With Christmas coming up why not make these adorable reindeer? When I was doing my practicum, my supervising teacher made these with the class.
You will need brown paper bags, black card (antlers), your choice of cardboard (ears), white and coloured paper for eyes and nose. We added little bits of tinsel to look 'Christmassy'. You could also make these as part of a unit on Animals.
These murals were a wonderful way of decorating the classroom. I drew the outline in pencil and children painted it. When they had finished, I outlined the picture with black paint. Obviously this is not a very creative art activity, however it is a fun activity to do with small groups, perhaps during free choice activity time.
