Notes are provided on the slides. You will need a copy of Martin Luther King's' I have a dream' speech. It can be downloaded from Youtube if necessary.

Sequence of slides showing things that are valued highly in monetary terms. Ask students to speculate as to the value of each object, before clicking to reveal the value. Finally, ask them to tell you what they value that doesn't cost anything. Did this with Year 7 and Year 8, but I suspect it would work OK with any year group.
