All children in England will go back to school full-time in September, under current plans.
The announcement was made by Education Secretary Gavin Williamson, who said: "School is vital to every one of our children".
In June, Year 1 and Year 6 students were allowed to return, but with no more than 15 pupils in each classroom.
Now plans are being made to make it safe for everyone to go back in time for the new school year, with class sizes expected to be larger again.
The news comes after the Prime Minister, Boris Johnson, announced a £1 billion fund to help England's children catch up with learning.
Schools are going to be told how the plans will work in the next two weeks.
But, some people don't think that this is a good idea and are worried about children's safety and class sizes getting bigger.
At the moment the government has told schools that desks should be spaced as far apart as possible and lunch, break, drop-off and pick-up times need to be spaced at different times of the day.
"There is no social distancing if you've got 30 children in one classroom," said Kevin Courtney, joint general secretary of the National Education Union.
Mr Williamson has stressed though to parents that "the well-being of your children is the absolute top priority for every single one of us".
The current school opening plans aren't the same in England, Wales, Scotland and Northern Ireland.
Social distancing in schools has been reduced to one-metre in Northern Ireland, where plans are in place for a full reopening of schools in September.
