Ask HN: What gift could one buy a semiliterate 14 y/o boy returning to school?

I’m staying in Lahore, Pakistan. I met the 14 y/o son of friend’s servant. The story is that he dropped out of school about 6 years ago, and wants to go back. He’ll be starting off with basic reading, writing, and arithmetic. I was thinking I might buy him a small gift to encourage his learning. Any ideas on what could make a meaningful, appropriate gesture to a kid in this situation? I’ve never met a 14 y/o who couldn’t read well, and I have not idea what to offer.
