Recognising and remembering the different forms that a letter can take increases children’s awareness as they see them in other contexts and begin to use them in their early writing. The simple game play of this visually-engaging app follows the rules of pelmanism. Select a pair of letter pebbles, hear their name and sound and watch to see if they match. If a pair is found, they remain face up. If not, they turn over. Try to remember what you saw though as you might need some of those pebbles later! When a game is over, a new set of pebbles appears with letters selected randomly. Teacher options allow you to choose what matching takes place: lowercase to lowercase, uppercase to uppercase or uppercase to lowercase. FEATURES - Learn the name and sound of each letter and its lowercase/uppercase shape - Turn a pair of pebbles to find matching letters - Use settings to choose matching options: UC-UC, lc-lc or lc-UC - Use settings to reduce/increase the number of pebbles used in a game - A Read Me file with guidance on other ways to support letter recognition in children - No third-party advertising - No in-app purchases.
