By – Carolyn Currins
Primary Subject – Math
Secondary Subjects – Language Arts
Grade Level – 4th Grade


Lesson 1: Creating Tangrams

Objective: To introduce students to tangrams and allow them an opportunity to explore their characteristics.

Grade Level: 4

Materials:

  • 8 ½ x 11 piece of construction paper for each student
  • Plastic sets of Tangram pieces for each student
  • Overhead set of Tangram pieces
  • Scissors

    Procedures:

    • TTW (The teacher will) explain to the students that a tangram is an ancient Chinese puzzle.
    • TTW explain that the pieces of a tangram puzzle form a square from seven pieces.
    • TTW tell the students that they will be making their own set of tangram pieces using just one piece of construction paper.
    • TTW pass out a piece of construction paper, scissors and directions on how to make the tangram pieces to each student.
    • TTW guide students through the process of creating their own tangram pieces.
    • TLW (The learner will) follow the instructions as the teacher reads them and create seven tangram pieces.
    • After the students have created their own tangrams, TTW ask the students to get into pairs.
    • TTW pass out a set of plastic tangram pieces to each pair and ask them to compare the pieces they made to the plastic set.
    • TTW be able to tell if the students followed directions by watching how the students’ shapes compare to the plastic tangram pieces.
    • TTW then give the students a few minutes to explore with the plastic tangram pieces on their own and listen to conversations that students have about the pieces (attributes, sizes, etc.).

    Assessment/Evaluation:

    • TTW check to see that students followed directions by observing how their paper pieces compare to the plastic tangram pieces.
    • TTW monitor students’ conversations about their observations of the tangram pieces.

    Lesson 2: Exploring Tangrams

    Objective: To provide students with some insight as to how the tangram pieces fit together, and to stimulate their interest in forming shapes using the tangram pieces.

    Grade Level: 4

    Materials:

  • Set of tangrams for each student
  • Construction Paper
  • Pencil

    Procedures:

  • TTW review with the students about what was previously observed about the tangram pieces.
  • TLW describe the pieces of the tangram square.
  • TTW ask the students to get into pairs and pass out a set of tangram pieces to each pair.
  • TTW guide the students in a sorting activity using the seven shapes.
  • TTW ask the students to sort the pieces by the number of sides.
  • TLW sort the pieces into two piles — one pile with pieces that have 3 sides, one pile with pieces that have 4 sides.
  • TLW identify the shapes with three sides as triangles, and the pieces with four sides as a square and a parallelogram.
  • TTW ask the students to sort the pieces by their shape.
  • TLW sort the pieces into piles by triangles, square, and parallelogram. If some students put the square and parallelogram together TTW ask the students to explain why (Some students may remember that a square is a parallelogram).
  • TTW guide the students in an activity that will allow the students to create other shapes using their tangram pieces.
    • TTW ask the students to create a triangle using 2 shapes.
    • TTW ask the students to create a triangle using 4 shapes.
    • TTW ask the students to create a square using 2 shapes.
    • TTW ask the students to create a square using 4 shapes.
    • TTW ask the students to create a rectangle using 3 shapes.
  • TTW have the students create the shapes on a piece of paper, outline the shape, label it, and state which tangram pieces were used.
  • TTW collect their papers when all students have completed the activity.
    Assessment/Evaluation:
  • TTW monitor students’ conversations about their observations of the tangram pieces.
  • TTW ask the students to sort their shapes using various attributes and will walk around the room to check for understanding.
  • TTW collect outlines of the shapes students created.

    Lesson 3: Manipulating Tangrams

    Objective: The students will use problem solving to manipulate tangrams and recreate animals from Grandfather Tang’s Story .

    Grade Level: 4

    Materials:

  • Grandfather Tang’s Story By Ann Tompert
  • Student-made Tangram pieces
  • Outlines of pictures from Grandfather Tang’s Story to be duplicated using set of Tangrams
  • Overhead Projector
  • Overhead set of Tangram pieces
  • Overhead copies of outlines from Grandfather Tang’s Story

    Procedures:

  • TTW review with the students the history of Tangrams.
  • TTW separate the students into pairs and give each pair two shapes to recreate using their set of tangrams.
  • TLW attempt to recreate each shape using their homemade tangram set.
  • TTW monitor progress by walking around the classroom and listening to dialogue between students.
  • TTW assess the completion of the pictures by asking students to recreate the picture on the overhead in front of the class.
  • TTW read Grandfather Tang’s Story to the class.
  • TTW place the students into pairs and give each pair a picture of an animal from the story.
  • TLW recreate the animal using their homemade set of tangrams. After completion of the picture, TLW glue the paper pieces on a piece of construction paper.
  • TTW reread the story asking each pair to hold up their version of the animal when it is mentioned in the story.

    Assessment/Evaluation:

  • TTW monitor progress of the students’ ability to manipulate the seven shapes of Tangram Square to create other larger shapes.
  • TTW check for correct completion of the various shapes from Grandfather Tang’s Story by evaluating the animal each pair recreated using the paper tangrams.
