Have a bedtime party in your classroom. Talk about bedtime routines with your preschoolers. Invite the children to share activities they do at bedtime, such as taking a bath, reading a story and brushing teeth. Share what you do to get ready for bed, as well. Bring elements of those routines into your party. Ask the students to wear their pajamas to school and to bring a pillow and blanket. Read a few classic bedtime stories, including "Goodnight Moon," to the children. Review the fact that the bunny is saying goodnight to many objects and invite the preschoolers to tell what they would say goodnight to if they were the bunny.
Build on the moon theme by teaching your preschoolers more about the moon. Show pictures of the different phases of the moon and talk about how each shape is different. Have students cut these shapes out of white paper and glue them onto black paper for a visual image of the different phases. To illustrate the concept of moon craters, students can glue O-shaped cereal to white construction paper circles. Talk about what makes craters, such as space rocks colliding with the surface of the moon. Illustrate this further by bringing a bowl of flour to class, which acts as the moon's surface, as well as several small pebbles. Children drop the pebbles into the flour to see craters form.
Bring in an element of math by calling attention to the various clocks in the story of "Goodnight Moon." Show the hour and minute hand and talk about the differences. Go through the story and talk about what time is on each clock. Practice counting skills by asking the kids to count different objects that appear in the story. For example, preschoolers can count how many times they see the moon or the rug on the floor. Ask the students to point out different shapes they see in the story, such as the round balloon or triangle blanket on the bed.
Write words from the story on slips of paper, stick them in plastic Easter eggs and wrap the eggs in aluminum foil. Hide the "moon rocks" around the classroom and invite the children to find them. Open them up and read the words together. Point out a word in the story and ask the students to volunteer rhyming words they remember from the book, such as "bears" and "chairs" or "kittens" and "mittens."
