Notice the different geometric shapes in your set of tangrams. Which shapes can you name? What new shapes can you make with your set of tangrams? Start by discussing different ocean habitats. Look at different types of animals and plants and talk about the colors and shapes that comprise the image. Ask students to name different kinds of flowers: daisies, roses, sunflowers, tulips, lilies, dandelions, etc. To include a science element into the lesson, discuss with students how insects use flowers. Ask students about the different kinds of bugs they've come across while outdoors. How large are the bugs? What shapes and sizes were they? Create vibrant sea turtles with this art lesson plan using crayons and watercolor. Ask students to define an endangered species. See if they know of any endangered birds. Use pictures of the birds to continue the discussion on colors, texture and habitat. Discuss different animals from various geographical areas. Have them choose animals that are protected, extinct animals, arctic animals or whatever animals they are interested in.
