The children are Rohingya refugees and the house is a private school where they learn Malay, English, math and science.
This life is light years away from the one the children left behind in Myanmar.
"People were getting hit and killed and the police were arresting people. My whole village was burned down," 13-year-old Anwar Sadek Shah Ahmad says softly, cowering into his teacher's shoulder.
Anwar and his family fled their fishing village in Myanmar's Rakhine State in 2013 after violence broke out.
His grandmother, he said, only fled Myanmar last year and is now in a refugee camp in Bangladesh, where more than 680,000 Rohingya have fled to since August 2017.
There are thousands of children like Anwar in Malaysia —
he's among the Rohingya refugees who escaped from Rakhine State by boat largely before 2015, when Kuala Lumpur began turning back Rohingya arrivals.
Even though they consider themselves the lucky ones, those who made it to Malaysia still lead lives fraught with risk and hardship.
"They have no legal rights — no right to work, no opportunity for mainstream education, and are obliged to eke out a very difficult living in the grey market economy of the country," said Richard Towle, the United Nations High Commissioner for Refugees (UNHCR) Representative for Malaysia.
This is the case for all refugees in Malaysia. Most of the 150,000 refugees there are from Myanmar, but there are also Pakistanis, Syrians, Yemenis and Palestinians.
