Learning journey

Your child is building the foundation for reading — learning how letters and sounds work together, recognizing common words by sight, and developing the skills to sound out new words independently.

Evidence of understanding

  • Read words with variable vowel sounds (e.g. 'ow' in 'cow' vs 'snow')
  • Decode words with diphthongs (e.g. 'cloud', 'blue', 'pie')
  • Read words ending in -y pronounced as /ee/ or /igh/ (e.g. 'happy', 'my')

Assessment prompt

Can Diphthongs and complex vowels read words like 'town', 'cloud', 'flew', 'claw', or 'pie' — spotting the special vowel combinations and saying the right sound for each one?
