数形结合思想是一种重要的数学思想。在教学中渗透数形结合的思想,可把抽象的数学概念直观化,帮助学生形成概念;可使计算中的算式形象化,帮助学生在理解算理的基础上掌握算法;可将复杂问题简单化,在解决问题的过程中,提高学生的思维能力和数学素养。“数形结合”既有助于发展学生的数感,又能促进学生数学思维的发展。适时的渗透数形结合的思想,可达到事半功倍的效果。
The combination of number and shape is an important mathematical thought. Permeating the combination of number and shape in teaching can visualize abstract mathematical concepts and help students to form concepts. Visualization of computational formulas can help students to master algorithms based on understanding arithmetic. Complex problems can be easily solved In the process of solving problems, improve students’ thinking ability and mathematical quality. “Combination of numbers and forms ” not only help to develop the sense of number of students, but also promote the development of students’ mathematical thinking. Timely penetration of the combination of number of ideas, can achieve a multiplier effect.
