You can use the digital binary cards above, or work it out manually.

Task 1.5

Create your own message

Use any symbol, colour, or physical object that can exist in two different forms or states to create a poster in Binary to spell out Your Name or Greeting or Phrase.

For an extra challenge can you use a symbol, colour, or physical object that relates to your choosen word/s

For example two different states could be things like: a coin (heads and tails), a switch (on and off), colour (blue and green), shapes (circle and square)

There are to be two slides:

Chess Board Riddle

There is an old Indian legend about a King who was challenged to a game of chess by a visiting Sage. The King asked "what is the prize if you win?".

The Sage said he would simply like some grains of rice: one on the first square, 2 on the second, 4 on the third and so on, doubling on each square. The King was surprised by this humble request.

Well, the Sage won, so how many grains of rice should he receive?
