I started my oldest with doing puzzles (jigsaw) and logic-based games. He's now 8 and is very good in the math subjects. Language is less good.

For language I have him reading English-language books, that might have been a bad idea because it's his second language. He is "okay" at his native language.

His sister we did nothing with; her language skills are excellent in her native language, but she's not as good at Math as the oldest. We're not starting her reading English for at least another year.

The youngest, well, he is only starting to talk now. They take a little longer to start because they're dual language (Dutch/English).
