| 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. |

| 1.OA.B.3 Understand and apply properties of operations and the relationship between addition and subtraction. | ||
|
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
porperty of addition.) |

| Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8+6=8+2+4=10+4=14); decomposing a number leading to a ten (e.g., 13-4=13-3-1=10-1=9); using the relationship between addition and subtraction (e.g., knowing that 8+4=12, one knows 12-8=4); and creating equivalent but easier or known sums (e.g., adding 6+7 by creating the known equivalent 6+6+1=12+1=13). |

1.OA.B.3 Apply properties of operations as strategies
to add and subtract. (Students need not use formal terms for these
properties.) 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, which equals
12. (Associative property of addition.) ISTE Student Standards Addressed: 1. Empowered Learners 5. Computational Thinker |
