What students learn in AC9MFN02
This unit helps students build a clear, usable understanding of And name the number of objects within a collection up.... The goal is not to memorise one answer pattern. Students should be able to explain the idea, recognise it in a new example and apply it in a short practice or worksheet task.
- Start with the main idea: recognise and name the number of objects within a collection up to 5 using subitising.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- recognising how many objects are in a collection or in images on a card with a quick look and saying the associated number without counting playing instructive card games that rely on the recognition of numbers represented in different ways; for example, playing memory games, matching pairs of quantities on dot cards or similar where the arrangement on each is different; using subitising to compare and order collections and to say who has more when sharing items in a game
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
