Anything that makes learning or rehabilitation easier is a great thing. Here are some resources I have found that you may be interested in.
iLearn Interactive's Talking Dice has Visual Auditory Kinesthetic properties and are used in the classroom, for special needs and for Speech & language therapy.
Because they are picture based, the dice can be used to teach ANY first or second language in a variety of ways. Combining visual and oral practice really helps the learning process and aids long term retention.
Talking Dice will encourage your students to speak and think in any first or second language. Using curriculum based topics students roll the dice and say what they see in the target language.
