The iSMART program combines learning with games, which my child really enjoys. I've noticed my child can speak more, and they're very enthusiastic about studying at home.
My child told me they learn Math, Science, and human body parts. Normally, if I asked, they wouldn't know, but after studying the iSMART program, I tried asking them what "head" and "hand" are in English, and they could answer. They can even count from 1 to 100 in English, even though the regular Vietnamese curriculum hasn't covered numbers up to 100 yet. This has also stimulated them to explore more and be less shy than before.
