===Learning objectives===
 
===Learning objectives===
 +
# A 4-sided flat shape with straight sides where opposite sides are parallel.
 +
# Also opposite sides are equal in length, and opposite angles are equal.
 +
# Squares, Rectangles and Rhombuses are all Parallelograms.
 +
# Properties of a parallelogram are :
 +
a. Opposite sides parallel<br>
 +
b. Opposite sides equal<br>
 +
c. Diagonals bisect each other<br>
 +
d. Opposite angles congruent<br>
 +
e. Consecutive angles supplementary.

*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 ?
