Word Families and Root Words
词族与词根
Description
Explore word families based on common root words, understanding how words are related in form and meaning through shared roots, prefixes and suffixes (e.g., solve → solution, solver, dissolve, insoluble)
Mastery Evidence
- Generate at least 4 words in a word family from a given root (e.g., from 'play': player, playful, replay, playground)
- Explain how members of a word family are connected in meaning (e.g., 'solve, solution, dissolve all relate to finding answers or breaking apart')
- Use knowledge of a word family to predict the meaning of an unfamiliar member (e.g., knowing 'act' helps understand 'actor', 'action', 'react')
Assessment Prompt
If your child knows the word "cycle," can they work out what related words like "recycle," "bicycle," or "cyclist" mean by thinking about the shared root?
