## games and investigations

I love dominoes. No, not the pizza, but the little things with dots on. There are lots of mathematical games you can play with them, some of which are here.

I particularly like threes and fives; I have also played a version where you get points for

You could play a game where students lay them vertically or horizontally on a mxn grid.... the winner is the last one to lay a domino.

If the dots were raised on a domino, could they be used as letters for Braille? If so, why? Which ones would you use for which letter?

Here's an idea for some investigations by considering them as 2 by 1 'bricks': How many different ways can you arrange them to fill a box (say) 2x4 wide? mxn wide?

How many different tessellations (brick walls) can you make with dominoes? Which ones would make better brick walls than others, and why?
