===Learning objectives===
# Four sided closed figures are called quadrilaterals.
# They are of different types.
# Grouping is made based on angle measures and/or sides.
# Each type is recognised with its characteristic properties.
# The types include parallelogram (square, rectangle, rhombus,) and non-parallelograms (trapezium and kite).
===Notes for teachers===
===Notes for teachers===
# This activity can be done after teaching the students about different types of quadrilaterals and their properties.
# This will help clarify similarities and differences between different quadrilaterals.
# Can do in group of 3 students to enable discussions.
