My cousin teaches at a primary school in Warsaw. Visiting in April, I asked her what her new Ukrainian students were like. ‘They are all different,’ she said. Some Ukrainian refugees at Polish schools are taught in parallel programmes but others have joined regular classes. National limits on class sizes have been lifted. A Ukrainian school opened last month in central Warsaw. Some children have online lessons with their teachers from Ukraine. Some may not go to school at all. If I had saved my children from being shelled and living in basements, I might also prefer for them to play.
