Developing Problem-solving Skills

Age 5 to 7

Trial and Improvement at KS1

These lower primary tasks could all be tackled using a trial and improvement approach.

Age 7 to 11

Trial and Improvement at KS2

These upper primary tasks could all be tackled using a trial and improvement approach.

Age 5 to 7

Working Systematically at KS1

Tasks for KS1 children which focus on working systematically.

Age 7 to 11

Working Systematically at KS2

Tasks for KS2 children which focus on working systematically.

Age 5 to 7

Working Backwards at KS1

The lower primary tasks in this collection could each be solved by working backwards.

Age 7 to 11

Working Backwards at KS2

The upper primary tasks in this collection could each be solved by working backwards.

Age 5 to 7

Visualising at KS1

These lower primary tasks all specifically draw on the use of visualising.

Age 7 to 11

Visualising at KS2

These upper primary tasks all specifically draw on the use of visualising.

Age 5 to 7

Reasoning and Convincing at KS1

The tasks in this collection can be used to encourage children to convince others of their reasoning, using 'because' statements.

Age 7 to 11

Reasoning and Convincing at KS2

The tasks in this collection can be used to encourage children to convince others of their reasoning, by first convincing themselves, then a friend, then a 'sceptic'.

Age 5 to 7

Conjecturing and Generalising at KS1

The tasks in this collection encourage lower primary children to conjecture and generalise.

Age 7 to 11

Conjecturing and Generalising at KS2

The tasks in this collection encourage upper primary children to conjecture and generalise.

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.
