新课程标准指出:小学数学教学要发展学生的符号意识,让学生能够理解并且应用符号表示数与数之间的关系变量、利用符号进行数的计算,还要熟练掌握如何对符号进行推导、如何演算,充分了解符号含义并加以利用,从而达到解决问题的目的。因此,在小学数学课堂教学当中,要建立学生的符号意识,理解并学会运用符号,只有这样,才能强化数学概念,提高解决数学问题与数学问题之外的能力。一、拓展教学资源——奠定符号语言基础新课程标准要求我们教学内容需结合实际生活,不脱离日常生活,
The new curriculum standard points out that primary mathematics teaching should develop students’ sense of symbols, enable students to understand and apply symbolic relationships between numbers and numbers, use symbols to count numbers, master symbols and how to deduce them Calculus, fully understand the meaning of symbols and to use, so as to achieve the purpose of solving the problem. Therefore, in elementary mathematics classroom teaching, it is necessary to establish the student’s symbolic awareness, to understand and learn to use symbols, the only way to strengthen the mathematical concepts, improve the ability to solve mathematical problems and mathematical problems. First, to expand teaching resources - to lay the foundation of a symbolic language The new curriculum standards require our teaching content should be combined with the actual life, not out of daily life,
