Most pupils should prepare to learn at home until the start of the autumn term, the schools minster has confirmed.
The government has announced that three primary school years – reception, year one and year six – will return from Monday, 1 June, prompting a battle with teaching unions.
The prime minister and the education secretary have made clear their ambition that all primary school pupils should return for a month of lessons before the summer.
But Nick Gibb shed a more doubtful note on the timetable, telling MPs on the Commons Education Committee it is "difficult to say" whether more children will return to school this term.
"Remote education, home education, will continue for the majority of pupils and young people – probably until the end of the summer term", the schools minister said.
"We do want young children to come back into school if the science indicates that it's safe to do so. It's a balance.
"We're balancing the objective to return to school with the overwhelming objective of ensuring they are as safe as possible and that returning children to school does not result in an increase in the R factor (the reproduction number of the virus).

"That's why we are taking such a very cautious approach."
Asked by chair Robert Halfon, Tory MP for Harlow, why the government had presented it as a "fait accompli", he said it would be confirmed tomorrow when the Scientific Advisory Group (SAGE) releases its latest estimate of the R rate of COVID-19 in the UK.
The latest SAGE estimate last week kept the UK's rate between 0.7 and 1, the same as the previous week.
As to the return of more primary school pupils this term, Mr Gibb said: "We don't know until we see more evidence of the R factor continuing to reduce over the next few weeks."
He suggested that while the first primary school children will return full-time from next week, there may be a rota system for other young children due to lack of space in schools to implement social distancing.
Schools have received guidance from the Department for Education requiring them to reorganise their buildings to allow a maximum of 15 children per class.
