Word Families and Root Words

CONCEPTUAL

English›Vocabulary|Ages 7—9|ID: mt_p1imGSFgJT

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 [child] knows the word "cycle," can they work out what related words like "recycle," "bicycle," or "cyclist" mean by thinking about the shared root?”
