Binary Magic Trick The binary magic trick is a set of 6 cards with numbers on them. you show the cards to someone and have them secretly choose a number and then select all of the cards that contain that number. using your magic powers, you can easily figure out which number they have chosen. the secret to this magic trick relies on knowledge of binary numbers. I've added documents for the binary magic trick activity that i use after introducing the students to binary numbers. this includes the cards (to cut out) and a set of instructions on how to perform the trick.
Binary Magic Trick E number. how does it work? this based on binary numbers: all of the numbers that have a 1 in the on. s place are on the "1" card. all of the numbers that have a 1 in the twos pl. ce are on the "2" card, etc. for instance the . umber 23 is 10111 in binary. the number 23 appears . The card flip magic trick helps to demonstrate how computers can detect errors in the binary data it sends and receives using parity checks. you can use regular playing card decks for this. What is computational thinking? used by computer scientists and magicians! the interesting parts are: algorithmic thinking decomposition abstraction and generalisation. The magic of computer science ii begins with an introduction to the resource, explaining the basic concepts used in the book. there follows descriptions of how to perform seven tricks with explanations of how the trick works and the computer science concepts illustrated in the tricks.

A complete presentation with all the visuals for introducing binary conversions. instructions written by a cs teacher who has performed magic for more than 40 years. the magic trick is fool proof and requires no special talents other than being able to add and subtract. Here we have some data in a 5 by 5 grid of cards. i'm going to make it more difficult for myself by adding another row and column to it. the information represented in this grid is 'binary data' because it uses two values (black and white) to represent information. Binary magic answer here's how to do the trick: add up the number on the upper left corner of those cards that the audience answered "yes" to. for example: an audience member who is 20 years old would pick out the third and fifth cards, which are the only ones with "20" on them. To ensure that, when you send data over a computer network, all the data does make it to the other end without getting scrambled, computer scientists and engineers came up with the idea of adding parity bits to each block of data.
