Evaluating a website

I decided to evaluate the website.. http://www.abcya.com
How easy is it to navigate? It's really easy to use and get around. The different pages are seperated by different grades which makes it easier for children using it. It's also bright and colourful and clearly labelled.
Are there any help/guide videos? At the start of each game there are instructions but nothing further which might be difficult for some children.
Do you need to register? No
Is it free? Aspects that are free? Yes the site is free to use.
Is it easy to use? Yes it is really easy to use. Everything is clearly labelled.
What multimedia aspects are there? Most of the games came with animations.
Does it provide enbeded codes?
