# Counting and Cardinality

Videos and songs to help Kindergarten kids understand the relationship between numbers and quantities that is connect counting to cardinality.

A. 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.

B. 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.

C. Understand that each successive number name refers to a quantity that is one larger.

Common Core Standards: K.CC.4

### Suggested Learning Target

• I can count objects in a group (each object is counted only once) regardless of arrangement and order.
• I can say "how many" are in a group after counting all the objects.
• If I already know how many are in a group, I can say how many there are (without recounting the whole group) when one more object is added to the group.
• I can explain my counting strategy.
• I know that when counting a set, the last number represents the total number of the objects in the set.
• I can apply a one-to-one correspondence when counting
• I know that the quantity of a set does not change, no matter how the objects of the set are displayed.
• I can immediately recognize a quantity when counting objects
• I know that when one more is added to a number set, this new number includes all the previous objects in the set, plus the new one. (e.g., 6+1=7)

## Counting Objects

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.

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.

Understand that each successive number name refers to a quantity that is one larger.
Counting 1-20.
Counting Objects
Pair a number with an object, the last number named equals the number of objects, and the next number in a sequence is one more than the number before it.

K.CC.4
The Common Core State Standards (CCSS) videos are designed to support states, schools, and teachers in the implementation of the CCSS. Each video is an audiovisual resource that focuses on one or more specific standards and usually includes examples/illustrations geared to enhancing understanding. The intent of each content-focused video is to clarify the meaning of the individual standard rather than to be a guide on how to teach each standard although the examples can be adapted for instructional use.
