Have the students actually make a Holiday chain to glue their food chain to! Check out the awesome FREE Food Chain Display Template at Teachers Pay Teachers: http://www.teacherspayteachers.com/Product/Food-Chain-Display-Template-1291556
After discussing food chains, students will draw and write about a food chain. Encourage students to use academic vocabulary they are currently learning. This activity can be adapted for many grade levels-from simple labeling and writing for Kinder and First to more detailed writing for second and up.
