At Matrix Math, we provide an engaging and detailed learning experience for your child. Matrix Math Tuition programme focuses on essential concepts that will further strengthen their mathematical foundation. The lesson synopsis gives parents a clear preview of the topics and problem-solving skills that will be covered in class. 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.
In Lesson 7, students will strengthen their understanding of addition and subtraction within 10, with a focus on choosing the correct operation and finding missing numbers systematically.
Practise deciding whether to use “+” or “−” based on number relationships
Reinforce the part–part–whole concept to connect addition and subtraction
Learn to find missing numbers in addition and subtraction sentences
Apply strategies such as Total − Part = Part and Part + Part = Total
Solve simple problem sums involving sums and differences within 10
Emphasise solving questions using clear steps and logical thinking, not guessing
This lesson will strengthen students’ number bonds, operation sense, and reasoning skills, building a strong foundation for more complex word problems in later topics.
In Lesson 7, students will learn to solve comparison word problems using the unit model method, focusing on relationships such as more than, fewer than, twice, and thrice.
Introduce comparison problems involving part–whole relationships and quantity differences
Learn to represent information using units to compare two or more groups
Practise solving problems where one group has more or fewer items than another
Apply multiplication ideas such as twice as many and thrice as many using units
Solve word problems where the total is given, and students need to find individual parts
Emphasise removing known parts and the “extra” before finding the unknown value
In Lesson 7, students will learn to solve grouping and sharing word problems using division, with a focus on understanding and handling remainders correctly.
Introduce grouping problems where the remainder is ignored (e.g. rewards, free items)
Practise grouping problems where the remainder must be considered (e.g. buses, rooms, trips needed)
Learn to interpret the meaning of the remainder based on the context of the question
Apply division to difference-type problems, where an difference per group is given
Reinforce the use of clear step-by-step reasoning instead of guesswork
In Lesson 7, students will learn to solve advanced word problems involving transfer and comparison, using model drawing and unit comparison to track changes accurately.
Introduce external transfer problems where the difference remains unchanged after equal amounts are added or removed
Practise solving age, money, length, and quantity problems using unit comparison (e.g. twice, thrice, four times as much)
Learn to identify and apply the correct strategy for unchanged difference situations
Introduce internal transfer problems where the total remains unchanged, focusing on redistribution between groups
Reinforce the habit of analysing before–change–after systematically to avoid common mistakes
This lesson will strengthen students’ algebraic thinking, logical reasoning, and problem-solving accuracy, which are key skills for tackling more complex multi-step word problems in upper primary.
In Lesson 7, students will learn to solve fraction and unit-model word problems involving remainders, focusing on identifying the correct remainder strategy for different problem types.
Introduce remainder concept (basic) using unit models and LCM to find the smallest valid total
Practise problems where the value of a part is given, and students work backwards to find the total
Apply the remainder concept to situations involving money, quantity, and measurements
Learn to solve problems where the value of the difference is given, using unit comparison
Reinforce choosing the correct model and steps before calculating, to avoid common errors
This lesson will strengthen students’ fraction sense, algebraic thinking, and multi-step problem-solving skills, which are essential for higher-level fraction and heuristic questions in Primary 5.
In Lesson 7, students will strengthen their understanding of percentage concepts and apply them to multi-step word problems involving real-life contexts.
Revise and apply percentage increase and decrease, including interpretation of graphs
Solve problems involving discounts, successive discounts, and GST
Learn to work backwards to find original values from given percentage changes
Apply percentage concepts to ratio, comparison, and difference-based problems
Practise analysing problems carefully to decide the correct percentage base before calculating
This lesson will strengthen students’ conceptual understanding of percentages, accuracy, and exam-readiness, which are critical skills for tackling higher-level PSLE percentage and data-interpretation questions.
