生物学研究证明:人的大脑皮层有特定的区域,同人的有关部位相联系,其中与人的双手有联系的特定区域占人整个大脑皮层的三分之一,智慧就在孩子们的手上,孩子们只有亲自参加活动,在操作活动中不断积累感性材料才能促进孩子们观察、实验、猜测、验证及推理概括的能力。因此,课堂上教师要给孩子们充足的时间和空间,让他们参加数学教学实验活动 Biological studies have shown that: the human cerebral cortex has a specific area, associated with the relevant parts of the human contact with the hands of a particular area that accounts for one-third of the entire cerebral cortex, wisdom in the hands of children , Children's ability to observe, experiment, guess, validate, and reasonably generalize only when they participate in the activity themselves and accumulate perceptual material in their activities. Therefore, teachers in the classroom to give children enough time and space for them to participate in mathematics teaching experiment activities
