Explore mathematics topics for Primary 4, mapped to the Singapore MOE syllabus.
Primary 4 asks learners to work confidently with larger numbers and to coordinate several forms of arithmetic. The Singapore MOE syllabus extends whole numbers to 100,000 and introduces factors and multiples. Fractions now include mixed numbers, improper fractions and fractions of a set; decimals develop to thousandths, with rounding and operations. Learners also measure angles in degrees and use properties of rectangles and squares.
Geometry and data add new ways to reason. Children find missing dimensions of rectangles from area or perimeter and work with composite figures made from rectangles and squares. The revised curriculum places nets of three-dimensional solids in Primary 4, alongside line symmetry and shape properties. Learners read tables and line graphs, and encounter pie charts as a way to represent data. Being able to interpret a diagram is as important as carrying out a calculation from it.
As procedures become longer, place value and estimation remain valuable checks. A learner can ask whether a rounded result is sensible, label units and look for a relationship between quantities before choosing an operation. In geometry, describing a shape's properties and keeping track of angle measures can make a multi-step problem clearer. The aim is to connect a method to the structure of the question.
Singapore Math Drills provides MOE-aligned Primary questions with progressive hints and worked solutions. Parents can use the interactive skill map to review practice progress and launch a targeted drill on a subtopic. If an explanation is needed, a learner can return to the worked steps and compare them with their own approach. Focused practice can help make a specific idea steadier without treating every session as a full unit review.
Primary 4 is a bridge between the early arithmetic foundations and the broader range of fraction and decimal work ahead. It is useful to notice whether your learner can move between a diagram, words and a number sentence, and whether they can explain why a strategy fits. These habits will support the more connected applications of fractions, percentages, ratio and measurement in Primary 5.
P4 extends whole numbers to 100,000 and adds factors, multiples, mixed and improper fractions, decimals to three places and degree measurement. Geometry includes composite area and perimeter, nets and symmetry, while data work includes tables, line graphs and reading pie charts.
