Subtract multiples of 10 from multiples of 10 in the range 10-90 (positive or zero differences), 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 and explain the reasoning used. |

New York State Next Generation Learning Standards:
1.NBT.6
|
Subtract multiples of 10 from multiples of 10 in the range 10-90 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 used to a written representation and explain the reasoning.
Note on and/or: Students should be taught to use concrete models and drawings; as well as strategies based on place value, properties of operations, and the relationship between addition and subtraction. When solving any problem, students can choose to use a concrete model or a drawing. Their strategy must be based on place value, properties of operations, or the relationship between addition and subtraction.
Note: A written representation is any way of showing a strategy using words, pictures, or numbers. |
