Outline
The session will involve investigating some
fruitful mathematical Involving the use of
multilink cubes. We will work on problems and
environments available on the NRICH website and
will examine their potential to meet the needs
of a range of curriculum contexts. We will look
in detail at two or three examples based
on Tiling isosceles and equilateral
triangles Properties of cubes

Triominoes

• Can you imagine all the Triominoes?
• For each Triomino can you tile any square?

Triominoes (Oct 2000)
A triomino is a flat L shape made from 3 square
tiles.                                  A
chess board is marked into squares the same size
as the tiles and just one square, anywhere on the
board, is coloured red. The aim is to cover the
board with trionimoes, not overlapping, so that
only the red square, wherever it is, is exposed.
Is this possible? Investigate. Explain.

Tetrominoes

• How many 2-D tetrominoes are there?
• How do you know you have them all?
• Do you have a strategy?
• Convince me.
• What about 3-D tetronimoes?
