👩‍🏫 Teacher’s Guide

Objective
Students will apply instructions for a sorting machine using the examples and practice below.

Vocabulary
instruction, input

Teaching Notes

• Model one response, then ask students to work independently and explain their choices with specific words or evidence.
• Teach the rule, discuss the worked example, and cover answers during practice.
• Use incorrect responses to identify which part of the rule needs another example.
• Allow approximately 25–35 minutes, including discussion and independent practice.

Read

Imagine a machine that sorts cards. It follows this rule: put red cards in Box A and blue cards in Box B. A green card arrives. The rule does not tell the machine what to do with it.

A complete set of instructions needs a way to handle unexpected input. The designer adds a third rule: put all other colors in Box C. Testing a red, blue, and green card checks three possible paths through the instructions. It is better to discover a missing rule during a test than after many cards have been sorted.

Rules can overlap or leave gaps. Suppose another instruction says that all large cards go into Box B. A large red card now matches two instructions. The designer must specify which rule takes priority or redesign the categories. Clear procedures make decisions repeatable, but only within the cases those procedures address.
