## Related Resources

The various resources listed below are aligned to the same standard, (2NBT06) taken from the CCSM (Common Core Standards For Mathematics) as the Addition and subtraction Worksheet shown above.

*Add up to four two-digit numbers using strategies based on place value and properties of operations. *

### Worksheet

#### Slightly Different

- Adding 3 Numbers (in easiest order) e.g. 27 + 13 + 15

#### Three or more

- Three 1-digit numbers e.g. 3 + 4 + 8
- Three 2-digit numbers e.g. 35 + 14 + 26
