Numbered Cards for Concrete Abstractions

This web page provides help making numbered cards for use with Concrete Abstractions: An Introduction to Computer Science Using Scheme, by Max Hailperin, Barbara Kaiser, and Karl Knight. These cards are used for comparing two different sorting algorithms. There are three options for making the cards:

Another option, if you can't tear yourself away from the computer to deal with physical cards, is to instead use the simulation of card sorting which we provide as a Java applet (your web browser must support Java 1.1). Our preference is for the real cards, but the "virtual manipulative" is better than nothing.
