Lesson 3.5: Data Representation with Binary, Part 3
Learning Objectives:  Students will become even more comfortable with binary numbers.
 Students will explore more difficult binary concepts, such as what happens if a zero is added to the end of a binary number.
Do Now: Watch: Marble Adding Machine
In this video, we are adding numbers together and representing their sum in binary. This gives us a way to visualize what is happening when we add in binary. Try to answer these questions:  What happens if you add a marble (which represents a 1) to an empty slot (which represents a 0)?
 What happens when you add a marble (1) to a slot that already has a marble (1)? Where do each of the marbles go?
 What is the biggest number Miss FlexiToes can count up to using only her ten fingers and ten toes?
