What is a short vowel?
Short vowel sounds are the foundation of decoding. Once a reader can hear and write the five short vowels inside simple consonant-vowel-consonant words, most of the early reading code opens up.

How to teach it
- Say the sound on its own first, several times, before showing any letters.
- Show the spelling and name it explicitly — tell the reader what it says rather than asking them to work it out.
- Blend two or three words from the list together, out loud, slowly.
- Read the decodable book above, where the pattern repeats in real sentences.
- Come back to it two or three days later. Cumulative review is what makes it stick.
