Primary maths

Tuhattaituri – One of the reasons behind the Finnish PISA success.

The Tuhattaituri series follows the new Finnish curriculum. The content helps pupils make progress in their numeracy skills. Pupils learn fundamental mathematical concepts and skills at a manageable pace. There are also maths problems to solve as well as tasks to investigate, coding activities and other ways to reinforce pupils’ skills. Learning is facilitated through a variety of task types and tools for individual and group work. The accompanying digital resources help pupils consolidate and extend their knowledge.

Tuhattaituri and the new Finnish curriculum

  • Fun and cooperative learning are central to the entire series.
  • Materials make it easy to bring variety to your teaching.
  • Tuhattaituri provides tips for multi-sensory maths teaching.
  • Materials include tasks to promote pupils’ coding skills. The Teacher’s Guide contains more tips on working with code.
  • Pupil coursebooks include investigative tasks and experiments to promote pupils’ ICT skills.
