Teachers, save “Crack the Code” to assign it to your class.

All computer data is represented using binary, think images, numbers, letters, etc. Binary uses a system that uses only 1's and 0's (on/off). Binary digits (a bit) can be grouped together in a set of 8 to form a byte. Using your knowledge of binary code, look at the images and write the binary code for each in the text box. The first line has been completed for you. Hint: 1=on, 0=off
