I don't know. Assuming you don't have to deal with setup issues (the machines are ready to go), you should be able to present IO, variables, assignment, arithmetic operations, IF statements, and loops. Then give them a program that reads and repeats numbers, and ask them to modify it to print out the biggest number and the average. You'll have to move fast and just skim the surface of everything, but that would get them to programming within two hours.
