Letter & Number Tracing is a great way for children to practice letter and number formation. Children can choose to trace uppercase letters, lowercase letters or numbers. A guide will appear before each stroke to show where lines should start and stop. At ABCya.com we like to listen to music while working. We thought it would be fun to have music play while children trace. There are four types of musical themes to choose from: Pop, Rock, Classical and Island. We hope you enjoy it. Finally, there is a fun bonus game at the end where children must put numbers or letters in order to make a musical beat!
