Singapore is well known for its Mathematics performance around the world.
The curriculum does have key principles that it follows even after reviews and changes every few years.
Ministry Of Education has a syllabus guide that provides reference for all teachers as well as assessment.
The Singapore style of Mathematics uses manipulatives like most parts of the world but it has problem-solving component that may require model drawing to solve it.
Models are simply pictorial representation of the questions in rectangular boxes labelled with numbers and names. It helps to simplify questions for better understanding.
CPA approach is also a popular way to teach. A teacher would provide Concrete experience before Pictorial and Abstract concepts come in.
I hope the above short videoclip provides some information about the Singapore Math style for your educational reference.
