These collections of problems introduce number sequences and representations, with problems for older secondary students focussing on summation of series. Each problem has detailed teachers' notes with suggestions for classroom use.
The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the
NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to
embed rich mathematical tasks into everyday classroom practice. More information on many of our other activities
can be found here.
