Colour wheel lesson and plenary 'Justin Beibhair'

To learn about and check learning on the colour wheel, primary, secondary and tertiary colours. I have included the lesson powerpoint as it has the colour wheel I used to colour Justin Beiber's hair. Justin Beibhair is intended for a plenary task to assess learning; teacher presents the quiz and flicks through slides, stopping on one, pupils write down whether they think its primary, secondary or tertiary, either individually or in pairs/groups. I haven&'t had the chance to use this yet despite making it so let me know what you think.
