Letter & Number Tracing is a great way for children to practice letter and number formation. Children can choose to trace upper case letters, lower case letters or numbers. A guide will appear before each stroke to show where lines should start and stop. At ABCya.com we like 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 number or letters in order to make a musical beat!
