He retained his memory for maps and loved travel....and how he was taught was so simple....during the depression years..
The class made maps...topographically correct from a mixture of flour, water and maybe salt as a preservative.
I suppose the teacher had one of those really old pull down maps on the wall that the class tried to copy... ( obviously many years ago)
Anyway, they got a thick glop of the flour/water/salt (I think it was salt) mixture on a board, maybe on cardboard....and they sculpted the mountains, rivers and plains. Probably the class recreated the St Lawrence River ...
The mix hardened in a day or so into a solid map..maybe they colored rivers, forests etc with food coloring.
When he was older, his Mother had a map of the world taped to the kitchen wall above a table....and when he and his friend were there..she arranged a game of who could find the capital of XXX. Fastest... But that was before TV!
But a little person might get great pleasure from sculpting mountains, rivers and plains...... as long as they did not ingest the mixture.
