If you want kids to understand what the world looks like, put a physical globe in every elementary classroom. This will give them a starting point from which to understand how different flat projections work.

IIRC my daughter used to have an inflatable plastic ball with a Earth political map on it, it's cheap enough to give each kid their own globe.

I went to school in virginia and we had globes. Did you guys not have globes in other states?

This.

Bonus, it helps make clear what is wrong with many flat-earthers assertions.
