随着儿童的进步，智力策略在减法的加法和计数方面的作用越来越重要。儿童通常以混凝土材料如计数器开始，直到他们发展信心的精神工作。数学意识和能力的发展，孩子们越来越挑剔的策略可以选择在手的问题最合适的策略。教育理论家，近年来一直试图确定影响儿童习得策略的因素。研究策略是一个重要的工具，在深入了解儿童组织和使用信息的方式。在早期学习中形成的策略形成的策略，将用于整个学校和超越的基础。研究人员刚刚开始发现，作为一个功能的工作记忆，上下文的影响，领域知识，流畅性和问题结构的个体差异发展战略.

As children progress, mental strategies take on an increasingly important role with adding on being used in respect of addition and counting back in respect of subtraction. Children normally begin with concrete materials such as counters until they develop the confidence to work mentally.Children come to school with a variety of strategies at their disposal. As mathematical awareness and competence develop, children become more discerning in respect of their strategies are able to choose the most appropriate strategy for the problem in hand.Educational theorists have, in recent years, been attempting to determine the factors that influence children’s acquisition of strategies. Research on strategies is an important tool in giving insight into the ways children organise and use information. Strategies formed in early learning form the basis for developing the strategies that will be used throughout school and beyond. Researchers are just beginning to find out how strategies develop as a function of individual differences in working memory, contextual influences, domain knowledge, fluency and problem structure
