tangram
Traditionally used to create shapes and figures from seven geometric pieces (or tans): five triangles in different sizes, one square, and one parallelogram. Tangrams can also be used for other math functions, including measures of area and fractional parts and wholes.

Tangrams
While reading Grandfather Tang's Story by Ann Tompert, students will be using tangrams to create the animals that the fox fairies are turning themselves into in this story.

Inside, outside, and all around
Students will distinguish between perimeter, area, and volume. They will use tangrams and graph paper to create two-dimensional figures that will be measured for area and perimeter. By creating layers of centimeter cubes, the students will explore the concept of volume.

Multicultural cross-grade level unit plan
This unit of study integrates reading, writing, math, and social studies. It is designed to help first and third grade students relate to other cultures of the world. They will understand and compare the similarities and differences of children, families, and communities in different times and places. They will analyze religious and other cultural traditions. They will apply basic geographic concepts.
