TABLETS OF STONE You need to be in groups of 2 to 3 (no groups of 4) Only 10 groups are allowed) The groups will be numbered 0 to 9 (10 groups) You have a tablet and need to send a message to another group One of your group need to get up and walk to the other groups location so ensure the other group is a distance away, either: On the other side of the room and some distance from your group At the other end of the room

Make a message with 11 to 15 characters long including blank spaces and punctuation Example Pigs eat eggs. Say ‘Highway’. You have to develop a way (a protocol) of sending this message to the other group using packages/tablets (Tables of stones). Share this protocol with the other group once the protocol is created. A package/tablet of stone is a piece of paper with 6 square on it. Each square can only hold 1 character (a letter, number, symbol or blank space) You need to design a protocol that allows the packages/tablets to let the other group know: What your group number is (who sent the message). What their group number is (who is receiving the message). How many package/tablet are going to be sent.

You could use the numbering system 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d… where 0 is the 1st message, a is the 11th, b the 12th. etc. What this package/tablet number is (Is it the 1st, the 3rd, the 10th, the last, etc.) What the message (part message/information) is. Some mechanism for the other group to let your group know if a package/tablet has not arrived and needs resending. When you have designed this protocol share this protocol with the other group. Start delivering the other group your message using the packages/tablets of stone. You may find that you can only send one letter, number, symbol or blank space from your message per tablet/package. Send one package/tablet at a time (someone in your group will carry a package/tablet to the other group then return, get a second package/tablet and carry this to the other group, return and repeat this until all the packages/tablets that are going to be sent have been sent). Mix the order of the packages/tablets up before sending them. Ensure two of the packages/tablets are not sent which will create a fault to see if the other group can get the missing packages/tablets resent. Deliver at least one package/tablet twice.

Deliver at least one package/tablet to another random group. Ensure you know what is on each package/tablet so you can resend the package/tablet if requested.
