Turkey has been imposing blanket curfews over the last few weekends in 31 cities.
Over-65s will be allowed to go out "only within walking distance" for a few hours a day from 10 May. Similar rules will apply to children.
Erdogan said shopping malls, barber shops and some stores will be allowed to reopen on 11 May. Universities will return on 15 June.
But Erdogan warned that much stricter measures would be put in place if the public does not abide by the rules.
“This normalisation plan does not mean we’ll be back to our days as of the first days of March,” he said.
According to Turkey’s Ministry of Health, the death toll in the country has risen to 3,461.
The National Rifle Association (NRA) - the largest pro-gun lobbying group in the US - has furloughed workers (given them temporary leave) and cut salaries due to the coronavirus pandemic.
The group's annual convention - which probably would have drawn a visit from President Trump - has also been cancelled.
"The cancellation of the annual meeting had a significant financial impact but, beyond that, the health crisis has caused us to postpone countless fundraising and membership events," said NRA spokesman Andrew Arulanandam.
The virus has caused a record spike in US gun sales, according to the FBI.

The number of people who have died with coronavirus around the world has passed a quarter of a million - rising to 250,134, according to figures published by Johns Hopkins University.

At least six more US states are loosening social distancing measures starting on Monday.
Gyms in Arkansas can resume operation, as long as clients have their temperatures screened before entering. Florida beaches and parks can reopen, but not in the Miami area.
Missouri businesses can open, but customers must keep six feet (two metres) apart. Nonessential businesses in Colorado are also permitted to reopen, but with limited capacity.
Ohio’s governor is allowing manufacturing, construction and office work to resume starting on Monday. Retail shops are expected to reopen on 12 May.
Indiana is moving towards its second stage of reopening and is allowing social gatherings of up to 25 people. But residents over 65 are encouraged to remain at home.
Around half of US states have begun taking steps to reopen, even as health officials warn that the pandemic is not yet under control.
Image source, Getty ImagesThe number of unemployed Austrians reached a record high in April, the country's news agency ANA reports. Figures showed 571,477 people, or 12.8% of the population, were unemployed - up more than 210,000 from the same time last year.
Austria, which has 15,621 coronavirus cases and 600 deaths according to Johns Hopkins University, began relaxing its restrictions and allowing some shops to reopen in mid-April.
Football matches in the UK are likely to be played behind closed doors for an extended period because of bans on mass gatherings amid the coronavirus pandemic.
FA chairman Greg Clarke has said it is hard to see fans returning "any time soon" and the Premier League is preparing for the possibility of playing next season without fans.
So what would be the impact of a season without fans on the Premier League clubs? BBC Sport and football finance lecturer Kieran Maguire has taken a look.
Research suggests Arsenal generated nearly a quarter of their total income from matchday last season, making them vulnerable financially.
Image source, Getty ImagesPlayers in the top two flights of football in Spain will return to training this week with the hope of the leagues restarting in June.
They will initially train alone but a "staggered return to training" will be implemented with players training together at a later date.
Football in Spain was suspended indefinitely in March because of the coronavirus pandemic.
In the UK, the Premier League hopes to resume on 8 June but there is disagreement between the clubs on how to move forward.
In Germany, clubs have been training in groups before a planned return to training as teams. The German league could restart on 16 or 23 May.
It has already been announced that the top leagues in France and the Netherlands will not resume.
UK officials said on Monday it was "perfectly reasonable" to look at how guidance about the next stage of coronavirus restrictions could apply to different age groups.
The prime minister’s spokesman pointed to the fact that over-70s had already been advised to take particular care and minimise contact with others outside their households, due to the fact they were classed as a clinically vulnerable group.
He said: “As we go forward it’s perfectly reasonable we look at how the guidance will apply for different age bands and we will continue to be guided by the science.”
People over 70 are more likely to have serious symptoms of the virus, but they are not automatically in the "extremely vulnerable" group of people who have been asked to "shield".
Over the weekend, several public figures, including actor Michael Palin, called on the government to ensure older people were not unfairly separated from society as lockdown was lifted.

France could allow religious services to resume earlier than planned if the easing of the lockdown this month does not result in an increase in the infection rate of coronavirus.
France is set to ease its lockdown on 11 May but it had been indicated that religious ceremonies would still be banned until at least 2 June.
The Christian holy day of Pentecost, celebrated 50 days after Easter Sunday, falls on 1 June.

