M3. Cardinality

Responds to requests to give a small quantity of items (e.g., one, two) with some mistakes.

Gives one to two and only one to two items upon request.

Identifies a correct quantity (e.g., three or four objects) with a number word (e.g., "three" or "four") up to four items.

Gives the correct number of items consistently, when asked, up to four.

Identifies a correct quantity (between four and 10 items) with a number word (e.g., "four" or "six").

Gives the correct number of items consistently when asked, for between four and 10 items.

Identifies that the final number word used when counting out an item set represents the exact number of items in the set.

Understands the number of objects in a set does not change and is the same regardless of the arrangement or order in which they were counted (e.g., when there are five different animals in a group, the quantity is the same whether they are in a circle or a line).

Recognize that a number can be used to represent how many objects are in a set or to represent the position of an object in a sequence. When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number with one and only one object. Understand that the last number said tells the number of objects counted. Understand that each successive number refers to a quantity that is one more. Name the position of an object in a sequence (ordinal count). (MP1, MP6)
