Lunch breaks will be staggered and pupils will be restricted to mingling in the yard with only their own classmates under new rules set out in the Government's roadmap for reopening schools.
Primary school children will be sectioned off into pods of between four and six pupils in classes and separated by at least a metre from their classmates.
Meanwhile, secondary school students will be asked to wear masks on school buses, but wearing them in classes will be optional.
State funding will be provided for primary and secondary schools so yards can be divided up to allow for segregated outdoor areas for pupils during lunch breaks.
Education Minister Norma Foley's plan has also cleared the way for the return of interactive subjects such as PE, music, computer science and metalwork.
However, strict cleaning regimes will have to be implemented by schools if they intend to hold classes that involve pupils interacting with each other and using equipment.
Ms Foley's €300m plan will involve major investment in sanitation and personal protective equipment and fund significant changes to school buildings to make sure they are compliant with Covid-19 health and safety standards.
An additional €30m will be made available for supervision hours during break times when teachers will try to ensure pupils continue to follow social distancing rules outside their classrooms.
There are also plans to make more part-time teachers permanent.
There will be separate funding for special education schools, with €3.8m being set aside for extra special needs assistants (SNAs) and substitute teachers.
However, central to the plan will be new social-distancing rules for pupils when they are in class, on the way to school, and in the yard during their breaks.
The Government will provide funding to Bus Éireann and other school bus providers to allow them to make changes to their vehicles which will lessen the spread of the virus.
In line with public health advice, students aged over 13 will be asked to wear masks on buses.
However, students will be encouraged to cycle and walk to school where possible.
Schools will have discretion to stagger their hours to ensure pupils do not all arrive at the same time.
In primary schools, pupils in junior infants through to second class will be exempt from social-distancing rules as the Department of Education believes it is too difficult to make young children adhere to the restrictions.
However, classrooms will be reconfigured for pupils in third to sixth class to allow for individual pods of between four and six children and these pupils will be told not to share class equipment with classmates who are outside of their pod.
These pupils will be expected to remain together at their desks during lessons but will be able to mingle with the rest of their classmates during breaks.
In some cases, two year groups may be allowed to mix during breaks, but it is recommended that where possible they are kept separate.
The aim is to keep primary school pupils in what are being called their classroom "bubbles".
Extra funding for substitute teachers will be made available to ensure classrooms are not split if the regular teacher is sick or displaying coronavirus symptoms.
Secondary school students will be kept at least one metre apart from each other and teachers will move between classes for lessons to reduce the movement of pupils around school buildings.
In instances where students and staff are asked to move between classes they will all be asked to wash their hands.
Schools will also be asked to introduce staggered times for lunch breaks, especially if they have on-site cafeterias.
Yesterday, Tánaiste Leo Varadkar said the plan will involve significant changes to school buildings, hiring more teachers and strict cleaning regimes.
"A lot of work has gone into it, there has been a lot of consultation with the unions and I think it's a good plan," he said.
"I'm confident that it will go through Cabinet and will allow us to open schools for all one million students."
Labour Education spokesperson Aodhán Ó Ríordáin said more clarity was needed on how the Government intended on spending the €300m earmarked for reopening the country's schools.
"If the package is at least €300m it is essential that we get clarity on how many extra teachers and special needs assistants will be hired to help," he said.
"We have some of the highest class sizes in Europe and this is our chance to finally reduce them."
The intention to publish the plan tomorrow for how schools are to reopen fully and accommodate every child this September is most welcome. But that doesn't mean we shouldn't question that most laggardly of ministerial departments - the Department of Education and Skills (DES) - about why this plan is being put into the public domain less than a month away from the normal school reopening date.
