Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects). (E)K.NS.3Say the number names in standard order when counting objects, pairing each object with one and only one number name and each number name with one and only one object.

Count out the number of objects, given a number from 1 to 20. (E)K.NS.4Identify sets of 1 to 10 objects in patterned arrangements and tell how many without counting. (E)K.NS.5Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group (e.g., by using matching and counting strategies).K.NS.6Compare the values of two numbers from 1 to 20 presented as written numerals.K.NS.7Define and model a "ten" as a group of ten ones.
