Primary 2 Mathematics

Students count, read, and write numbers up to 1000, using concrete materials and place value charts to represent hundreds, tens, and ones.

Students decompose 3-digit numbers into their hundreds, tens, and ones components and understand the value of each digit in its position.

Students compare and order numbers up to 1000 using place value understanding and symbols for greater than, less than, and equal to.

Students identify, continue, and create number patterns by skip counting in twos, threes, fours, fives, and tens up to 1000.

Students add two 2-digit numbers that require renaming (regrouping) ones into tens, using concrete materials, pictorial representations, and the column algorithm.

Students subtract two 2-digit numbers that require renaming (regrouping) a ten into ones, using concrete materials, pictorial representations, and the column algorithm.

Students add and subtract 3-digit numbers with and without regrouping, applying the column algorithm and mental strategies for numbers within 1000.

Students solve 1- and 2-step word problems involving addition and subtraction of numbers within 1000, using bar models to represent the problem structure.

Students understand multiplication as combining equal groups and recognise arrays as a visual model for multiplication, connecting repeated addition to the multiplication symbol.

Students build fluency with the 2, 5, and 10 multiplication tables by identifying patterns, skip counting, and practising recall.

Students build fluency with the 3 and 4 multiplication tables, using arrays, number lines, and pattern recognition.

Students understand division as equal sharing (partitive division) and equal grouping (quotitive division), connecting division to multiplication fact families.

Students solve 1-step word problems involving multiplication and division within the 2, 3, 4, 5, and 10 times tables, using bar models to represent the problem structure.

Students measure length using metres and centimetres, read rulers correctly, and understand the relationship between the two units.

Students measure and compare mass using kilograms and grams, read weighing scales, and understand the relationship between the two units.

Students measure the volume of liquids using litres, read measuring containers correctly, and compare the volumes of different containers.

Students solve 1- and 2-step word problems involving length, mass, and volume, including adding, subtracting, and comparing measurements.

Students identify and describe Singapore coins (1¢, 5¢, 10¢, 20¢, 50¢, $1) and notes ($2, $5, $10), and represent amounts of money in different ways.

Students add and subtract amounts of money in dollars and cents, including making change when paying for items.

Students solve 1- and 2-step word problems involving buying, selling, and making change using Singapore currency.

Students identify, classify, and describe common 2D shapes (squares, rectangles, triangles, circles, semi-circles, quarter circles) by their sides and corners.

Students identify, name, and describe common 3D shapes (cubes, cuboids, cylinders, cones, spheres, pyramids) by their flat and curved faces, edges, and vertices.

Students identify lines of symmetry in 2D shapes and pictures, complete symmetrical figures, and recognise shapes with no lines of symmetry.

Students identify, continue, and create repeating and growing patterns using 2D shapes, describing the pattern rule.

Students read and interpret picture graphs where each symbol represents more than one item, using the scale to determine totals and make comparisons.

Students collect data, choose a suitable scale, construct picture graphs, and answer questions that require reading totals, differences, and comparisons from their graphs.

Students divide shapes and sets into two and four equal parts, name the parts as halves and quarters, and use fraction notation (½, ¼).

Students divide shapes and sets into three equal parts, name the parts as thirds, and extend understanding to other unit fractions using fraction notation.

Students compare and order unit fractions (½, ⅓, ¼) by reasoning about the size of equal parts and using fraction strips.

Students read and write time to the nearest 5 minutes on analogue and digital clocks, using "past" and "to" language for times around the hour.

Students calculate the duration of events in hours and minutes by finding the difference between start and end times.

Students read and interpret calendars, identifying days of the week, months of the year, and solving simple problems involving dates and durations in days.

Students develop and apply mental strategies for adding and subtracting 2- and 3-digit numbers, including making tens, compensating, and using known facts.

Students identify odd and even numbers up to 1000, explain the pattern in the ones digit, and explore what happens when odd and even numbers are added together.

Students solve 2-step word problems that combine any two of the four operations, choosing the correct operations and using bar models to plan solutions.

Students estimate the results of addition, subtraction, multiplication, and division calculations and use estimation to judge the reasonableness of answers.

Students apply bar models systematically to plan and solve a variety of word problems involving whole numbers, money, and measurement.

Students explore number patterns and relationships across the four operations, making conjectures and testing them with examples.

Students apply knowledge from across the year to investigate open-ended real-world scenarios, communicating reasoning and presenting solutions.

Students engage with non-routine problems that require logical deduction, systematic thinking, and creative problem-solving strategies.

Students apply a range of mathematical concepts from across the year to solve complex, multi-step problems and reflect on their mathematical growth.
