Help your preschoolers create a spider web using a marble, black paint, baking pan with tall sides, light-colored construction paper and spider stickers. Cut a piece of light-colored construction paper and put it in the bottom of the pan. Let a student hold the pan while you drop a paint-covered marble in it. Show her how to tilt the pan back and forth, making the marble roll over the paper. This creates a spider web. After the paint dries, place a black spider sticker in the middle of the web. Instead of the sticker, you can glue a small, black plastic spider to the web. Black, plastic spiders are available online and at many retail stores, especially around Halloween.
Draw or print a picture from the Internet of a rain cloud, sun, rain gutter and a spider. Cut out pieces and laminate each one. Place the pictures in a plastic zipper bag. Make enough for each preschooler to have a bag of "Itsy Bitsy Spider" characters. Have the preschoolers get out their pieces and sing the nursery rhyme. While singing the rhyme, the students can hold up each character as it corresponds to the song.
Give each student a piece of construction paper and glue. Help each child make thin lines of glue in the shape of a spider web all over the paper. Sprinkle glitter over the picture and shake off excess glitter. After the glue dries, poke a hole in the middle of the spider web. Tie a piece of string around a plastic spider and put the string through the hole. The preschoolers can pull the string from the back of the picture to make the spider move up and down.
Purchase black paper plates and googly eyes to make plate spiders. Glue the eyes on the backside of the plate. Take strips of black construction paper and fold them accordion-style to create the legs. Glue the legs to the plate. Draw a large waterspout on poster board and hang it on the wall. One child can use his plate spider, one can hold a picture of the sun and one can hold a rain cloud. Rehearse the song and let the children move the items as they correspond to the song.
