Time: 45 minutes
1. A tangram picture must use each tan.
Each tan must be touching, but not overlapping each other.
2. Many shapes can be joined together to form different sizes and forms
3. A practical use of tangrams is to use them to illustrate a story.
By the end of this lesson the student should be able to:
1. Know what a tangram is.
2. Know what shapes a tangram has.
3. Understand how to make larger, or different, shapes using tangram
4. Construct animal tangram pictures.

Ask students to review to the class what we learned
yesterday about tangrams.
Tell students that today we will be making pictures
out of tangrams.
Tangram pictures are made using every tan to
create a beautiful whole picture. The SCI principle I will be using
is: the whole is greater than the sum of the parts
To have fun with shapes, and to discover how
shapes fit together to make pictures.
1. I will read Grandfather Tang’s
2. As we read along one child will model the tangram picture from the
story with magnet tangrams.
3. While one student is working with the magnet tangram, the other children
will be sitting at their desks trying to create the picture with their
Compliment the group on their hard work and success
in making the tangram pictures. Ask the class what their favorite tangram
picture to make was.
Have the children summarize what we learned today
about tangrams and creating animal tangrams.
Tell students that they should take their paper
constructed tangrams home and see if they can make a tangram of the
animal that they’re each studying for their animal project. They
should try and trace around the tangram to create the picture on paper
(to share in class).
At the end of all the lessons on tangrams, I
would have each child demonstrate how the 7 pieces of the tangram fit
together into a square. I would also use pages from My first tangram
activity book to assess if the child can fit various shapes together
to create something new. I would also ask what observations the child
could make about any aspect of tangrams.
Skill 1 -- Can the child fit the shapes
together into a square (without help or reference)? Check/minus
Skill 2 -- The teacher selects 3 shapes from My first tangram activity
book. The child should accurately complete at least 2 of the shapes.
3 shapes --plus
2 shapes -- check
1 or less shapes -- minus
Skill 3 -- Can the child make any 2 observations about tangrams?
Clearly describes 2 observations about tangrams -- plus
Describes 2 observations about tangrams -- check
Describes 1 or no observations about tangrams -- minus
