美国一家儿童博物馆的铭牌上刻着“听见的容易忘记,看见的容易记得,亲身做过的才真正理解。”在小学数学教学中,实践活动是儿童发展成长的重要途径,也是由动作直觉思维、形象直观思维逐步过渡到抽象逻辑思维的重要途径。形象性教学能把学生推到主体地位。眼、耳、口、手、脑多种器官同时活动,有利于调动学生的积极性和主动性,有助于培养他们的能力,发展他们的智力,使学生初步学会运用所学知识和方法解决一些简单的实际问题。
“A child’s museum in the United States is engraved on the nameplate,” “It’s easy to forget to hear, and easy to remember. It’s a real comprehension of what you do.” In elementary mathematics teaching, practical activities are an important way for children to grow and develop. Intuitive thinking, the visual image of the gradual transition to an important way of abstract logical thinking. Image teaching can push students to the dominant position. Eyes, ears, mouth, hand, brain, multiple organs at the same time activities, is conducive to mobilize the enthusiasm and initiative of students, help to develop their ability to develop their intelligence, so that students initially learn to use the knowledge and methods to solve some Simple practical problem.
