Explorar y describir los diferentes tipos de materiales en diversos objetos, clasificándolos según sus propiedades (goma-flexible, plástico-impermeable) e identificando su uso en la vida cotidiana.

I created this resource as an extra activity to revise vocabulary related to classroom objects. 
Students can do it by their own or it can be done with the whole class. For example: Teacher will point a number and asks "Is it a pencil?" Sts have to answer with:  Yes, it is / No, It isn't.  
Also can be used to sts to revise the structure : it's a blue rubber. etc
