Here are a couple of resources I came across from the web looking for resources on parallel lines. The first is perhaps more complex/less ‘fun’, the second maybe for younger? Going to try the first one tomorrow – I came across it on twitter, from geomchat (http://pbs.twimg.com/media/CSQd_vfW0AAjqhH.png) The second was a TES resource – thanks. Further ones added later below…

Michael Fenton was working on a parallel lines/perpendicular lines Desmos activity that looked quite good on his blog, but didn’t appear to be finished/published yet? Might be able to contact him to explore?

 

To really get them thinking a bit further, how about this image and question posed around curly parallel lines!
