What students learn in AC9E5LY10
This unit helps students build a clear, usable understanding of Less common plurals, and understand how a suffix changes the.... 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: explore less common plurals, and understand how a suffix changes the meaning or grammatical form of a word.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- using knowledge of word origins and roots, and related words, to interpret and spell unfamiliar words, and learning about how these roots affect plurals; for example, “cactus” and “cacti”, “louse” and “lice” understanding how some suffixes change the grammatical form of words; for example, “-tion” and “-ment” can change verbs into nouns: “protect” to “protection” and “develop” to “development”
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
