It's torn paper art!
Fold colored Xerox paper in quarters; I used pale green paper. Then outline a tree shape in pencil. Kids will color their tree.
Provide the children with construction paper scraps and glue. They'll tear the scraps into tiny pieces and glue them inside the tree shape. They can use any colors and designs they'd like. Save a yellow piece for the star at the top.
Tip: give each child a plastic tray to collect their tiny paper pieces before gluing.
It's a beautiful, frame-able, torn paper art tree.
