**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.
