What mastery looks like

  • Spell words with suffixes -ation (e.g., information, sensation), -ly (e.g., sadly, gently, happily), and -ous (e.g., famous, enormous, various)
  • Spell words with less common vowel patterns: /ɪ/ as y (e.g., myth, gym), /ʌ/ as ou (e.g., young, touch, double)
  • Spell words with endings /ʒə/ as -sure (e.g., measure, treasure), /tʃə/ as -ture (e.g., creature, furniture), /ʒən/ as -sion (e.g., division, television)

Check your understanding

Can Suffixes (age 7+) spell words with endings like "-tion," "-ous," or "-ly" correctly — for example, "nation," "famous," or "quietly" — without needing to look them up?
