Transcription

1 in 2011 Mathematics Frameworks Pre-Kindergarten Kindergarten Developing an understanding of whole numbers to 10, including concepts of one-to-one correspondence, counting, cardinality (the number of items in a set), and comparison. Representing, relating, and operating on whole numbers, initially with sets of objects. Describing shapes and space. Recognizing two-dimensional shapes, describing spatial relationships, and sorting and classifying objects by one or more attributes. Relatively: more learning time should be devoted to numbers than to other topics. Relatively: more learning time should be devoted to developing children s sense of number as quantity than to other mathematics topics. Comeau-Pittsfield 1
