Tangrams help develop spatial-visualization skills, and may also be used to introduce or reinforce geometric concepts such as congruency, similarity, and symmetry. This unit for grades 4-6 uses tangrams to find the areas of polygons without employing formulas. Students construct their own tangrams, find the areas, and learn to calculate the area of any polygon made from tangrams.

The Math Forum is committed to being a resource built upon the activity of the teachers, students, and researchers who use it. We continue to experiment with the use of the Web for instruction and with involving Forum users in the creation of materials for this enormous Internet classroom. Teacher Tom Scavo's Tangrams unit is one example; you will find links to others on our Web Units page:
