Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this lesson. They make a set of tangrams and use them to compute area. They use...

In this tangram worksheet, learners find the area of each tangram shape. Afterwards, they name each piece and find the area of combined figures. This one-page worksheet contains approximately 25 problems.

Young scholars explore "area."  In this tangram geometry and measurement lesson, students arrange tangram pieces to find the area of characters presented in a story they listen to on a website.  Website information and related...

Tenth graders connect the history of geometry to problem solving. In this geometry lesson, 10th graders investigate polygons through hands on manipulatives and solve problems relating to parallelograms and triangles. They calculate the...

Students explore the origin of tangram. In this algebra lesson, students form different shapes and figures using tangram. They solve for the area of different shapes without using any geometric formulas, but the idea of tangram being put...

An ancient puzzle game meets a modern implementation. Challenge mathematicians of all ages with this mind-bending geometric puzzle game. 

Seventh graders explore area and perimeter, using tangram pieces. They discover the area and perimeter of rectangles and squares. After experimentation, 7th graders write a rule for finding the perimeter and area of squares and rectangles.

Explore the world of shapes! After free tangram exploration and pair share time, learners describe various patterns and shapes in both the natural and designed world. They investigate the use of tangrams to create patterns and shapes.

Students listen to a story involving Tangram pieces. Students use Tangram pieces to complete shapes using an outline of a design.

Students research the history of Chinese tangrams and complete tangram activities. In this tangram lesson, students complete Internet research to learn the history of Chinese tangrams. Students construct a set of tangrams, compare the...

Seventh graders visualize and identify geometric shapes after applying transformations on a coordinate plane. In this tangrams lesson, 7th graders construct a set of tangrams and then answer extension questions related to measurement,...

Students use tangrams, student literature, and Websites to explore shapes.

This resource guides young geometers to create new polygons from others of equal area, compare an image to its reflection and find errors, conduct repeated reflections, map translations, and determine center of rotation. No solutions are...

Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.

Students follow written directions to construct their own tangram. In this tangram lesson, students use their tangram to develop original figures that illustrate characters and/or objects from their favorite nursery rhyme. Students also...

Students explore two-dimensional and solid shapes. In this shapes and patterns geometry lesson, students work with a partner to create identifiable objects using tangrams. Students describe the attributes of their shape and their partner...

In this geometry worksheet, students choose the multiple choice answer to 15 questions involving several different elements of geometry.

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

Students assign numbers to describe objects. In this number lesson, students assign numbers to objects and compare more, less, and equal values. They write down descriptions of plants including the number of leaves and height of the...

Kindergartners listen to a story read by their teacher, then use magnetic shape pieces to construct simple designes. They "build" their own house using pre-cut paper shapes. This age-appropriate lesson would be an excellent choice for...

Shapes are so fun! Little ones explore, identify, and create shapes using tangrams or pattern blocks. The activity is intended to stimulate critical thinking while engaging learners through play and shape identification. Each child will...

Third graders read Ann Tompert's book, Grandfather Tang's Story, and complete math word problems based on the story. For this word problems lesson plan, 3rd graders use tangrams in the word problems.

Learners create their own Chinese tangrams using in-class direction and prior knowledge in this two-day activity for the early elementary classroom. Chinese toys are also explored.

Geometric shapes are really cool. Examine triangles, quadrilaterals, trapezoids, rhombuses, parallelograms, pentagons, and hexagons with your class. They draw large shapes and small shapes then compare them to understand their shapely...
