golden ratio

Devised for L1 as a first lesson for ratio utilising practical applications for ratio understanding. Please print the last slide as a worksheet to accompany the PPT.

Editor's notes

Introductory example using a KitKat bar, followed by other everyday applications including screen wash, hair tint and paints.  Also (very nicely) covers equality & diversity with discussion about the proportion of White British players in the 2018 England squad.
