Subtraction
3rd Grade


Alabama Course of Study Standards:
11

Use various strategies to add and subtract fluently within 1000. 
Arkansas Academic Standards:
3.NBT.A.2

Using computational fluency, add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and the relationship between addition and subtraction
Note: Computational fluency is defined as a studentâ€™s ability to efficiently and accurately solve a problem with some degree of flexibility with their strategies. 
Common Core State Standards:
Math.3.NBT.2 or 3.NBT.A.2

Fluently add and subtract within 1000 using strategies and algorithms
based on place value, properties of operations, and/or the relationship
between addition and subtraction. 
Georgia Standards of Excellence (GSE):
3.PAR.2.1

Fluently add and subtract within 1000 to solve problems. 
North Carolina  Standard Course of Study:
3.NBT.2

Add and subtract whole numbers up to and including 1,000. Use estimation strategies to assess reasonableness of answers.
 Model and explain how the relationship between addition and subtraction can be applied to solve addition and subtraction problems.
 Use expanded form to decompose numbers and then find sums and differences.

New York State Next Generation Learning Standards:
3.NBT.2

Fluently add and subtract within 1,000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. Notes: Students should be taught to use strategies and algorithms based on place value, properties of operations, and the relationship between addition and subtraction; however, when solving any problem, students can choose any strategy. A range of algorithms may be used. 
Tennessee Academic Standards:
3.NBT.A.2

Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
