Now, after heavy monsoon rains submerged large parts of the country, her classrooms are flooded and many of the 200 students homeless, struggling to get enough food and caring for injured relatives.
Such extreme weather events in a short space of time have caused havoc across the country, killing hundreds of people, cutting off communities, wrecking homes and infrastructure and raising concerns over health and food security.
Jacobabad has not been spared. In May, temperatures topped 50 degrees Celsius, drying up canal beds and causing some residents to collapse from heatstroke. Today, parts of the city are under water, though flooding has receded from its peak.
In Khan's neighbourhood in the east of the city, houses have been badly damaged. On Thursday, she said she heard cries from a neighbour's house when the roof collapsed from water damage, killing their nine-year-old son.
Many of her students are unlikely to return to school for months, having already lost class time during the brutal summer heatwave.
"Jacobabad is the hottest city in the world, there are so many challenges ... before people had heatstroke, now people have lost their homes, almost everything (in the flood), they have become homeless," she told Reuters.
