Summary - Out now!

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 with fractions is developed.  Simplifying ratio, dividing in a given ratio and solving ratio problems in context are explored using procedural variation to support 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 component on scale factors and maps where the fluency of the earlier ratio work supports this application of ratio in a real-life context.

Starters are designed to encourage the independent retrieval of pre-requisite knowledge, requiring students to think rather than just be told, again.

Love your books!  We have given our GCSE cohort copies of J277 textbook AND the ClearRevise books. Hopefully we will do the same with Python Challenge books.
