HP48 - Children 'Games' Educational Code recommendations

[TomC]

Please share any successful experiences with available (on the Calc/Museum sites) programs for a child 3 to 6 years old - to run on an HP48G.

It's most interesting to see how a child can be entertained by just watching numbers count and/or scroll by - Games/educational stuff like flash cards (large numbers), 'Worms' would be entertaining.

I know there's a lot of code out there - just hoping to get opinions on positive experiences.
(preferably user code so I could easily mod if necessary).

Thanks,
TomC
