you dont
It's not possible!
It depends on the shape of the six pieces.
use triangles as eyes with the point upward
It is to hard for kids in 4th grade and other grades
You take one of the large triangles and then put the square on the side of the triangle on the top towards the verticy. Then put the smaller triangle under the square and put the parallelogram under that so it all lines up.
Without the triangles of a tangram all that is left is the parallelogram and the small square. So using only the small square yes (the small square itself), otherwise with the square and the parallelogram from a tangram no.
no because it has to be all equal and right angles
