Use counting and subitizing strategies to explain addition and subtraction.- Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
- Use conceptual subitizing in unstructured arrangements with totals up to 10 and structured arrangements anchored to 5 or 10 (e.g., ten frames, double ten frames, math rack/rekenrek) with totals up to 20 to relate the compositions and decompositions to addition and subtraction.

Add and subtract within 20.- Demonstrate fluency with addition and subtraction facts with sums or differences to 10 by counting on.
- Demonstrate fluency with addition and subtraction facts with sums or differences to 10 by making ten
- Demonstrate fluency with addition and subtraction facts with sums or differences to 10 by decomposing a
number leading to a ten.
Example: 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9 - Demonstrate fluency with addition and subtraction facts with sums or differences to 10 by using the
relationship between addition and subtraction.
Example: Knowing that 8 + 4 = 12, one knows 12 - 8 = 4. - Demonstrate fluency with addition and subtraction facts with sums or differences to 10 by creating equivalent
but easier or known sums.
Example: adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13

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). |

New York State Next Generation Learning Standards:
1.OA.6
|
- Add and subtract within 20. 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; and
e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4
- creating equivalent but easier or known sums.
e.g., adding 6 + 7 by creating the known equivalent
6 + 6 + 1 = 12 + 1 = 13
- Fluently add and subtract within 10.

Add and subtract within 20, demonstrating fluencyG with
various strategies for addition and subtraction within 10. Strategies
may include 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. |

Use multiple strategies to add and subtract within 20.- Flexibly and efficiently add and subtract within 10 using strategies that may include mental images and composing and decomposing up to 10.
- Add and subtract within 20 using objects, drawings, or equations. Use multiple strategies that may include counting on; making a 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).
