This is something I produced for my top set Year 11s to cover the new GCSE topic of gradients of curves and area under graphs. Included is a PPT that covers several lessons building from general principles, through velocity-time graphs, to gradients of curves and area underneath them. Also included are examples to match the PPT that can be handed to students for annotation and worksheets for each lesson. The velocity-time graph worksheet is an adaptation of one sent to me so not sure of the original author but happy to credit if told. It all finishes with some exam style questions I've written based on sample assessment material from Edexcel.
