Beyond the Real Line: How AI Turned a Word Question into a Complex-Number Map

Expired

Complex Numbers: Extending the Number System develops Extension of the number system from real numbers to complex numbers through six visual, misconception-first stages.

Instead of presenting i as a rule to memorise, the activity makes the historical extension from natural numbers to complex numbers visible as a connected system. Learners move between number sets, algebraic notation and coordinates before they are asked to generalise.

Making Complex Arithmetic Visible: An AI-Built Vector Lab

Expired

Complex Arithmetic Vector Lab develops Four operations of complex numbers through six visual, misconception-first stages.

Addition, subtraction, multiplication and division are coordinated across symbolic steps and the Argand plane. The visual model lets learners see when an operation is component-wise, when multiplication mixes components, and why division needs a conjugate.

Equality as Evidence: An AI Component Comparator for Complex Numbers

Expired

Complex Equality Component Balance develops Equality of complex numbers through six visual, misconception-first stages.

The activity turns equality from a procedural statement into a two-channel comparison: real parts must match and imaginary parts must match. Learners see exactly which component fails and receive targeted remediation instead of a generic incorrect message.
