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
This is a great independent practice activity on food chains. Students could research a food chain and then display it on index cards. The students will draw each animal on an index card then attach them together in food chain order with string or yarn.
