Coding: Ten-year-old computer programmer backs school change
From Monday, children as young as five will be taught how to write computer code as part of far reaching changes to the curriculum in English schools.
It means that more than 160,000 primary school teachers have had to learn a whole new subject in time for today's deadline.
Teaching unions have welcomed the changes but say it should have been phased in more slowly.
Ten-year-old Max started writing code after his mother gave him a laptop when he was six.
He told BBC News why he thought more children being taught how to program was a good idea.
