Patterns in Number Sequences

Summing Consecutive Numbers

Age 11 to 14
Challenge Level Yellow star

This problem offers a simple context for students to explore, make generalisations and prove conjectures, working numerically and algebraically.

Shifting Times Tables

Age 11 to 14
Challenge Level Yellow star

This problem encourages students to think about the properties of numbers. It could be used as an introduction to work on linear sequences and straight line graphs.

Charlie's Delightful Machine

Age 11 to 16
Challenge Level Yellow star

This problem could be used to reinforce work on recording and describing linear sequences.

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.

NRICH is part of the family of activities in the Millennium Mathematics Project.
