Standard Identifier: 1.NBT.1

Grade: 1
Domain: Number and Operations in Base Ten

Cluster:
Extend the counting sequence.

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).

Standard Identifier: 1.NBT.3

Grade: 1
Domain: Number and Operations in Base Ten

Cluster:
Understand place value.

Standard Identifier: 1.NBT.4

Grade: 1
Domain: Number and Operations in Base Ten

Cluster:
Use place value understanding and properties of operations to add and subtract.

Standard:
Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.

Standard Identifier: 1.NBT.5

Grade: 1
Domain: Number and Operations in Base Ten

Cluster:
Use place value understanding and properties of operations to add and subtract.

Standard Identifier: 1.NBT.6

Grade: 1
Domain: Number and Operations in Base Ten

Cluster:
Use place value understanding and properties of operations to add and subtract.

Standard:
Subtract multiples of 10 in the range 10–90 from multiples of 10 in the range 10–90 (positive or zero differences), using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
