How much time is spent on maths and science in primary education?
In 2015 on average across OECD countries, maths counted for 45 minutes of instruction time per day in primary education, and natural science for another 20 minutes. In relative terms, this translates to 17% of time devoted to maths and 8% devoted to science. So, on average primary schools across OECD countries spent approximately the same amount of instruction time on maths and science combined as on language. Thus, the core subjects of language, maths and science account for half of the total instruction time in primary education. - See more at: http://oecdeducationtoday.blogspot.com.es/2016/02/how-much-time-is-spent-on-maths-and.html#sthash.E1JktCYY.dpuf
