This student (who had special needs) normally struggled to engage with classwork but had a strong interest in superheroes, with Captain America being his favourite.
I then superimposed one of his normal regular worksheets onto a background image featuring one or more of his favourite characters using photo editing software I put together an A3 sheet template featuring Captain America.
When I presented the adjusted worksheet to the student, his face lit up immediately and he immediately became greatly engaged in the task and was very eager to work hard.
