# Often asked: What Is A Tangram In Math?

## 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 do you make a tangram in math?

Cut out your square. At this point, you could stick the square onto card and cut it out again. This may make your tangram a bit stronger. Cut along the lines you’ve drawn so that you now have three pieces which fit together to make the original square.

## What is the purpose of a tangram?

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.

## How do you solve a tangram?

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 are the 7 shapes in a tangram?

The Tangram is a deceptively simple set of seven geometric shapes made up of five triangles (two small triangles, one medium triangle, and two large triangles ), a square, and a parallelogram. When the pieces are arranged together they suggest an amazing variety of forms, embodying many numerical and geometric concepts.

## Why do tangram pieces need to all be polygons?

TANGRAMS AS POLYGONS Since proper tangrams consist of the seven tans touching without overlapping, then YES, tangrams are polygons. Polygons, can be simple or complex. A simple polygon is an enclosed shape consisting of straight, non-intersecting lines.

## Who invented Tangram?

Tangram puzzles originated in Imperial China during the Tang Dynasty, they are thought to have travelled to Europe in the 19th century on trading ships. Tangram puzzles were popular during World War 1 and have become the most popular dissection puzzle in the world.

## Are tangrams and pattern blocks the same?

TANGRAMS are geometric puzzles that include 2 large triangles, 1 medium triangle, 2 small triangles, 1 square, and 1 parallelogram. Often these students benefit from pattern blocks and simpler activities before advancing to tangrams. PENTOMINOES are 12-piece puzzles that are scored in 1-inch sections.

## How are Tangram used in the classroom?

There are many ways that the tangram can be used in the class. The seven tans can be used to make various geometrical shapes. Divide the class into groups of four and let each group make a set of tangram pieces. Check if all groups have the seven pieces of tans.

## How many types of tangrams are there?
