After playing, it's study time!
I let them enjoy themselves both in playing and reading. Unlike many other parents who let their kids go to the tuition and/or enrichment classes, I let them study on their own pace. I let them think, understand what they are taught, not repeat and/or memorize every single words they are taught. I let them find out what the problems in their study and got the problems solved by themselves. This is how I brought up the sons.
For your reference, the sons got the EESIS scholarships, the younger was an IP (Integrated Programme) & gifted student with straight A's in his A level examination ( 4 H2 + H3 papers). Sorry, no means to show off or whatever. I'm just another bragging mom who always proud of her own kids. :)
