Pattern exploration is central to the process of inquiry in mathematics as well as a fundamental component of children’s mathematical growth. Within mathematics, a pattern is something that remains constant in a group of numbers, shapes or attributes of mathematical symbols. Number patterns — such as 10, 20, 30, 40 or patterns associated with counting — are some of the earliest patterns we learn to generate as children. What remains constant in these patterns is the difference between each successive term. The identification of pattern associated with the structure of numbers is important not only for developing flexibility with computation, but also in creating a foundation for algebraic thinking (i.e. thinking about generalised quantities).
