At Matrix Math, we ensure that each lesson is designed to build confidence and mastery in math, preparing students for success in both school and beyond.

Primary 1 Lesson 29

This lesson strengthens Numbers to 100 L3, focusing on comparison-of-quantity problems where students must work out an unknown quantity using given differences.

Learn to find the bigger group when the smaller quantity and the difference are known
Learn to find the smaller group when the bigger quantity and the difference are known
Practise finding the difference directly between two given quantities
Apply reasoning to decide whether to add or subtract based on question wording
Strengthen accuracy by selecting the correct question among distractor options
Reinforce checking skills through a spot the mistake activity involving flawed working
Consolidate all three comparison types through a mixed assessment

Primary 2 Lesson 29

This lesson revises Money 4, consolidating money concepts through converting between dollars and cents and solving multi-step word problems involving cost, change, and value.

Practise conversion between dollars and cents in various formats
Apply part-whole reasoning to find combinations of values matching a target sum
Strengthen finding change through repeated part-whole applications
Learn to find total cost indirectly by first working out an unknown unit value
Practise the total concept through repeated multiplication-based application
Apply regrouping once and twice to solve total-cost problems without remainder
Reinforce grouping to find how many items can be bought, ignoring remainder

Primary 3 Lesson 29

This lesson builds foundation in Measurement 2, introducing interval-based reasoning alongside continued work on unit conversion problems.

Apply the total concept by working backward from grouped units to unit value, then multiplying to find a final amount
Learn interval reasoning by finding the distance between two positions when spacing is known
Practise direct work forward, calculating distances directly from a given interval
Introduce work backward thinking, deducing the number of objects from total length and interval
Strengthen repeat application, scaling a known interval up to a larger position
Consolidate reasoning between “number of gaps” versus “number of objects” in interval problems
Reinforce multi-step thinking by combining measurement and money contexts in one problem

Primary 4 Lesson 29

This lesson builds foundation in Decimals 2, applying decimal computation to multi-step word problems that combine cost, measurement, and money contexts.

Apply the part-whole concept to find change after multiple purchases involving decimal prices
Practise indirect repeat application, working out an unknown unit cost after subtracting a known part
Strengthen interval reasoning by scaling a known decimal distance to a different span
Introduce the supposition method, assuming one coin or note type to solve for the other
Reinforce checking answers logically when supposition totals don’t match the given sum
Consolidate decimal subtraction and multiplication across varied real-life contexts
Apply place value understanding to identify the value of specific decimal digits

Primary 5 Lesson 29

This lesson builds foundation in Percentage 1, introducing percentage as a way of expressing part of a whole and applying it across measurement, money, and data contexts.

Learn conversion between fractions, decimals and percentages using multiple methods
Apply percentage reasoning to express one quantity as a percentage of a whole
Practise finding a percentage of a quantity across combined groups
Strengthen the unitary method to work backward from a percentage to an unknown total
Introduce reasoning with pie charts, linking percentage, fraction and actual values
Consolidate multi-step problems combining percentage of remainder with given totals

Primary 6 Lesson 29

This lesson revises PSLE Revision 1, bringing together challenging problem types across number, geometry, and ratio in preparation for the exam.

Reinforce decimal place value and percentage conversion under exam conditions
Apply area and perimeter reasoning to composite figures involving semicircles
Strengthen construction and area-transformation skills using square grids
Consolidate before-after and excess-and-deficit reasoning in multi-step word problems
Apply algebraic representation to solve problems involving unknowns and cost differences
Reinforce percentage change reasoning across ratio and quantity transfer situations
Strengthen structured working under time pressure through varied, unfamiliar question formats
