Students are given 4 or 5 rectangles of green paper and shown how to find the center of one side by folding it. They then cut 4 or 5 green triangles, each one slightly larger than the next. (Alternately, students could paint a paper with various green tones and cut their triangles from that when it's dry.)
The triangles are glued together and a brown rectangle is glued to the bottom as a trunk.
Black paint is scraped on with wood tools to provide variety and each tree is glued to a white background paper. When the glue and paint is dry the trees are cut out leaving a white edge around the tree.
