2. TLW trace a circle on the left side of a sheet of construction paper using a circle template. Choose tangram shapes to fill the circle in a symmetric pattern inside the circle. Next to the picture write the names of the shapes used. Color the shapes using some type of color pattern that will add to the symmetry of the design.
