English · Grammar & Punctuation · procedural

What mastery looks like

  • Identify the preposition and noun phrase within a prepositional phrase, e.g. in 'under the old bridge', 'under' is the preposition and 'the old bridge' is the noun phrase
  • Add prepositional phrases to expand sentences with detail about where, when, or how, e.g. 'The cat slept' → 'The cat slept on the warm windowsill throughout the afternoon'
  • Distinguish prepositional phrases functioning as adjectives (modifying nouns: 'the house on the hill') from those functioning as adverbs (modifying verbs: 'she ran across the field')
