One idea for fall bulletin board decorations are to use real leaves, sticks, nuts and other fall items from nature. Another idea is to create a funny play on words using seasonal inspiration.
Attach a real or plastic autumn leaf garland to the edges of a bulletin board for a seasonal border. Use branches, pine cones, acorns, leaves and other autumn objects to decorate a bulletin board. Some fun ways to incorporate fall words are to spell out sayings such as "Nuts About Reading," "Fall Into Learning" and "Math is Bushels of Fun." Another fun idea for a classroom bulletin board is to have students put their names on paper leaves, and then attach the leaves to a "tree" on the bulletin board. The tree can be painted on or created using paper or other craft supplies.
