Prekindergarten Math (New York Next Generation)

Counting and Cardinality

• Know number names and the count sequence
• NY-PK.CC.1 Count aloud to 20.
• NY-PK.CC.2 Write a numeral from 0 to 5 matching a set of objects, with 0 meaning none.
• Count to tell the number of objects
• NY-PK.CC.3a Pair each counted object with one and only one number name, and each name with one object.
• NY-PK.CC.3b Explore that the last number said gives the total, regardless of arrangement or counting order.
• NY-PK.CC.4a Answer "how many" for up to 10 objects in a line, array, or circle; up to 5 if scattered.
• NY-PK.CC.4b Given a number from 1 to 10, count out that many objects.
• Compare numbers
• NY-PK.CC.5 Tell whether one group has more, fewer, or the same number as another, with groups up to five.
• NY-PK.CC.6 Identify "first" and "last" related to order or position.

Operations and Algebraic Thinking

• Understand addition as adding to and understand subtraction as taking from
• NY-PK.OA.1 Explore addition and subtraction using objects, fingers, and real-world situations.
• Understand simple patterns
• NY-PK.OA.2 Duplicate and extend simple patterns using concrete objects.

Measurement and Data

• Describe and compare measurable attributes
• NY-PK.MD.1 Identify measurable attributes like length or weight and describe them with appropriate vocabulary.
• Sort objects and count the number of objects in each category
• NY-PK.MD.2 Sort objects and shapes into categories and count each, with category counts of 10 or fewer.

Geometry

• Identify and describe shapes (squares, circles, triangles, and rectangles)
• NY-PK.G.1 Describe objects using shape names and relative positions such as above, below, and next to.
• NY-PK.G.2 Name shapes regardless of their size.
• Explore and create two- and three-dimensional objects
• NY-PK.G.3 Explore 2D and 3D objects, informally describing their similarities, differences, and attributes.
• NY-PK.G.4 Create and build shapes from components, such as sticks and clay balls.
