# MA.K.NSO.3.2

Add two one-digit whole numbers with sums from 0 to 10 and subtract using related facts with procedural reliability.

### Examples

Example: The sum 2+7 can be found by counting on, using fingers or by “jumps” on the number line.

Example: The numbers 3, 5 and 8 make a fact family (number bonds). It can be represented as 5 and 3 make 8; 3 and 5 make 8; 8 take away 5 is 3; and 8 take away 3 is 5.

### Clarifications

Clarification 1: Instruction focuses on helping a student choose a method they can use reliably.
