Lesson Plan version 1.1 activities
1. Ask the students to collect symmetrical images of various objects from newspapers, magazines or other sources and stick them on a chart paper. These charts can be displayed in the classroom
2. blackboard. Ask the students to come one by one to the blackboard and draw the line or lines of symmetry for the images. The students can also be asked to cut out a few shapes and fold the shapes
along their lines of symmetry.
3. Bring a mirror to the classroom and place an object in front of it. Now, ask the students to compare the object and its mirror image. Discuss about the shape and the size of the mirror image, mirror line and how the left and the right sides of an object appears reversed in its mirror image. Also, talk about
how the mirror line is not always up-down or left-right but can be in any direction. Then, place a few letters of the English alphabet in front of the mirror. Ask the students to identify the letters, whose mirror images appear the same as well as the letters, whose direction appears reversed in the mirror. Once this activity is done, draw a few letters on the blackboard and ask the students to draw their mirror images. Also, ask the students to identify the letters that have a horizontal line of
symmetry and those with a vertical line of symmetry.
