There are lot of free resources on the web for kids to visit in order to learn Italian.
If you want to have an example of what I am saying, try to visit the website English For Kids.
English For Kids is basically for parents and teachers trying to help their kids study English. You will find a guide to the materials you need in the Teacher and Parents section of the site. Since these resources have been prepared by ESL professionals with at least 5 years teaching experience, you will find this site a great help.
