There are 35 distinct hexominoes. You will need patience and

systematic thinking to find all of them.

1. Make drawings of all 12 pentominoes. (avoid duplicates)2. Eight of the pentominoes can be folded to make an “open-top”

box. Draw and shade the base (bottom) of the ones that can.3. Draw the pentominoes that have line/reflective symmetry and

draw the lines on them.4. Draw the pentominoes that have turn/rotational symmetry and

write down the order of this symmetry in each case.5. All pentominoes have the same area but do they all have the

same perimeter? Investigate and provide examples.6. What is the total area of all 12 pentominoes?7. Make a list of all possible rectangles (l x w) that could be made

from this area.
