My favourite Tip:

Paper on the floor!

This is a very good exercise to finish the class.

Repeat this chant (or sing it to the tune of Frére Jacques)

I see a paper (2)

Pick it up (2)

Throught it in the litter bin (2)

Tidy up (2).

I´m sure your pupils will enjoy this activity and tidy up the classroom.
