With a strong emphasis on using techniques from bar modelling to develop mastery, this unit focuses on developing skills with ratio. Starting from the basics, the concept of ratio, its notation and the connection to fractions is developed. Simplifying ratio, dividing in a given ratio and solving ratio problems in context are explored and procedural variation is used to support this learning. Direct proportion is linked to ratio and students recognise, represent and use direct proportion to solve graded questions. Ratio as a linear function is presented graphically, and students interpret the gradient and use reasoning to solve questions in context. The unit closes with a lesson on scale factors and maps where the fluency of the earlier ratio work supports this application of ratio in a real-life context.
