ABC Mouse is really good for your student and will help them learn and be on task.
If you have a iPod, or iPad please download the app, Spellasaur. It is an app that will help your student be able to spell. It is very fun game that has dinosaurs. I have gotten lots of positive results with the app.
Starfall.com helps with phonics and reading. These are all websites that your student can work on through the summer, that way they do not fall behind.
