Member Rights: Individuals

Maths300 is designed to support professional development in schools. It is built on the assumption that all staff have access to the lessons as fuel for on-going conversation about learning mathematics. That is why 'Individual' is not listed as a category on our application form.

However, there are circumstances in which a teacher needs an individual membership. In these circumstances they join as a 'school' of 0 - 50. The following rights and responsibilities attach to this membership variation. Our preference is that you contact us before applying for membership in this form.

For as long as an individual remains a registered member of Maths300:
  • That individual may use, copy or reproduce any material from Maths300 to serve the educational needs of students under the member's instruction. Copies of material from Maths300 are subject to this licence.
  • All software may be used on a member's personal computer and may be used on other computers by students under the member's supervision. Software may not be used by teachers other than the member or by students not normally under the instruction of the member.
This is a generous licence and we ask that you respect it.
  • Distribution of Maths300 material beyond the uses specified in this licence is a breach of this licence.
  • Continuing to use Maths300 material if an individual membership has lapsed is a breach of this licence.
