This activity investigates how you might make squares and pentominoes from Polydron.
Find the missing coordinates which will form these eight
quadrilaterals. These coordinates themselves will then form a shape
with rotational and line symmetry.
What is the missing symbol? Can you decode this in a similar way?
Systematically explore the range of symmetric
designs that can be created by shading whole squares of the grid
Use could use this sheet of blank
grids to record your results, or simply squared paper.
How many can you find?
