Singapore Primary 3 Mathematics Syllabus

This syllabus outlines the learning objectives for Primary 3 Mathematics, categorized into three main strands: Number and Algebra, Measurement and Geometry, and Statistics.

Number and Algebra

• Whole Numbers:
• Numbers up to 10,000 (counting, notation, place value, comparing, ordering, patterns).
• Addition and subtraction algorithms (up to 4 digits).
• Mental calculation (addition and subtraction of two 2-digit numbers).
• Multiplication and Division:
• Multiplication tables of 6, 7, 8, and 9.
• Multiplying and dividing within the multiplication tables.
• Division with remainder.
• Multiplication and division algorithms (up to 3 digits by 1 digit).
• Mental calculation (multiplication and division within multiplication tables).
• Fractions:
• Equivalent fractions (concept, simplest form).
• Comparing and ordering unlike fractions (denominators up to 12).
• Writing equivalent fractions (given numerator or denominator).
• Adding and subtracting related fractions within one whole (denominators up to 12).
• Money:
• Adding and subtracting money in decimal notation.

Measurement and Geometry

• Measurement:
• Length (kilometers, compound units, converting between km and m, m and cm).
• Mass (compound units, converting between kg and g).
• Volume (milliliters, compound units, converting between liters and ml).
• Time (seconds, finding start/end times and duration, 24-hour clock).
• Area and Volume:
• Area and perimeter concepts.
• Measuring area (cm² and m²).
• Perimeter of rectilinear figures, rectangles, and squares.
• Area of rectangles and squares.
• Geometry:
• Angles (concept, right angles, comparing angles).
• Perpendicular and parallel lines (concept, drawing).

Statistics

• Data Representation and Interpretation:
• Bar graphs (reading, interpreting, different scales).
