In Primary 6, your child was taught how to solve math problem sums (word problems) by identifying CONCEPTS, such as “guess and check” (there are 12 concepts in total).
If they mastered CONCEPTS, they’ll probably score well in math. However, in secondary 1 concepts are no longer required.
The Secondary 1 syllabus is focused on TOPICS, such as Whole Numbers, Fractions, Angles, Geometry, Speed, Volume etc.
So what’s the problem?
Your child will not be able to easily apply what they learned in P6, to the Secondary 1 syllabus.
It IS possible to bridge the P6-Sec1 gap, but schools don’t teach this (more on this below).
