Devide your paper into four equal sections. This can be done any way you want, but try to have each section ake up about a quarter of the paper. Don't worry, it doesn't have to perfect.
In each section, colour in a colour or a pattern that represents to you each one of the seasons. Commonly green for spring, yellow for summer, orange or red for fall and blue or grays for winter,
With a pencil draw a simple tree that either overlaps all four areas like the four examples here or a tree in each section seperatly.
Once you have the tree the way you want it, colour it in with a black pencil crayon or marker.
