This activity is a great way to introduce students to everything an animal needs to survive in a living system. They can also compare and contrast their needs to that of an animal with the optional writing activity that is attached. I've made it very easy to print so that your windows are all different colors like my example. Simply print the house on brown paper and each other page on a different color. Students cut out and glue. You can also choose to have students draw picture examples in each window to show examples of water, shelter, food, and air.
