Help children learn about snakes and how they move by making a paper chain they can turn into a snake. Gather the materials to make this craft -- construction paper (in two shades of green and red), markers, scissors, and transparent tape or glue. Cut the green construction paper into 1-inch-thick strips lengthwise. Have children take a strip, make a circle and secure it with glue or tape. To continue the chain, insert the second green-colored paper through the circle and make a new link. Continue until the snake has reached the desired length. Let children draw the face of the snake on the last ring. Use the red paper to make a tongue to glue onto the face. When completed, talk about how snakes move and have children demonstrate the movement with their chain snake.
As a group, learn about the different parts of frogs, their habitats and how they move around. Explain and demonstrate how frogs jump by using their hind legs. Afterward, get the entire class involved to play a game of leap frog on the playground. Have the children croak or "ribbit" each time they hop over the child in front of them.
Have a special story time every day when you read books about different reptiles. Reptile-themed books include "Slithery Jake" by Rose Marie Provencher, "The Greedy Python" by Richard Buckley and Eric Carle, "Snakes and the Boy Who Was Afraid of Them" by Barry Louis Polisar and "In the Small, Small Pond" by Denise Fleming. Ask each of the children to bring books about reptiles from home to share with the class.
Play reptile-themed songs that children can sing along with as they act out the different motions from the songs. For example, when singing about a snake, have the children slither across the floor. When singing about an alligator, have the children use both arms to make a chomping motion.
