This activity investigates how you might make squares and pentominoes from Polydron.
Find the missing coordinates which will form these eight

with rotational and line symmetry.
Systematically explore the range of symmetric designs that can be
created by shading parts of the motif below. Use normal square
lattice paper to record your results.
This is the semaphore alphabet:
