To help students adjust to the idea of “state”, it is helpful to use a tool like http://pythontutor.com or the whiteboard to have the values that are currently stored in a variable on display at all times. In doing so, a student will be less likely to misinterpret how a line of code will execute and may provide opportunities for students to ask more questions about why a program behaves in the way that they see on the screen or on the board.
