The various resources listed below are aligned to the same standard, (2NBT07) taken from the CCSM (Common Core Standards For Mathematics) as the Addition and subtraction Worksheet shown above.

*Add and subtract within 1000, 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. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds. *
