This is a good way for students to check if their Chinese writing is legible. If the computer can't guess at what it may be, maybe they need to keep working at it. Built for success and great for interactive whiteboards.
This tool takes a sentence in Chinese (not pinyin unfortunately) and gives an English or French translation for every word individually. Very good for breaking up sentences into small parts, for analysing word-order and for students to check their writing.
This is one of the best Chinese-English dictionaries on the internet, when you consider that so many of the words have audio and an animation of the stroke order for writing.
This is a fantastic resource for any classroom learning Chinese or about China. The dictionary pinyin with tones as well as simplified and traditional writing, an animation of the order stroke for many words and audio of how the word should be spoken. There is also other resources such as practice sheets for writing, a translator, and other stuff for kids and the classroom.
This is a superb site for finding downloadable podcast for kids to learn Mandarin. Not all the resources are free, but there are lots of really useful resource that are, including over a hundred audio files lessons and for learning pinyin.
