In the preschool stage,the influence of different types of toys on children's cognitive development should be focused on,and the characteristics and roles of con-structive,artistic,scientific and numerical toys should be emphatically analyzed.These different types of toys have their own focuses,which jointly promote the comprehen-sive development of children's cognitive ability.Based on the above analysis,this paper puts forward some sugges-tions on the scientific selection and use of toys in preschool education,emphasizing that appropriate toy combinations should be selected according to children's age character-istics and individual differences,and the balance between adult guidance and children's independent exploration should be paid attention to in the use process,so as to sup-port children's comprehensive cognitive development.
