This app has 100 popular CVC words in it and your child can tap the bubble to hear how to pronounce the letter using phonics. They must then work out what the word says and find the image that relates to the word.
Once correct the word will then be spoken.
To change the sound from American English to British English ensure the language of your device is set to either English or British English under Settings/General/International/Language.
