*Process/ Developmental Questions
*Process:
*Evaluation
# The teacher can use this geogebra file to introduce parallelograms to students.
*Question Corner
# She can move the vertices A or B or c and observe different parallelograms formed like square, rectangle and rhombus.
# Bring their attention to measures of sides, angles and diagnols.
*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:
# What are parallelograms ?
# Are square, rectangle and rhombus parallelograms ?
# How many pairs of parallel lines does a parallelogram have ?
*Question Corner:
# Are all parallelograms quadrilaterals ?
# Is kite a parallelogram ?
