NRICH Projects: Number Rules, Functions and Graphs - March 2010, Stage 2&3

This month's NRICH site looks a little different - instead of starting the month with problems, we are offering starting points for projects.

Working on these projects gives learners opportunities to work together, discuss ideas, develop conjectures of their own, and suggest new lines of enquiry.

During the month we will add problems based on the questions and conjectures posted by learners.
