• Rectangles: opposite sides equal, four right angles, opposite sides
parallel;
• Parallelograms: opposite sides equal, opposite angles equal, opposite
sides parallel.
Materials:

The Greedy Triangle Written by: Marilyn Burns
Tangrams (the Super Source)
TEACHING PROCEDURE
Focus: (5M)
After starting the lesson by greeting the student and asking them about the
date and the day, the teacher will read a story (The Greedy Triangle) about
shapes. Reading this story contributes to children's learning by presenting
shapes in a combination of real-world and imaginary contexts. The story
invites children to wonder about what happens to shapes as they get more
angles and introduces children to the names of polygons and their properties
with posted some pictures of polygons on the board. After reading the story
and talking about the polygons in general the teacher will choose from the
board the three polygons that student will be taught this day (square,
rectangles, and parallelogram). Teacher will mention the objective after
focusing on the lesson.
Teacher Strategies (5M):
Reading the story and explain the shapes properties and stated the shapes in the
story on the board then stated the three shapes teacher will teach (square,
rectangles, and parallelogram). Then teacher will say: today we will study simple
side and angle properties of: squares, rectangles, and parallelograms. Ask
students to do a square using the tangram and ask them to explain how do they
do it and why. Then let students work as a group to reach a conclusion for the
properties of these shapes (square, rectangles, and parallelogram) according to
their sides and angles.
Student Activities:
The first activity: (5M).
Ask students to do a square using the tangram.
The second activity: (5M).
This will be a group work which will be an exercise to measure the sides and
angles for (square, rectangles, and parallelogram). Each group will have one of
these shapes to measure then to reach a conclusion for the properties of these
shapes.
Modifications / Differentiation: (5M)
For student with slower progress teacher will model how to measure shapes
and help them to reach the conclusion.
Lesson Extension: (5M)
Ask students to draw the three polygons (square, rectangles, and parallelogram)
using a dotted plate and a rubber.
Closure: (5M).
Restate the properties of each shape and restate the similarity and differences
between them.
Assessment:
As a home work student will search in magazine or internet for a pictures of
objects contains (square, rectangles, and parallelogram).
