What is wrong communication mat

When children are non-verbal or have trouble communicating it can be frustrating and difficult for them. These visual aids for basic communication can help children to express their needs and can help to prevent problematic behavior that may arise as a result of communication barriers. This mat is designed to help children express what is wrong.  
Shown on the mat is: 
* I need the toilet
* I feel sick
* I'm in pain
* I'm too hot
* I'm hungry
* I'm too cold
* I don't understand
* I'm tired
* I'm thirsty
