A superb app for any one looking at learning basic Mandarin Chinese. Play the game to listen and see the language. There are many different types of questions, but most are multiple choice or click and drag from a selection of choices. Questions start out easy and there is support and 'hint' buttons to help you. You can download each lesson as you reach it, or download everything if you plan to use it offline. All the language you have met is stored in a word bank and use your microphone to compare your pronunciation to the recordings.
This site has many great pictures and information about sites all over the world. The Education tab gives you lesson plans as well for some of the sites. Click on 'find a location', and you are brought to several possible areas around the world. Additional information is available by clicking on the arrows along side the pictures.
For ALL preschool and Kindergarten age children and English learners. The Kindersite has 1,000s of links to the best games, songs and stories for young children.
