This paper argues for effective sequencing of mathematics content to aid transition from junior (Year 7 to Year 10) to senior mathematics (Year 11 to Year 12) curriculum in Queensland, Australia and provides a tool for sequencing the mathematics content. Planning templates and samples are available to schools; however, it is imperative for teachers to understand the processes that underpin planning. This paper provides a step-by-step systematic sequencing of mathematics concepts. The premise is that depending on the level of assumed prior knowledge and skills students recall and apply, teachers can start teaching from any level. The study draws from constructivism to develop a planning tool that can be adapted to all mathematics subjects and levels, help identify conceptual relationships and skills from lower to upper levels and provide students with the opportunity to build their mathematical knowledge.
