在小学数学课堂教学中充分利用自制教具,变抽象为直观,变被动为主动,既能提高学生的学习兴趣,发挥学生的主体作用,又能培养学生的创新能力,收到事半功倍的效果。 Making full use of self-made teaching aids in primary school mathematics classrooms can turn abstract into intuitive and passive. It not only improves students ’interest in learning, plays the main role of students, but also fosters students’ innovative ability with a multiplier effect.
