Primary 1 Lesson 27

This lesson introduces Numbers to 100 L1, building foundational fluency with two-digit numbers through counting, reading, comparing, ordering, and computing within 100. Students move from recognising quantities to working with number relationships and basic operations.

Practise counting and matching quantities to numerals up to 100
Strengthen recognition of number words and correct spelling of two-digit numbers
Learn comparing two numbers using greater and smaller, building sense of magnitude
Apply ordering and sequencing skills by arranging numbers and identifying neighbours
Reinforce understanding of number patterns by identifying rules in counting sequences
Practise addition and subtraction within 100 using structured methods
Consolidate through challenge problems requiring multi-step reasoning with missing values

Primary 2 Lesson 27

This is a revision lesson under Select 8, reinforcing problem-solving across the four operations, measurement, and multi-step word problems. Students revisit key P2 concepts through increasingly complex questions that demand careful reading and structured thinking.

Reinforce multiplication and division fluency through missing number and pattern-based equations
Practise interpreting grouping language and writing matching multiplication equations
Apply multi-step reasoning to word problems combining multiplication, division, and subtraction
Strengthen comparison skills using difference and multiples relationships across two-part problems
Consolidate equal sharing and equal grouping strategies in context-based scenarios
Learn to work with mass comparison using balance diagrams and logical reasoning
Practise time conversion between minutes, hours, and reading clocks accurately

Primary 3 Lesson 27

This lesson advances understanding in Fractions 3, training students to solve fraction word problems using structured models. The focus shifts from basic fraction identification to applying fractions within multi-step problem contexts.

Learn to use the part-whole model to find a fraction of a part when the denominator changes
Practise solving fraction of a fraction problems involving further cutting or subdivision
Apply comparison of units to relate fractional parts back to the whole in multi-part scenarios
Strengthen the link between fractional language and division reasoning within word problems
Introduce proportion transfer forward, working step-by-step through sequential operations to find a remaining group
Consolidate structured working by combining fraction computation with addition and subtraction in context

Primary 4 Lesson 27

This is a revision lesson under Select 8, integrating P4 problem types that require students to identify relationships, set up models, and apply structured methods across varied contexts including money, fractions, and patterns.

Reinforce equal units reasoning in problems involving multiples and group relationships
Practise excess and shortage strategies to find unit cost from two purchasing scenarios
Apply comparison models to multi-step problems combining difference and total
Strengthen pattern recognition by identifying rules and extending to larger terms
Consolidate fraction of a whole thinking when quantities are built through comparison
Learn to solve equal value problems by grouping different items into combined units
Apply simultaneous comparison to find individual costs from two sets of purchases

Primary 5 Lesson 27

This lesson deepens problem-solving in Whole Numbers & Fractions 6, training students to handle exchange, listing, and proportion-based comparison problems — key PSLE word problem structures requiring systematic reasoning.

Learn the difference concept with exchanging, solving problems where items are swapped at a given rate to find original quantities
Practise setting up exchange equations by identifying the net gain per item and working from total differences
Apply systematic listing to find the least quantity satisfying pack-size constraints with a given difference
Strengthen proportion comparison by using fraction relationships to find individual quantities when the total is given
Consolidate proportion comparison given difference, linking fractional parts to the difference between two quantities
Reinforce choosing between total-based and difference-based approaches depending on what information the problem provides

Primary 6 Lesson 27

This lesson tackles Area and Perimeter at PSLE level, training students to deconstruct complex composite figures and apply structured methods to find unknown dimensions, areas, and perimeters across challenging configurations.

Learn to decompose composite figures into known shapes — rectangles, triangles, squares, and trapeziums
Apply perimeter tracing to identify hidden lengths within overlapping or combined shapes
Practise using area relationships between shaded and unshaded parts to find missing dimensions
Strengthen reasoning with identical shape properties, using equal sides and symmetry to set up equations
Consolidate folding problems, connecting the folded triangle’s area back to the original rectangle
Reinforce solving for unknowns using perimeter and area simultaneously as two linked conditions
Apply structured working to multi-shape constructions where dimensions depend on each other
