Counting And Cardinality
Know number names and the count sequence
PK.MATH.1. [NY-PK.CC.1.] Counts to 20
Note: Emergent Multilingual Learners may demonstrate this Standard by counting in their home language(s).
PK.MATH.2. [NY-PK.CC.2.] Represents a number of objects (0-5), with a written numeral 0-5 (with 0 representing a count of no objects) Note: Students can select the corresponding number card and/or write the numeral.
Counts to tell the number of objects
PK.MATH.3. [NY-PK.CC.3.] Understands the relationship between numbers and quantities to 10, connects counting to cardinality
PK.MATH.3a. [NY-PK.CC.3a.] When counting objects, says 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. (1:1 correspondence)
PK. MATH.3b. [NY-PK.CC.3b.] Explores and develops the concept that the last number name said tells the number of objects counted, (cardinality). The number of objects is the same regardless of their arrangement or the order in which they were counted.
PK.MATH.4a. [NY-PK.CC.4a.] Answers counting questions using as many as 10 objects arranged in a line, a rectangular array, and a circle. Answers counting questions using as many as 5 objects in a scattered configuration (e.g., how many ____ are there?”)
Note: Non-verbal students may demonstrate this skill by using an answer card, objects, computer program, or their fingers.
PK.MATH.4b. [NY-PK.CC.4b] Given a number from 1-10, counts out that many objects
Compares numbers
PK.MATH.6. [NY-PK.CC.5.] Recognizes whether the number of objects in one group is more than, fewer than, or equal to (the same as) the number of objects in another group (e.g., using matching and counting strategies
Note: Include groups with up to five objects
PK.MATH.7. [NY-PK.CC.6.] Identifies first and last related to order or position
