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.

This amazingly extensive unit covers a wealth of geometric ground, ranging from constructions to angle properties, triangle theorems, rigid transformations, and fundamentals of formal proofs.  Each of the almost-forty lessons...

Students explore patterns involving objects or figures and geometric shapes. They identify the missing shapes in patterns and discuss what would come next in the pattern, analyze patterns using different objects, and complete a...

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

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.

The generation of a number, or shape pattern, is the focus of this math instructional activity. Pupils are presented with a variety of patterns shapes, and number patterns, then use worksheets embedded in the plan to gain further...

This interactive Learn Alberta math resource offers a hands-on exploration of number patterns. Students get to control an animated squirrel in order to figure out terms in a sequence and see each pattern represented both in picture form,...

This multimedia Learn Alberta math resource provides students with a video clearly demonstrating the use of patterns to develop choreography for dance routines. Be sure to follow the link to the provided interactive exercise that offers...
