# Australian Curriculum v9 crosswalk · Year 4 maths Weeks 3–4

These are **partial content-description links**, not a complete Year 4 curriculum or achievement-standard judgement. Week 3 names/places tenths and hundredths (`AC9M4N01`); Week 4 makes exact equivalent fraction and decimal representations (`AC9M4N03`), using place-value notation where appropriate (`AC9M4N01`). In every comparison the unit whole is fixed and its parts are equal. A two-week encounter does not establish full mastery.
