Metals and Non Metals

If we are teaching metals and non metals to high students.If we ask some examples of metals,students will be able to tell that iron,gold, copper and aluminum etc. Yes it is good examples of metals only but if we ask about examples of non metals,students will say that plastic,wood and rubber etc. But these are not exactly examples of non metals,because plastic belongs to polymer group and wood belongs to fabric group.
