Nicole Cunningham
Author
Nicole Cunningham is a passionate educator with five years of experience and is currently teaching at a school for learners with visual impairments. Her work in special needs education has taught her the importance of adhering closely to CAPS – every lesson must be purposeful, precise, and accessible.
During her Master’s in Mathematics Education at the University of Pretoria, Nicole developed a strong interest in inquiry-based learning. She was surprised to see how well CAPS supports this approach, yet how few teachers know how to implement it effectively or create meaningful CAPS-aligned learning material.
Nicole is committed to bridging that gap by developing resources that are curriculum-driven, engaging, and inclusive for learners.
