Hi there,
wow,u stay in Cheras?me too
I know about montessori,but this is the first time I hear about Nuh's Ark Islamic.by the way,my question is are you in malay race? If you would like to know where is the near monte in cheras,what can I suggest is Mayter;which is at Taman Connaught.Recently I got their brochure,it mention that they apply montessori method for their education program.You can try to contact them or straigt away go to their place for further information(you can see Mayter is on your right side,near shop lot-if you in the highway-Connaught to KL) or maybe you can contact the HQ of montessori world in Malaysia.You can find the related contact and info here
