Resource title: Coordinate geometry cards

What is it?

AS-level students often find coordinate geometry tricky, which is odd given that they studied all of the basic skills at GCSE. But perhaps that's the problem... Because they already have an understanding, they don't give it the same level of concentration as they would something new. 

While the skills may be similar to those at GCSE (eg, finding gradients, midpoints etc.), the ability to apply them in a range of contexts is more difficult at AS-level. This lesson, made up of tasks and activities, enables students to fully appreciate the complexity of the topic in a challenging and engaging way.

How can it be used?

The lesson is really well-structured. The starter could come straight from a GCSE lesson and serves to remind students of the core skills they need to know and use. Following this, I suggest distributing the printed notes as a reminder ahead of the application.

For the main body of the lesson, why not divide the class into groups? Give pupils a counter to exchange for two minutes on a free online graphing calculator, such as Desmos. This enables students to visualise and manipulate coordinates and lines, making concepts less abstract. It's also incredibly useful as a visual aid when going through the answers.
