K.CC.A.2 - Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
K.CC.B.4a - Understand the relationship between numbers and quantities: connect counting to cardinality. 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.
K.CC.B.4b - Understand the relationship between numbers and quantities: connect counting to cardinality. Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.
K.CC.C.6 - Identify 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. (Include groups with up to ten objects.)
K.CC.A.3 - Write numbers from 0 to 20. Represent a number of objects with a
written numeral 0-20 (with 0 representing a count of no objects).
K.CC.B.5 - Count to answer “how many?” questions about as many as 20 things
arranged in a line, a rectangular array, or a circle, or as many as 10
things in a scattered configuration; given a number from 1–20, count
out that many objects.
K.CC.B.4 - Understand the relationship between numbers and quantities: connect counting to cardinality.
