## What is called Tangram?

Invented in China approximately 200 years ago, a tangram is a two-dimensional re-arrangement puzzle created by cutting a square into seven pieces — seven geometric shapes called “tans” (Slocum et al 2003). Each tangram puzzle contains the following: 2 large right triangles.

## How are tangrams used in math?

Tangrams help students at the middle grades develop spatial-visualization skills and introduce or reinforce geometric concepts such as congruence, similarity, symmetry, etc. Students use them to compute the area of polygons, or Tangrams can be used to introduce the terms “congruent” and “similar.”

## How do you solve tangrams?

Tangram Rules and How to Play Tangram

1. The pieces must all be connected.
2. They must be flat.
3. No pieces may overlap.
4. The tans may also be rotated and/or flipped to form the shape.
5. All seven tans must be used.
6. Each completed puzzle must contain all seven tans.

## What does a tangram look like?

Lesson Summary A tangram is a puzzle that has two big triangles, one medium triangle, two small triangles, one square, and one parallelogram. The aim is to fit all of the seven pieces inside of a given outline without shapes overlapping, going outside of the outline, or leaving blank space inside.
