Lesson Plan
[Author - Kripa S]
Objective: To introduce congruency and similarity of figures
Subtopics to be covered:
- What is congruency, what is similarity
- Identify congruent or similar figures in given set of figures
- Ratio to define the similarity of figures
- Symmetry ( mirror, rotational, point)
Learning Outcome:
- Students can identify congruent shapes and similar shapes
- Students can tell the ratio of change for similar shapes
- Students can identify the type of symmetry for a given shape

Activities

1. Take a piece of paper.Remember each paper should be of same size.Measure the length as well as breadth of the paper.Fold and use it to make an ‘aeroplane’.Compare and observe whether the size of this aeroplane still remains the same or not.
