Making Numbers

Kindergarten

Alabama Course of Study Standards: 10

Decompose numbers less than or equal to 10 into pairs of smaller numbers in more than one way, by using concrete objects or drawings, and record each decomposition by a drawing or equation.
Example: 5 = 2 + 3 and 5 = 4 + 1

Arkansas Academic Standards: K.OA.3

Use objects or drawings to decompose (break apart) numbers less than or equal to 10 into pairs in more than one way, and record each decomposition (part) by a drawing or an equation (e.g., 5 = 2 + 3 and 5 = 4 + 1)

Note: Students should see equations and be encouraged to recognize that the two parts make the whole. However, writing equations is not required.

Arizona - K-12 Academic Standards: K.OA.3

Decompose numbers less than or equal to 10 into pairs in more than one way (e.g., using fingers, objects, symbols, tally marks, drawings, expressions).

Common Core State Standards: K.OA.3

Ohio's Learning Standards: K.OA.3

Decompose numbers and record compositions for numbers less than or equal to 10 into pairs in more than one way by using objects and, when appropriate, drawings or equations.

North Carolina - Standard Course of Study: K.OA.3

Decompose numbers less than or equal to 10 into pairs in more than one way using objects or drawings, and record each decomposition by a drawing or expression.

New York State Next Generation Learning Standards: K.OA.3

Decompose numbers less than or equal to 10 into pairs in more than one way.
Record each decomposition by a drawing or equation.
e.g., using objects or drawings.

Tennessee Academic Standards: K.OA.3

Decompose numbers less than or equal to 10 into addend pairs in more than one way (e.g., 5 = 2 + 3 and 5 = 4 + 1) by using objects or drawings. Record each decomposition using a drawing or writing an equation.

Wisconsin Academic Standards: K.OA.3

Compose and decompose quantities within 10
  1. Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition with drawings or numbers.
  2. Quickly name the quantity of objects briefly shown in structured arrangements anchored to 5 (e.g., fingers, ten frames, math rack/rekenrek) with totals up to 10 without counting by recognizing the arrangement or seeing the quantity in subgroups that are combined (conceptual subitizing).

Texas Essential Knowledge and Skills (TEKS): K.2.i

compose and decompose numbers up to 10 with objects and pictures.

Pennsylvania Core Standards: CC.2.K.A.1

Extend concepts of putting together and taking apart to add and subtract within 10.
