That's great to hear! The more well-guided children we have today the better world we would live in tomorrow.
The only thing maybe, we shouldn't forget or allow to slip from our intention is that children approach and understand things (especially some serious ones) differently than we do. As well they need time to play. Therefore, I believe more we manage to incorporate learning into a playful game in which they would enjoy and have some fun too, the more they would be eager to learn and greater successes they would achieve.
