The investigation in NMCC is a mathematical task that the class should investigate carefully.

It is possible to solve the problem using various methods and strategies.

The challenge for the class will be to consider the different methods and strategies, compare and contrast them and to make a progress log that documents how they worked with the task as well as a subject report that shows their mathematical findings.

Advice will also be given to the teacher about how the work might be organised so that all of the pupils can make a contribution to the work that is undertaken in the class.

The adcice will be handed out by the national organizers.

Mathematical ideas and procedures can be expressed in many ways. We can use casual everyday language and the formal language of mathematics – both in spoken and written forms. We can use concrete materials, models and drawings to highlight a mathematical idea.

The work done by the class will be assessed by a jury consisting of teachers and mathematicians. For each task there will be criteria that fit the task.

The grounds for the assessment will be:

- An academic report that describes part A of the task
- An exhibition of part B of the task, presentable to an ”external audience”
- An oral presentation of part B of the task, presentable to an ”external audience”
