Interacting With Mathematics in Key Stage Three

This collection of resource materials from the National Strategies focuses on important ideas and processes which underpin a sound understanding of mathematical thinking and reasoning in the key areas of proportional reasoning, linear equations, geometrical thinking and handling data.  Handling data is specific to Year Eight and is based on the Year Eight sample medium-term plans. The emphasis of the Year Nine Geometrical reasoning unit is on reasoning rather than content, much of which may be familiar to students. The approach allows greater rigour to be developed by re-establishing familiar definitions and properties into a logical hierarchy. Proportional Reasoning and Linear Equations track the progression of the ideas through the three years of Key Stage Three.
