Find a set of attractive posters (PDF) to exlain learning styles at this website (scroll down completely!):http://www.teachingideas.co.uk/more/pshe/contents.htm
There are also labels you may want to use.
An attractive way to deal with MI in class is by doing some activities specific for each intelligence, e.g. asking pupils to use their arms to show the time to a classmate (kinaesthetic / body smart), organising vocabulary into categories or a logical sequence of their own choice (logical-mathematical + kinaesthetic), etc. After having done these activities ask pupils for their preferences by having them stand by ‘their’ poster and pick up their label. Use the posters to explain some more what kind of activities cater for the pupils’ preferred intelligences and ask if they recognise this. Try to refer to activities you normally do in language class if you can.
Let me know your ideas on how to use these posters!
