Halloween evokes specific images and sounds. Use both traditional and original songs in the music program within the classroom to celebrate the coming of Halloween. Free materials are plentiful on the Internet. To enhance the literacy program, write song lyrics on the chalkboard for a word association exercise. Use music during physical education as well; encourage the students to express themselves through movement as part of their development. Themes such as black cats, scary trees in the wind and ghostly movement can inspire and stretch out small bodies.
Personal and appropriate expression are important aspects of learning in the primary grades. Putting on plays in the classroom during Halloween is one way to model this behavior in a positive way. You can find short plays and ideas for theatrical expression for children of all ages on many websites for free. Consider getting another class of students involved as an audience -- but not one so big as to frighten young students. Have the mini-plays performed on the day closest to Halloween when children are already in costume at school.
You can instill the idea of civic responsibility throughout the year, and although kindergarten students are extremely young, they are capable of making a difference for others. Since the 1950s, American children have supported the charity UNICEF by taking the traditional orange boxes door-to-door canvassing for change as well as candy on Halloween night in the Trick-or-Treat for UNICEF campaign. You can help children organize to help others in several other ways, such as food and mitten drives; local fire halls and police stations are often eager to help with these types of projects as well.
Halloween crafts are limited only by your imagination. Themes of silly jack-o'-lanterns, colorful ghosts and candy corn are appropriate for the kindergarten age group. Have the children produce crafts using any art supplies already in the class, or ask them to bring in items such as pasta, pennies or pipe cleaners from home to enhance the projects. One option involves cutting out faces on lunch bags and having the students color the bags in a Halloween theme. You can then place flameless candles into the bags to illuminate the faces and artwork.
