This is a fantastic lesson on introducing trig graphs by using spaghetti to draw them... it sounds a little wacky, but it is an incredibly effective way of building understanding before looking at more challenging aspects. It is a foundational lesson that long-term pays dividends! 12 slides + resources.
The lesson comes with a starter, all the instructions needed, an exemplary answer, examples and plenary. This lesson does come as a part of a large series/ bundle teaching the various aspects of trig, and there are three further lessons on trig graphs that follow on from this one. They are all excellent and I do highly recommend getting them as a series together as the lesson build on each other.
