Consonant Digraphs

English · Phonics & Word Reading · procedural

Read and spell words containing consonant digraphs and less common consonant spellings (ch, sh, th, ck, tch, ng, ph, wh, k for /k/)

What mastery looks like

  • Read words with consonant digraphs (e.g. 'shop', 'chip', 'that')
  • Identify the sound made by ph (/f/) and wh (/w/) in words
  • Spell words ending in -ck (e.g. 'duck') and -tch (e.g. 'match')

Check your understanding

When Consonant Digraphs sees words like 'shop', 'chip', 'ring', or 'photo', can they spot that two letters together make one sound and read the whole word correctly?
