							Christmas hidden pictures 2 
							Part 2
Sorry, I had to upload the whole ppt in two parts as it exceeded the 3 MB-limit as a whole.
The students form 2 groups.
They will see  a grid with numbers. 
The group in turn should choose a number.  Klicking on this number, a part of the picture will be revealed.
After a box is revealed, the OTHER group (NOT THE GROUP IN TURN!) has 10 seconds to guess what the whole picture is. (So, the groups should choose a number tactfull if they don’t want to reveal something FOR THE OTHER GROUP!)
If the other group cannot guess, they should choose a number for the other group, and so on. 
If a group guesses right, they will get as many points as there are left unrevealed.
If their guess is incorrect, they lose and all the points are given to the other group.
