So, my mom is a teacher in a 3rd grade class (7-8 y/o kids). Apparently all the boys in her class are into Pokémon, and when my mom told them that I'm a Pokéfan since the very beginning they went absolutely bananas, and asked her if she could bring them something from me. I happily gave her my huge Pokémon card collection: all cards are very old (they barely reach the Johto sets), but it's not a part of the franchise I'm interested in, so I'm happy to give them to someone who's gonna play and collect them.
This morning they were absolutely astonished by the quantity of stuff I sent them, and apparently now I'm a PokéGod to them. They even asked my mom if i could come over to their class and teach them about Pokémon.
What should I teach them?
