Summary A strategy to facilitate understanding of spatial randomness is described, using student activities developed in sequence: looking at spatial patterns, simulating approximate spatial randomness using a grid of equally‐likely squares, using binomial probabilities for approximations and predictions and then comparing with given Poisson probabilities. Key questions are discussed with students on concepts needed to understand the approximate models and to generate predictions based on the approximations. The sequence is structured to be interactive to encourage student's interest and curiosity.
