Download 101+ Ideas for Using the BIGmack or Other Single Message Communication Devices

Using the BIGmack:

The BIGmack can store a single message of up to 75 seconds. This can then be replayed with a single press. Changing the message is a very simple process, allowing the device to be used at a moments notice. It is especially useful with children who are more interested in people than things. A child can use it to take messages to another class, answer their name, join in with a song or story with a repeated phrase. In a group situation the child can pick a person by looking at them and then give an instruction by pressing the BIGmack. These activities are excellent for putting switch activity into a social and communication context.
