Scratch works pretty well on the iPad for programming, and there's Scratch Jnr for younger learners. Repl.it also works well on the iPad, as long as you sign in for them, so they can play with any language they like. If you want an actual computer that they can play around with that's cheap then a Raspberry Pi is a good choice. The Pi 400 with it's integrated keyboard is excellent. If you want some programming projects then have a look at https://projects.raspberrypi.org/en https://projects.raspberrypi.org/en They're not just projects for using the Raspberry Pi. There's a tonne of Scratch, Python and HTML stuff for them to work through as well. I'd suggest https://projects.raspberrypi.org/en/pathways/scratch-intro https://projects.raspberrypi.org/en/pathways/scratch-intro if they've never used Scratch before. All the projects are tablet friendly as well.
