Age-based learning path
Move from patterns to rules you can test.
Learners can connect computational thinking to systems that use data and logic. Work with binary place values, write clear algorithms, and test how gate outputs change when inputs change.

A progression to explore
Build a concept in three passes.
Predict
Use a truth table to predict an AND, OR, or NOT gate output.
Test
Change one input at a time in the Logic Lab and compare it with your prediction.
Explain
Describe the rule behind the result using a short sentence or diagram.
Challenge
Can you make a gate from other gates?
Try constructing an XOR rule using NOT, AND, and OR operations. First write the truth table, then sketch the connections.
Think it through
If exactly one input is 1, the output is 1. If both inputs match, the output is 0. What sequence of simple operations would create that behavior?
Beyond the gate
Ask what the representation leaves out.
Digital systems use representations to store and process information. A representation is useful because it follows shared rules, but it also shapes what can be expressed easily and what context may be lost.
