Plex lets you specify a mapping between points and their images.
Then you can draw and see the transformed image.
Create a pattern on the left-hand grid. How could you extend your pattern on the right-hand grid?
These images are taken from the Topkapi Palace in Istanbul, Turkey.
Can you work out the basic unit that makes up each pattern? Can you
continue the pattern? Can you see any similarities and. . . .
What is the relationship between these first two shapes? Which
shape relates to the third one in the same way? Can you explain
This article describes the scope for practical exploration of tessellations both in and out of the classroom. It seems a golden opportunity to link art with maths, allowing the creative side of your. . . .
A shape and space game for 2,3 or 4 players. Be the last person to be able to place a pentomino piece on the playing board. Play with card, or on the computer.
Use the blue spot to help you move the yellow spot from one star to

What are the coordinates of this shape after it has been
transformed in the ways described? Compare these with the original
coordinates. What do you notice about the numbers?
How will you decide which way of flipping over and/or turning the grid will give you the highest total?
Numbers arranged in a square but some exceptional spatial awareness probably needed.
Overlaying pentominoes can produce some effective patterns. Why not
use LOGO to try out some of the ideas suggested here?
