Figures with Multiple Symmetry PE

Learning Outcomes

1. The students are able to identify the lines of symmetry in a given figure.
2. They identify the lines of symmetry in a volley ball court.
3. They explore the various courts of the games and make a table of lines of symmetry as a project.

Description Of Activity

How to play

1. The students can be asked to plot those figures on paper.
2. The students were asked to group into 4 or fives and find out the lines of symmetry in a volleyball court and how many pairs of figures and their lines of symmetry.
3. As shown in the video of the URL the players also form the vertices of a hexagon which are symmetric about the lines from different angles which are drawn already or imaginary.
4. The students can be asked to plot those figures on paper.

Drawing a Mirrored Shape

1. Take a piece of graph paper, a pencil, and a ruler and draw a reflecting line down the center of the paper vertically. Draw a geometric figure on one side of the line and then draw its exact reflection on the other side using line segments, points, perpendicular lines, parallel lines, and diagonals. Study the symmetry of the figures. Turn the paper so that the reflecting line is horizontal. Compare how the figure looks from this vantage point with the original facing.
2. Share your graphs with the rest of the class. How might mirrored movement phrases be perceived by an audience? How do we as dancers perceive symmetry while moving? What makes something symmetrical?

Reflection Sequence

1. Find your mirroring partner. Teach each other the 16-count phrases so that when finished, each pair has a 32-count phrase (16 counts from each partner). Partners should begin with the same arm and leg so that they are always using the same side of the body. Practice the 32-count phrase to make sure both dancers can perform it from memory.
2. Face each other and perform the 32-count sequence in a lateral mirroring fashion. Both partners will perform the phrase as they learned it, starting on the same side of the body. This time the movement will seem different because the partners are now facing each other. Symmetry is produced because movement on both sides of the figure is seen simultaneously when viewed front to back. Discuss the ease or difficulty of this exercise.

Variations

Let the children cut the court on sheets of paper and fold the same for verification

Coaching Tips

1. In a volley ball court how many lines of symmetry can be identified and how many pairs of symmetric figures are there?
2. How many lines of symmetry can be identified in dance.
