Creating Speaking Avatars

http://www.voki.com

is an excellent tool to develop students' imagination and practise the English language. 

Advantages: 

• It is free and embeddable in blogs and wikis
• Registration is optional
• Stimulates imagination and creativity
• Young learners love it !

Disadvantages:

• Students may spend too much time on the avatar's design
• You may not record your voice properly
• Embedding avatars on blogs may be difficult for teachers and students with weak tech - skills

Possible Activities:

1- Introduce yourself, say what you did last weekend, say your plans for next holidays, etc. 
2- Teacher asks questions about a given topic and Students write the answers in the section "comments" in Blogger .

I have used it with young learners and the results were very good. Let me show you some examples:
