Main Objective:

Students will perform, analyze and create transformations.

General Outcome:

Apply positional language, orally and in writing to communicate motion.

Specific Outcomes:

Create symmetrical 2-D shapes by folding and reflecting.

Materials:

Mirrors, birch bark biting samples, red pencils, dry-erase markers, paper, scissors, picture of the “Circle of Courage” or a medicine wheel, and Mira boards

Activity/lesson Ideas:

  1. For this activity you require mirrors and birch bark biting pictures. Idea: print copies off of our website, cut them out and laminate them to get more use. If they are in paper copy, have students use red pencils to indicate all the lines of symmetry that they can. If they are in laminated version, they can use dry-erase markers to indicate all the lines of symmetry. Once they have indicated the lines of symmetry also have them indicate the shapes found within the image. Have them explore different directions of placing the mirror.

  2. For this activity you require paper and pencils. Tell students to take their piece of paper and fold it in half. Show them how to cut a shape of a tipi canvas, with one line of symmetry. You can refer to the still images from the tipi raisings as well for this activity.

    The number four plays a significant role in First Nations culture. First Nations people look at all of the natural things that happen in life in fours. For example we have four stages in our lives: baby, child, adolescent and adult. We also have things such as four seasons: spring, fall, summer and winter. Using paper, have students fold it into fourths. Show them a picture of the “Circle of Courage” or a medicine wheel.

    The four quadrants of the “Circle of Courage” represent belonging, generosity, mastery and independence. The four quadrants of the medicine wheel represent our health in regards to physical, emotional, spiritual, and mental health.

    On the paper that each student folded into fourths, have them illustrate a picture that represents how they practice the values from the Circle of Courage or how they keep healthy in regards to the medicine wheel teachings.

  3. Give each second student a birch bark-biting sample. Have them cut their sample in half and give one half to a friend. Using a Mira board, have students complete the unfinished birch-bark biting.
