This pack contains 15 sets of dominoes (each set has 18 dominoes). The dominoes are made up of pictures and their initial sound. There are a range of pictures for each letter to avoid a single letter-picture association being formed. Each set is colour coded to help distinguish between them. This activity is great for letter and sound identification/recognition and helps children identify the initial sound of a word. I hope you find this activity useful. Thank you for your support.