In Hungary 84,000 pupils were back in classrooms on Monday to sit their high school exams, despite the country's lockdown.
Most appeared relieved that the exams were not postponed, but teachers’ unions and parents voiced concerns that pupils and staff might spread coronavirus.
Written exams have been condensed into two weeks, and no oral exams will be held.
The mood was festive outside the Bela Bartok music gymnasium in central Budapest. Pupils who hadn’t seen each other for six weeks gathered in their best clothes, bumping elbows or knuckles in greeting, but there was no hugging or kissing.
They filed into classrooms one by one, and about half wore face masks. At some schools police patrolled to enforce social distancing, but not here.
Inside, seven students sat in each classroom. Masks were not compulsory during the exam, although supervisors kept theirs on.
The main teachers’ union was not consulted by the government, and opposed the decision to go ahead with the exams.
With 3,000 known coronavirus infections and 350 deaths, the peak has still not been reached in Hungary.
New York Governor Andrew Cuomo said in his Monday briefing that current data showed that no region of the state - which remains the epicentre of the pandemic in the US - is yet ready to reopen.
There were 226 deaths in New York state on Sunday, down from 280 in the previous 24-hour period.
But Cuomo said that new cases and deaths were not dropping as quickly as they first rose in the earliest days of the outbreak.
"Unfortunately we were hoping a quick up, plateau and a fast decline," Cuomo said. "The decline is not as steep as the incline."
A British headteacher says he has spent £2,000 of his own money buying food for vulnerable families who are waiting to receive an alternative to free school meal vouchers.
Lloyd Mason-Edwards, from Bradford in Yorkshire, said only about half the families eligible at his school had received them.
The UK government has in England been converting free school meals for poorer children into supermarket vouchers since closing schools in March.
He said the system was a "shambles" and was failing those in need.

Image source, ReutersEvery time people cough, sneeze, talk or even breathe they can spread droplets containing the virus.
That’s the rather graphic conclusion of the Royal Society, Britain’s oldest and most prestigious scientific academy.
It highlights the risk of the virus being spread by people who don’t realise they have it - either because they’ve yet to develop symptoms or because they never show symptoms at all.
This is how an estimated 40-80% of coronavirus infections happen and that’s why the panel recommends face masks.
The report stresses that high-quality masks should be reserved for medical and care workers.
But it says homemade face coverings can be effective, not at protecting the wearer but at preventing the wearer from infecting others where social distancing isn’t possible, on public transport and in shops and workplaces.
The issue has become highly divisive. Some researchers say the Royal Society’s report has ignored the risk to the public, for example, of contaminating themselves when handling masks.
The UK government is still considering the evidence.
It's hay fever season in some parts of the world, and the symptoms can be similar to those of coronavirus - so the UK's Royal College of General Practitioners is warning people not to mix them up.
It says it's concerned people may go outside thinking they've just got the seasonal illness, when actually they have contracted the virus and should stay at home.
Our health correspondent Laura Foster explains how to tell the difference.
Hay fever or coronavirus: The symptoms compared
Philippa Roxby
Health reporter, BBC News
Whether people who are infected by the virus could catch it for a second time is a question no-one yet knows the answer to.
The key is whether antibodies build up in the bloodstream when the body fights off this coronavirus, and how long they last afterwards to protect people from further infections.
Early research suggests good news. Most people do appear to develop antibodies but how long they stick around for is still a mystery.
Regularly following up people who’ve tested positive for a number of years is the only way to find out how long immunity might last.
The UK's health secretary himself is participating in a study after contracting the virus several weeks ago.
Are the antibodies still present? Are they at the same level? Only time will tell…

Image source, PA MediaWe are, declared the prime minister at the end of last week, past the peak of the coronavirus pandemic in the UK.
But he said we'd have to wait until this week to learn more about how we'll start to move out of the lockdown that has changed the country so dramatically in the past six weeks.
Given that the crisis has affected pretty much everyone in one way or another, there is a fevered guessing game well under way about what moving out of the lockdown might look like - and it involves huge dilemmas for the government.
With another six days to go before the prime minister is expected to spell out those choices, some things are clear. First and foremost, the government is not about to throw the country's doors open.
Read more here on what easing lockdown could look like from our political editor Laura Kuenssberg.

Finland is going to allow restaurants, public services including libraries and sports facilities to reopen on 1 June.
A ban on public meetings will also be eased from a maximum of 10 people to 50 people on the same day, the government said on Monday.
Image source, Getty ImagesFewer Americans are remaining at home each day, according to a new study of mobile phone tracking data, external from the University of Maryland.
The anonymous location tracking data indicate a growing level of "social distancing fatigue", say the researchers at the Maryland Institute of Transportation.
The researchers created a software code that creates a score for each state, called the Social Distancing Index, to determine how many residents are travelling away from their homes.
Across the nation scores are dropping, indicating that gradually more and more Americans are venturing into public.
Washington DC, where the rate of new cases is still growing, has the best social distancing score. Wyoming has the worst.
