About the Lesson

Students write a small program to convert a sequence of decimal numbers into binary. The initial number set is chosen so that students can see the repeated ‘carrying’ through each column in the same way that decimal numbers ‘carry’. Students then work through some simple questions and then see how the ASCII system is used for communications and how well it ties in with binary numbers.
