Highly structured worksheet, initially created for a low ability year 8 class, on finding the angle sums of various polygons by splitting the shape into triangles.
I often extend students by asking them to look for the connection between the number of sides the shape has and the number of triangles we split it into before introducing the formula.
Something went wrong, please try again later.
Thank you, this is lovely - I like the use of the box at the top to show how to complete it. Might be nice to include quadrilateral as well, so they can see it works for those, rather than them being separated. But really great, thank you so much for sharing.
