Introduction to Directed Number with KS3 or lower ability GCSE. Introductory questions, together with Whiteboard questions. Review of adding/subtracting negative numbers before treasure hunt activity. Print out 18 Treasure hunt cards and distribute around the room. Students can start on any card by looking at the question at the bottom. They should make a note of the letter in the bottom Left hand corner and then try to solve the question. They will then need to look around the room to find a card which has their answer at the top. They should again note down the letter in the bottom left hadn corner; attempt the question; find the next card etc. If pupils complete all 18 questions, they should recognise there are two works ISOSCELES TRIANGLE- but some may spot the pattern and predict the words (which is fine too). Once they bring you a picture of this, provide them with the extension questions (last slide) which gets them to explore the rules with multiplying/ dividing by negatives. MWB questions to review that also integrate BIDMAS. Please review.
