Area of Tangram Pieces

Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this instructional activity. They make a set of tangrams and use them to compute area. They use what they discover to work out formulas for finding the area of different geometric shapes and complete an assessment.
