Represent and solve
problems involving
addition and subtraction.
1.OA.1 Use addition and subtraction within 20 to solve word
problems involving situations of adding to, taking from, putting
together, taking apart, and comparing, with unknowns in all
positions, e.g., by using objects, drawings, and equations with a
symbol for the unknown number to represent the problem.
NY-1.OA.1 Use addition and subtraction within 20 to solve
one-step word problems involving situations of adding to,
taking from, putting together, taking apart, and/or
comparing, with unknowns in all positions.
Note: Problems should be represented using objects,
drawings, and equations with a symbol for the unknown
number. Problems should be solved using objects or
drawings, and equations.
1.OA.2 Solve word problems that call for addition of three whole
numbers whose sum is less than or equal to 20, e.g., by using
objects, drawings, and equations with a symbol for the unknown
number to represent the problem.

Understand and apply
properties of operations
and the relationship
between addition and
subtraction.
1.OA.3 Apply properties of operations as strategies to add and
subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also
known. (Commutative property of addition.) To add 2 + 6 + 4, the
second two numbers can be added to make a ten, so 2 + 6 + 4 = 2
+ 10 = 12. (Associative property of addition.)
Note: Students need not use formal terms for these properties.
NY-1.OA.3 Apply properties of operations as strategies to
add and subtract.
e.g.,
• If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known.
(Commutative property of addition.)
• To add 2 + 6 + 4, the second two numbers can be added to make
a ten, so 2 + 6 + 4 = 2 + 10 = 12.
(Associative property of addition.)
Note: Students need not use formal terms for these
properties.
1.OA.4 Understand subtraction as an unknown-addend problem.
For example, subtract 10 – 8 by finding the number that makes 10
when added to 8. Add and subtract within 20.
