More than a million British children still lack access to a computer at home, research has revealed.
Nearly two million kids also cannot get online at home, said digital education charity the E-Learning Foundation, with children from the poorest families two-and-a-half times less likely to have the internet at home than those from more affluent backgrounds.
The charity, which aims to get every school-age child online, warned that children from low income families were being left behind as computer access continued to grow in better-off homes.
Valerie Thompson, the foundation's chief executive, said: "With so many children swamped with gifts from family and friends over the Christmas period it is important we reflect on the fact that millions of children live in poverty in this country.
"For those at school, this translates into very tangible disadvantages when it comes to completing homework, researching topics, independent learning, and communicating with teachers and classmates on the school learning platform.
"Without the use of a computer and the ability to go online at home the attainment gap that characterises children from low income families is simply going to get worse."
More than 50% of teachers who completed a November survey for the Times Educational Supplement said that children's education was hampered if they did not have access to a computer and the internet at home.
