Tangrams

Learners construct tangram pieces. Then they make observations and explore patterns with the pieces.

Challenge the spatial thinking of your young mathematicians with this printable tangram puzzle. Using different sized triangles, squares, and parallelograms, children must figure out how to fit all the shapes together to create a square.

Students practice geometric and spatial principles through the creation of a tangram puzzle. They describe and identify shapes by folding them into the pieces necessary to complete a tangram. Students attempt to assemble their tangrams...

Students investigate the concept of creating different shapes using tangram pieces. They determine a number of combinations that can be used to create different shapes. Each student creates their own set of tangram shapes by cutting them...

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 what they discover to...

Primary geometers create a picture using tangrams. In this geometry lesson, learners read Grandfather Tang: A Tale Told with Tangrams, cut out their own tangrams, and choose a character from the story to make using their tangram pieces.

Students explore tangrams. For this tangrams lesson, students read Three Pigs, One Wolf, and Seven Magic Shapes and then complete a WebQuest on tangrams. Students explore shapes and rotation during the WebQuest and create a new character...

The second half of a two-part study of tangrams introduces first graders to geometry. A tangram template and many ideas are useful for a primary grade lesson in flipping and rotating shapes, and using geometric shapes to create other...

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

Students use the Internet to learn about transformations and tessellations.  In this geometry lesson plan, students use the Internet to define the meaning of reflections, translations, rotations, glide reflection and symmetry.  Students...
