- ACMNA052 Recognise, model, represent and order numbers to at least 10 000
- ACMNA053 Apply place value to partition, rearrange and regroup numbers to at least 10 000 to assist calculations and solve problems
- ACMNA054 Recognise and explain the connection between addition and subtraction
- ACMNA055 Recall addition facts for single-digit numbers and related subtraction facts to develop increasingly efficient mental strategies for computation
- ACMNA056 Recall multiplication facts of two, three, five and ten and related division facts
- ACMNA057 Represent and solve problems involving multiplication using efficient mental and written strategies and appropriate digital technologies
