Hello dear colleague
I �m going to give you some ideas & I don �t know if you can achieve it :
1-Ask your students the lesson before the demonstration one to bring the needed elements for decoration as stated in the text & to bring items stated in let �s get ready step ;
2-before lesson time try to rearrange the classroom so that to have an epmty space ,where you can move easily & decorate it; when you start your lesson (let �s get ready p65:use the real material to start your lesson :refreshements ; food ....====all these steps can make it very easy to move to the reading : view the scene & feel the atmosphere !
3-step 2 (the song personally I do it after the second part of the text !),then ask them to do project work : ask a pupil to read it & you �ll try to explain it !
4-Finally : You can do step 4 next lesson
It �s a suggestion , hope you find it useful !!!!!!
