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.

What people say...

I love the way you guys work!

Mr I Cooper. Teacher of Computing, Academy 360

I am really pleased with the resources for the Unit 8 'Crude Oil and Fuels' so far. As I am non-specialist teaching the new specification of AQA GCSE Chemistry for the first time this year, these resources have been invaluable to me. The presentations are thorough and well illustrated. The teacher guide and power point presentation leads you through the topics logically. This has been particularly useful as I have been tasked with picking up this course with students that are already midway through their GCSE and the commentary has provided me with useful guidance of what students should have covered in earlier modules and there are also activities that recap earlier learning. The fact that the resources are so thorough and there is a WS and HWK for every lesson, has saved me a huge amount of planning time as there is already plenty for students to do. All I have had to do is add a little further differentiated practice as and when my students needed it. I will definitely be looking at buying other modules too.
