We are reading on our MACbook Laptops!

We have been learning how to log in to the school MACbook Laptops. 
Each child has a large log in card with their log in codes. They are learning the steps to log on and then reading on RAZ-Kids. The kids really enjoy it and are getting better at logging in. 
It is a really hard lesson for them to learn that the computers need their names to be spelled EXACTLY right, no invented spelling and no forgetting letters! 
It is quite funny when a child says "My computer won't work"
When I go over the first thing I check is how they spelled their name and that's usually what the problem is! They have left out a letter or two! 
Computers can be so fun and so frustrating too! LOL!
