Prepositions

English · Grammar & Punctuation · language

Understand and use the most frequently occurring prepositions of location and direction (e.g. to, from, in, out, on, off, for, by, with)

What mastery looks like

  • Use prepositions correctly in sentences (e.g. 'on the table', 'under the bed')
  • Follow instructions involving prepositions (e.g. 'Put the book on the shelf')
  • Describe positions using prepositional phrases

Check your understanding

If you ask Prepositions to describe where something is — like where the cup is on the table — can they use little words like "on", "under", "next to", or "by" correctly?
