Letter Sound Activity Sheets 26 letters of the alphabet ( including sh -a full digraph set coming soon!) Each mat focuses on a single letter and has an activity to match the letter sound. Recommendation to laminate each mat and use a variety of resources to complete the activity. This could be whiteboard pens, playdough or plastercine. You could photocopy particular ones and children could use felt tip pens, pastels or water colour paints. There is a section on each mat for the children to practise the letter formation. Font: Poppins A seperate set is available with the Read Write Inc letter images.
