智障儿童一般指大脑受损而智力发展障碍的儿童,其智力水平比同龄儿童低,且发展速度慢。他们中的大多数人存在语言不同程度的缺失,并且大部分不善言谈。为了使他们今后能融入社会,在课堂教学中对智障儿童进行语言训练就显得十分重要。小学数学教材中的 Children with mental retardation generally refer to children with impaired brain development and mental retardation who have a lower level of intelligence than children of the same age and have a slow pace of development. Most of them have varying degrees of language loss, and most are poorly conversed. In order to integrate them into society in the future, it is very important to train children with intellectual disabilities in classroom teaching. Primary school mathematics textbooks
