Primary Math with Mr Ong

PSLE Math Heuristics, Primary Math concepts and problem-solving strategies for P3–P6 students in Singapore.

I'm Lawrence Ong (Mr Ong), a Primary Math Heuristics Specialist and NIE-trained former MOE teacher with over 25 years of teaching experience.

On this channel, I teach PSLE Math and Primary Math step by step, including Model Drawing, Assumption Method, Working Backwards, Finding a Pattern, Grouping, Ratio, Fractions, Decimals, Spatial Visualisation, PSLE Math Paper 1 and more.

I am also the founder of Math Learning Groups (MLGs) and Heuristics Mind, where I provide Primary Math tuition, online lessons, PSLE Math Heuristics Masterclasses and learning resources for P3–P6 students.

My goal is simple: help students understand Math, solve problems systematically and become more confident independent problem solvers.
