I created this project for my Year 3 class, but it could be easily adapted used in Y4 or higher. I based a whole week around it, including thinking skills, applying maths skills, designing products and advertising. I split my class into mixed ability teams for the week. The powerpoint file introduces the task, and contains instructions for every part of the task as you go through the week, including examples to demonstrate each maths activity. The maths activities are all differentiated for higher, middle and lower ability groups, and include calculating factory opening times, converting distances between metres and kilometres for 'distribution' and calculating production costs (multiplying by 2, 4 or 40). There are group thinking skills templates, which I enlarged to A3 for groups to brainstorm ideas for cereal types, flavours and brand names. There are also templates for designing a cereal box, an advertising poster, and a cartoon strip-style planning sheet to storyboard ideas for a TV advert. Afterwards, we filmed an advert for each group using an iPad and green screen.
