Sign in to track this

What mastery looks like

  • Say the most common sound for each consonant when shown the letter
  • Distinguish short vowel sounds in CVC words (e.g. /a/ in 'cat' vs /e/ in 'bed')
  • Associate long and short vowel sounds with common single-letter spellings

Check your understanding
