SEQUENCES This presentation includes 3 activities based upon sequences of numbers and shapes. i) Activity 1 tests nth terms. ii) Activity two presents a number of sequences and asks for the next two terms. iii) Activity three presents a number of geometric patterns and asks for the next shape in each sequence. Similar to I.Q. test questions. Answers are given interactively. http://www.mathsguru.co.uk/
