普森提醒我们，“人类花了很长时间才发明了这个重要的概念”，强调一些儿童可能对这个概念有困难。这一声明表明，需要广泛的教学方法来支持这一主题，以支持对十进制数字系统的上下文学习和理解;一个数字中的每一个数字代表了10的增加或下降的幂。在最合适的年龄，对孩子的位置价值有不同的看法。Shuard建议应该在小学教早期,而汤普森认为,如果过早被教导位值概念,它可能会导致混乱(尽管这些对比视图和符合国家课程,孩子从关键阶段1位值的概念包括:数字的值,使用0作为一个占位符,秩序和舍入的号码。

This essay will consider the role of 'place value'; a concept underpinning the decimal number system which is fundamental for successful problem solving. It will specifically consider the steps leading to the teaching of addition, which begin in Key Stage 1, and will examine how unfamiliarity of positional value may affect mathematical skills such as column addition during key stage 2. Professional and Government guidance on teaching these skills will be examined and compared to experiences found in the classroom, alongside practical solutions which may be used to help avoid such misunderstandings.The Hindu-Arabic system comprises of the digits 0-9 to create any number and Thompson reminds us that " it took humankind such a long time to invent this important idea", emphasising that some children are likely to have difficulties with this concept. This statement suggests that a wide pedagogical approach to this topic is needed to support contextual learning and understanding of a decimal numeral system; the idea that each digit within a number represents either increasing or decreasing powers of ten.There are contrasting views concerning the most appropriate age to introduce positional value to children. Shuard advised that it should be taught early in primary school, whilst Thompson believed that if place value concepts were taught too early, it may cause confusion (Despite these contrasting views and in line with the National Curriculum, children are introduced to the notion of place value from Key Stage 1 to include: the value of digits, the use of zero as a place holder, order and rounding of number.
