“算用结合”是现代数学作为整体的一种反映,是学生数学学习的一种方式,是教师数学教学的一种策略。“算用结合”是一对相互依存的共同体,不能简单地将它们拆开。通过“算用结合”的教学,更好地促进学生和谐发展。一般来说,“算用结合”中的“算”指口算、笔算、估算、四则运算等。它不但指获取各种计算方式的过程,还要充分体现计算的基础性和工具性。“算用结合”中的“用”指的是应用、解决问题。“用”已经成为数学四大领
“Combination of calculation and calculation ” is a reflection of modern mathematics as a whole, a way for students to learn mathematics, and a strategy for teachers’ mathematics teaching. “Calculated with ” is a pair of interdependent community, can not be simply split them. Through “combination of calculation and teaching”, we can better promote the harmonious development of students. In general, “arithmetic combination ” in the “arithmetic ” refers to the mouth count, pen calculation, estimation, arithmetic and so on. It not only refers to the process of obtaining various calculation methods, but also fully embodies the calculation of the basic and instrumental. “Count with combination ” in the “use” refers to the application to solve the problem. “Use ” has become the four major math
