数形结合思想就是把数量关系和空间形式结合起来去分析问题、解决问题。数形结合是小学高年级学生解决数学问题的有效方法,数形结合思想对学生数学学习尤为重要。“以形助数”让学生能够更直观地理解数学知识;“借数解形”帮助学生建立数感;“数形结合”借助表象开阔学生的思维。数形结合是相互联系,相互作用不可分割的整体。
The idea of combining numbers with numbers is to combine quantitative and spatial forms to analyze and solve problems. The combination of number and shape is an effective way to solve the mathematics problem of the senior students in elementary school. The combination of the number and shape is especially important to students’ mathematics learning. “To form aids ” to enable students to more intuitive understanding of mathematical knowledge; “Borrowing solution ” to help students build sense of number; “combination of number and form ” with the image of open-minded students thinking. The combination of several forms is an integral whole that is interrelated and interacts with each other.
