Add and subtract one- and two-digit numbers, representing problems using number sentences and solve using part-part-whole reasoning and a variety of calculation strategies.
What this means

- Number sentences; equation, e.g. 25 + 17 = 42
- Calculation strategies; partitioning, bridging ten, doubles, near doubles.
Tips
- A part-part-whole diagram will help students interpret and solve addition/subtraction problems.
