{{Geogebra|wbdsvtbp}}'''Procedure:'''
# The teacher can use this geogebra file to introduce parallelograms to students.
# Move the vertices A or B or D and observe different parallelograms formed like square, rectangle and rhombus.
# Bring their attention to measures of sides, angles and diagonals.
* Developmental Questions:
# Can you identify the figure ?
# How many sides does this figure have ?
# What do we call a figure with 4 sides ?
# Are all 4 sides equal ?
# What are parallel lines ?
# Identify the 2 sets of parallel lines.
# Spell out the differences between the figures formed with respect to sides, angles and diagnols.
# What common features do you observe in all figures/shapes formed ?
=== Evaluation at the end of the activity ===
=== Evaluation at the end of the activity ===
# Are square, rectangle and rhombus parallelograms ?
# What are parallelograms ?
# How many pairs of parallel lines does a parallelogram have
# Is kite a parallelogram ?
