???The Jolly Phonics Letter Sound Strips is a pack that contains 30 identical reference strips to assist children in their writing. Each strip shows the 42 main letter sounds on one side and the main alternative vowel spellings on the other. For this new edition for 2021, each set of letter sounds has been colour- coded to match the colours used across other Jolly Phonics resources. The artwork for each letter sound has also been updated as part of our fresh and vibrant new look.
