English: Your shop is going to have a sale! Create a poster/ advert to promote your sale. How much off everything are you going to have? When is the sale? How long will the sale last for? You could even make a video/ TV advert.
Maths: Can you make a list of deals for your shop items? E.g. 1 necklace is £5:50, in the sale you get two necklaces for £10!
