Which educational curriculum is best to discover and analyse my toddlers intelligence; the a montessori or play based approach? Or any other?

Play is always the best way to arouse the child's brain. Through play, they learn more on development and trigger both sides of the brains. My toddler learnt through play and subconsciously develop the necessary skills. I tried to incorporate their learning through games and I am surprised that they learn faster than teach the conventional way.
