Common Core Math: Counting & Cardinality

The Counting and Cardinality domain is covered entirely in kindergarten, where students learn number names up to one hundred and use them to count the numbers of objects in groups. Students develop an understanding of counting as pairing the counting numbers with the objects being counted. Students practice counting groups of up to 20 objects, reporting their results by writing numerals and comparing groups based on their numbers of objects.
