Introduction

Tangram puzzles are very popular. This one consists of 7 parts which, when put together, form a perfect square.

Materials

Foam board or scraps of foam board. The board is available for $1.00 at Dollar Stores. The paper covering the board may be left on or removed.

Carton sealing tape. Available in a variety of colors. I purchased mine from Amazon.

Plain paper for template.

Sand paper - fine.

Tools

Marker

Ruler

Xacto knife

Scissors (optional)

Sanding block.

Step 1: Create the Template

Draw a square 2.83" x 2.83"

Inside the square form the following pieces (see image).

2 large right triangles (2.83" x 2" x 2")

1 medium right triangle (2" x 1.41" x 1.41")

2 small right triangles (1" x 1" x 1.41")

1 square (1" x 1")

1 parallelogram (1" x 1.41" x 1" x 1.41")

Completed template may be enlarged or reduced in size.

Step 2: Cut Out Template Pieces

Use Xacto knife or scissors to cut out template pieces.

Position pieces on top of foam board. These may be placed, glued, or taped onto the foam board.

Use the Xacto knife to cut the foam board.

Sand the edges of each piece for comfort (removes sharp edges) and visual appeal.

Wrap carton sealing tape around each piece to ensure that each piece lasts a long time.

Put the Tangram pieces together form a perfect square. I have laid the paper template on top so that you can clearly see the solution.
