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.
In how many ways can you stack these rods, following the rules?
How many different ways can you find of fitting five hexagons
together? How will you know you have found all the ways?
Can you recreate this Indian screen pattern? Can you make up
similar patterns of your own?
This practical activity challenges you to create symmetrical
designs by cutting a square into strips.
Can you see which tile is the odd one out in this design? Using the
basic tile, can you make a repeating pattern to decorate our wall?
What is the missing symbol? Can you decode this in a similar way?
Can you place the blocks so that you see the relection in the picture?
Where can you put the mirror across the square so that you can still "see" the whole square? How many different positions are possible?
Numbers arranged in a square but some exceptional spatial awareness probably needed.
How will you decide which way of flipping over and/or turning the grid will give you the highest total?
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?
