The backgrounds have a grid of white crayon drawn on them with a pattern in each square. The children took pride in their patterns. They put blue dye over the page when it was complete.
The trees are brown corrugated card triangles which I cut prior to the class beginning. They are collaged in tissue paper. We made up some rules. Every piece of tissue had to touch a different colour. The pieces had to be about thumb size or smaller. The brown cardboard had to be covered.
They added glitter which always seem to delight children and horrify cleaners. So I manned the glitter tray, which the children dipped their trees into. They had put little dots of PVA where they wanted the glitter to go.
They added a little trunk and an ornament at the top before attaching the tree to the backgrounds.
