A daily dose of computer games can boost maths attainment, according to a study carried out in Scottish schools.
Learning and Teaching Scotland - the main organisation for the development of the curriculum - analysed the effect of a "brain training" game.
It also found improvements in pupils' concentration and behaviour.
The study involved more than 600 pupils in 32 schools across Scotland using the Brain Training from Dr Kawashima game on the Nintendo DS every day.
A group of pupils played the game, which included reading tests, problem-solving exercises and memory puzzles, for 20 minutes at the start of their class for nine weeks. A control group continued their lessons in a more traditional manner.
The pupils were tested at the beginning and then the end of the study.
Researchers found that while all groups had improved their scores, the group using the game had improved by a further 50%.
