Lesson 13: Punch cards

This lesson focuses on abstract representation as a concept using code. Students will look closer at punch cards to see how holes can represent words or commands. The lesson gives a brief history of punch cards, which is followed by an activity that allows students to create their own punch card commands for more physical coding as a class. Previous lessons used pseudocode cards to “code” physically. Those index cards were closer to real program than one might think.
