Topic : Properties of Rotational Symmetry

Begin the lesson by displaying a picture of some 2D shapes and ask them to identify the slide image, flip image and turn image of each shapes on the projector.

Let them watch this video and ask them to draw shapes like equilateral triangle, an arrow head on the square grid paper and let them rotate it.

Monitor and assist students as they work through the activity, ensuring they understand the concepts and calculations involved.

Divide the class into small groups or pairs. Allocate a computer each for a group and Provide a worksheet 1. https://drive.google.com/file/d/1CDnaHp1-kxnJPgClHHrrGWx8wzamcCZQ/view?usp=share_link Worsheet2:https://drive.google.com/file/d/1rNa9eIijgteoa-g0va3AnnZbh5y4j7ZQ/view?usp=share_link

Present the concept a turn symmetry or rotational symmetry.

2. Describe that the number of times it appears in the identical position during one complete rotation is the order of rotational symmetry.
   

3.  Explore the properties of the rotational symmetry for quadrilaterals and regular polygons.
   

1. Investigate whether the shape has rotational symmetry or not.
   

Provide timely feedback to students as they work.
Praise students who have successfully identified the turn symmetry. Provide corrective feedback to students who may need additional support.

After completing the worksheet, discuss the answers to the class, emphasizing the order of symmetry for each shape.
Assess the performance of each student based on their ability to identify the rotational symmetry
