Student strategies
These various strategies are to help you as parents identify the method in which your child might be solving their problems and give you some familiarity with the strategies to engage in conversation with your child about their strategy.
These strategies are not to be seen as a linear progression towards the standard algorithm. In fact, I would argue that the standard algorithm is not the most efficient strategy and by no means the end goal when working with students on building their understanding of the four operations.
The strategies below all have their place depending on the problem posed and it is important that students have opportunities to solve problems and choose which strategy to use as they develop efficient and flexible uses for these strategies.
