A quick C&P - not the full article but a bit of it. There lots more to do with finding halls, advertising etc but it's a bit long in one go!
"Sessions (approximately 45 minutes for toddlers and pre-schoolers) are broken down into an underlying structure which is repeated each week. Although the themes and songs change weekly, the structure is the same so the children are aware of what happens next and are confident in the class.
Each session consists of:
a welcome song where all the children are greeted by name;
an original "song of the term" which tends to be a gross motor skill song e.g. hand clapping, foot stamping, bouncing/jumping. This is repeated for 5 weeks before changing;
the weekly themed section using mostly familiar action songs and nursery rhymes;
a listening section which features live music on a variety of instruments. This sometimes includes movement or 'active listening' where the children can respond to the music play by using scarves or ribbon sticks;
a ?musical element? section using percussion instruments and looking at a particular musical element each week (e.g. tempo, rhythm, beat, dynamics etc);
and finally the really fun part with some games with a play parachute or stretchy lycra sheet, movement activities (ribbons, scarves, balls or hoops) and a bubble machine.
Then it's the goodbye song and everyone leaving."
I?ve done lots of experimenting over the past years and I think I know what my class members want but this is something you will need to do by trial and error to find what works for you.
