Frequently asked questions
- What is number sense in Singapore Primary Math?
- Number sense is understanding how numbers work — place value, comparing quantities, number bonds to 10 and 20, and mental strategies for addition and subtraction. It is the foundation before bar models and fractions.
- What operations do P1–P3 students learn?
- Addition and subtraction within 1000, multiplication tables (2, 3, 4, 5, 10), simple division, and comparing/ordering numbers. Word problems use everyday Singapore contexts.
- What are common Primary number sense mistakes?
- Misreading place value (e.g. 305 vs 350), carrying/borrowing errors, and not checking answers with inverse operations. Encourage drawing or number bonds before jumping to column methods.
