Major Programmes/Activties/Achievements/Highlights


To nurture Logical Thinkers, Analytical Problem Solvers and Creative Minds

Aligned to the school learning direction, the Mathematics department has infused Assessment for Learning (AfL) and Differentiated Instruction (DI) in our Mathematics lessons to meet the different learning needs of our pupils. The department has adopted the Flip classroom approach to further engage our students in the learning of Mathematics.   

The effective use of technology is also an integral part of the teaching and learning of Mathematics for our students at Hai Sing Catholic School. Our students are engaged in interactive ICT lessons through tools such as customized Excel spreadsheets, Graphmatica, GeoGebra and a Math e-learning portal.

Apart from the conventional classroom lessons, our team of teachers believes in always seeking innovative pedagogical approaches to make the learning of Math fun and dynamic. An annual tradition, the Math department organizes a Math Trail at the Changi Airport for the lower secondary pupils to enhance and enrich their learning experiences outside the classroom. Through these activities, pupils were given the opportunity to apply their mathematical knowledge to investigate situations, model real-life phenomena and solve problems. 

The following are the achievements of our pupils for the competitions participated this year.
