FM L1.17 Work with simple ratio and direct proportions

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.

A colourful card matching task in which students interpret practical scenarios involving proportional relationships in terms of ratios and the total numbers of equal parts involved in them.

In pairs, they move the cards/ paper slips around and discuss how to match four ratios (white) with the four statements about parts (blue) and the four practical situations and actual amounts which correspond with them (yellow).
