NC.K.CC.3 Write numbers from 0 to20. Represent a number of objects with a written numeral 0-20, with 0 representing a count of no objects
NC.K.CC.4 Understand the relationship between numbers and quantities. ● When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object (one-to-one correspondence). ● Recognize that the last number name tells the number of objects counted regardless of their arrangement (cardinality). ● State the number of objects in a group, of up to 5 objects, without counting the objects (perceptual subitizing).
NC.K.CC.5 Count to answer “How many?” in the following situations:
● Given 20 objects arranged in a line, a rectangular array, and a circle, identify how many. ● Given 10 objects in a scattered arrangement, identify how many. |
