Tangram

Tangram is a squared puzzle consisting of seven flat polygons. It can help children learn geometric shapes, develop problem solving abilities and enhance creativity. Now, let's make a tangram, solve as many puzzles as you can and share them with others! Have fun!

Also, why not making a 3-dimentioanal tangram? It can help children learn 3-dimentional shapes and develop sense of space and orientation. Enjoy!

Remark: Brief information about tangram is in step 4.

• 1 piece of squared construction paper / origami paper
• a carton
• corrugated cardboard
• a pair of scissors
• 1 glue stick / white glue
• a pencil and a ruler

Follow step A to D, fold in the dotted lines and make creases.

Referring to the picture, use a pencil and a ruler to draw seven different shapes on the paper.

Stick the paper to the carton with glue stick / white glue. When it is dried, cut out the shapes along the line.

Each tangram puzzle contains seven shapes, they are:

• 2 large right triangles
• 1 medium right triangle
• 2 small right triangles
• 1 square
• 1 parallelogram

In this activity, it is recommended to guide children to discover the relationship between the side and area of each shape.

Here are some examples. Solve them and create your own tangram puzzles. Have fun!

Repeat the above steps 1 and 2, stick the paper to the cardboard with glue. When it is dried, cut out the shapes along the line.

Use a pencil to draw the shapes on the cardboard and cut them out. Repeat this step and make more 4 sets of tangram. Then, stick the shapes together with glue as shown in the picture to make the shapes thicker.

Here are some examples. Create your own 3D tangram puzzles. Have fun!
