Primary 1 Mathematics
A comprehensive introduction to mathematical thinking through concrete exploration and pictorial representation. Students develop a deep sense of number, spatial awareness, and logical reasoning to solve real world problems.

01Numbers and Operations
Building a strong foundation in counting, number sense, and the four operations through concrete materials and pictorial representations.
Students will count objects up to 10 using one-to-one correspondence, recognise numerals 0–10, and match quantities to numerals.
Students will read and write numerals and number words for 0 to 10 and understand the meaning of zero.
Students will compare two numbers using the language "greater than", "less than", and "equal to", and arrange numbers in order.
Students will explore number bonds, understanding how two parts combine to make a whole within 10.
Students will add two single-digit numbers with a sum up to 10, using concrete objects, pictures, and number sentences.
Students will subtract within 10, understanding subtraction as taking away and as finding the difference.
Students will count, read, write, and compare numbers from 11 to 20, recognising ten as a unit.
Students will add numbers with sums up to 20, building on number bonds and using the make-ten strategy.
Students will subtract within 20, using number bonds and the make-ten strategy to solve problems.
Students will understand tens and ones as place value units, count in tens to 100, and represent numbers using base-ten blocks.
Students will count forward and backward in tens from any multiple of ten up to 100.
Students will read and write numerals and number words for numbers up to 100.
Students will compare and order two-digit numbers using place value understanding and the symbols <, >, =.
Students will add two-digit numbers without regrouping, using place value understanding and written methods.
Students will subtract two-digit numbers without regrouping, applying place value concepts.
Students will add two-digit numbers that require regrouping ones into a ten.
Students will subtract two-digit numbers that require regrouping a ten into ones.
Students will develop mental addition strategies including counting on, adding tens, and using known facts.
Students will develop mental subtraction strategies including counting back, subtracting tens, and using number bonds.
Students will solve one-step word problems involving addition by identifying key information and writing number sentences.
Students will solve one-step word problems involving subtraction, including "take away" and "how many more" situations.
Students will understand and use ordinal numbers from 1st to 10th to describe position.
Students will identify, describe, and complete simple number patterns involving addition or subtraction of a constant.
Students will explore multiplication as repeated addition and equal grouping, building early multiplicative thinking.
Students will explore division as sharing equally and as halving, laying the groundwork for later division concepts.

02Shapes, Measurement and Data
Exploring two-dimensional and three-dimensional shapes, developing measurement skills using non-standard units, and representing and interpreting data in picture graphs.
Students will identify and name circles, triangles, squares, and rectangles in their environment.
Students will describe 2D shapes by the number of sides and corners (vertices) they have.
Students will identify and name cubes, cuboids, spheres, cylinders, and cones in their environment.
Students will describe 3D shapes using the terms faces, edges, and vertices.
Students will identify, describe, and continue repeating patterns made from shapes, colours, and sizes.
Students will compare the lengths of two or more objects directly using the terms "longer", "shorter", and "about the same length".
Students will measure and compare lengths using non-standard units such as cubes, paper clips, or hand spans.
Students will compare the masses of objects directly and using a balance scale, using the terms "heavier", "lighter", and "about the same mass".
Students will measure mass using non-standard units on a balance scale.
Students will compare the capacity of containers using direct comparison and non-standard units such as cups or scoops.
Students will learn the names and order of the days of the week and relate them to everyday routines.
Students will learn the names and order of the twelve months of the year and connect them to seasons and events.
Students will read and show time to the hour on analogue and digital clocks.
Students will read and show time to the half hour on analogue and digital clocks.
Students will read a monthly calendar to find days, dates, and the number of days in a month.
Students will identify Singapore coins (5¢, 10¢, 20¢, 50¢, $1) and notes ($2, $5, $10) by their appearance and value.
Students will count a collection of coins and notes to find the total amount of money.
Students will solve simple word problems involving buying items and receiving change.
Students will read simple picture graphs where one picture represents one object, and answer questions about the data.
Students will collect simple data through surveys and represent it in a picture graph.
Students will interpret data in picture graphs by comparing categories and answering "how many more/fewer" questions.
Students will explore line symmetry by folding and identifying shapes that are symmetrical.
Students will use positional language (left, right, above, below, in front, behind, next to) to describe the position of objects.
Students will combine 2D shapes to make new shapes and separate shapes into smaller shapes.
Comprehensive review of all topics covered in the year, connecting numbers, shapes, measurement, and data through playful problem-solving activities.
