Under the sheet

I choose 3 children to hide under a sheet, then get everybody to sing Debajo de la sábana. At the end I choose children to name the people hidden under the sheet. I use a tune from Diez deditos 'Debajo del botón'. The document I have loaded turns into a little guessing display presentation when I have put a flap over the main picture, so the children can guess which character is 'Debajo de la sábana'. Sometimes I write the first letter of the character's name on the flap.
