Standard Identifier: K.NBT.1

Grade: K
Domain: Number and Operations in Base Ten

Cluster:
Work with numbers 11–19 to gain foundations for place value.

Standard:
Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.

Standard Identifier: K.OA.1

Grade: K
Domain: Operations and Algebraic Thinking

Cluster:
Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.

Standard:
Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

Footnote:
Drawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards.)

Standard Identifier: K.OA.2

Grade: K
Domain: Operations and Algebraic Thinking

Cluster:
Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.

Standard:
Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.

Standard Identifier: K.OA.3

Grade: K
Domain: Operations and Algebraic Thinking

Cluster:
Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.

Standard:
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 by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).

Standard Identifier: K.OA.4

Grade: K
Domain: Operations and Algebraic Thinking

Cluster:
Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.

Standard:
For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.

Standard Identifier: K.OA.5

Grade: K
Domain: Operations and Algebraic Thinking

Cluster:
Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.

Standard:
Fluently add and subtract within 5.

Standard Identifier: 1.NBT.1

Grade: 1
Domain: Number and Operations in Base Ten

Cluster:
Extend the counting sequence.

Standard:
Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.

Standard Identifier: 1.NBT.2.a

Grade: 1
Domain: Number and Operations in Base Ten

Cluster:
Understand place value.

Standard:
Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases: 10 can be thought of as a bundle of ten ones—called a “ten.”

Standard Identifier: 1.NBT.2.b

Grade: 1
Domain: Number and Operations in Base Ten

Cluster:
Understand place value.

Standard:
Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases: The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.

Standard Identifier: 1.NBT.2.c

Grade: 1
Domain: Number and Operations in Base Ten

Cluster:
Understand place value.

Standard:
Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases: The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).
