Activities: 
Play the video titled “Birch Bark Biting” and have the students look for examples of symmetry throughout the video. After the video, ask the students whether or not they are able to think of examples in nature which are symmetrical such as: tree leaves, faces of animals and people, grass, butterflies, flowers. Handout the image of birch bark biting which is found in Examples of Birch Bark Biting. Have the students draw lines across their paper which demonstrates the lines of symmetry. Take the students outside into the schoolyard and assemble in groups of three. Ask the students to find three different objects which are symmetrical and to draw these objects in their math journals with a broken line to indicate the lines of symmetry. 

Teacher preparation: 
Have the video ready to play for the students. Print sufficient copies of the Examples of Birch Bark Biting for the students. Have an example of symmetry found outdoors (e.g. the ladder attached to the play structure). If possible bring in some examples from nature that illustrate symmetry such as grass or leaves.
