Montessori in Singapore is SO different than a Montessori you may be familiar with from other places. They do not teach thinking or generalization skills here. I have seen kids who are able to add and subtract only using spindles or sticks, as well as recognize phonics only with wooden letters, but are not able to answer simple questions like "how many cards do you have in your hand?" (the particular child was counting -1,2,3,4... and there was no final answer, asked again - started from one). I will avoid local Montessori for my child as much as possible.
If you plan to send your child to a local primary school, then you do not have to worry about him being bored. The academic demands here are c-r-a-z-y, teachers are not able to go through the curriculum thoroughly, I've been told couple of times by parents that this is a tutor's role to help the kids understand the topic. Teacher's role is to mention it in the school.
