It is a great website as it includes many aspects of English language teaching - from teaching vocabulary and listening comprehension to grammar.
There are many entertaining cartoon clips to watch, songs to learn and games to play. It is a great resource to use with a small group on the smart board as the students can watch a story then you can ask them questions to check their understanding. It is also a great website for kids to use independently and can even be given as an activity to do at home. I tend to use this website with older new arrival students and younger students who need further vocabulary and comprehension reinforcement.
