Tangrams

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.

Challenge your class to construct a definition for trapezoids. Looking at four examples and four non-examples, students individually create definitions and use them to classify an unknown shape. Allow for small group and whole-class...

Budding artists or mathematicians read about,and then draw, two very different shapes. Geometric and organic 2-D shapes are defined. Learners use the definitions to draw examples of each.

Investigate the attributes of polygons. A thorough set of lessons presents problem scenarios for elementary through high school classes. The first lessons focus on basic characteristics of polygons, including the line of symmetry. As the...

Students explore tangrams. In 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...

Primary geometers create a picture using tangrams. In this geometry lesson, students 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 characteristics of shapes by making and using tangram sets. They discover how the tangram pieces are related to one another, and determine how many different combinations of the triangles, squares, and parallelograms in...

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

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

Students 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 worksheets are...
