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.

Primary 1 Lesson 24

This lesson builds foundation in Numbers to 40 L3, developing students’ ability to identify part-whole relationships and solve one-step word problems involving addition and subtraction within 40.

Learn to distinguish between parts and whole across real-world groupings such as animals, children, and objects
Introduce the part-whole model as a structured framework for understanding how quantities relate to each other
Apply the finding the whole strategy by combining two known parts using addition
Apply the finding a part strategy by subtracting one known part from the whole
Practise identifying what is being asked before selecting the correct operation
Strengthen column addition and subtraction within 40 through guided working

Primary 2 Lesson 24

This lesson builds foundation in Money 1, introducing students to the Singapore dollar system and developing fluency in reading, writing, and converting monetary values.

Learn to express money values in both dollar notation and words, moving between formats accurately
Practise comparing and ordering amounts in mixed formats (dollars, cents, and cent notation) using ascending and descending order
Apply conversion between dollars and cents in both directions, including decomposing values into dollars and cents components
Strengthen understanding of denominations by calculating equivalent values and switching between coin and note combinations
Introduce logical elimination to find the correct combination of two items totalling a given amount
Apply the part-whole concept to money word problems involving change, shortfall, and total cost

Primary 3 Lesson 24

This lesson builds foundation in Fractions 2, developing students’ ability to interpret and express fractions using the part-whole model across increasingly complex visual and structural contexts.

Learn to identify a fraction as part of a whole by reading shaded regions within a given shape
Apply further cutting of parts to express the same fraction with a smaller unit, building flexibility in visual reasoning
Strengthen understanding of changing denominators by recognising equivalent representations when the whole is re-divided
Introduce comparison of quantities involving part-whole relationships, requiring students to determine a fraction of a set from given conditions
Practise moving from concrete visual models to abstract fraction notation across all four concept types

Primary 4 Lesson 24

This is a revision lesson. Select 5 consolidates mixed P4 topics, training students to switch between methods across problem types rather than applying a single strategy.

Consolidate factors and multiples by finding common factors and working with multiples in two-step calculations
Reinforce rounding skills, including identifying the largest and smallest possible values within a rounding range
Apply fraction as quantity to extract a numerical value from a given fractional relationship
Strengthen before-after comparison using the equal units strategy for problems where ratios change after a transfer
Practise grouping problems requiring systematic organisation of repeated conditions to find a total
Reinforce simultaneous conditions involving two unknowns with a given difference and total value
Apply bar graph interpretation to multi-step problems involving calculations across data points

Primary 5 Lesson 24

This lesson builds foundation in Rate 2, developing students’ ability to connect flow rate with volume across increasingly complex problem structures.

Apply rate involving volume by converting a given flow rate to calculate the time needed to fill a tank of known dimensions
Strengthen the total rate concept by combining two simultaneous taps to determine the resulting water level after a fixed duration
Introduce the difference in rate structure, where one tap fills and another drains, requiring students to identify the net rate before solving
Reinforce unit conversion between millilitres, litres, and cubic centimetres within multi-step calculations
Apply rate with graphs to extract and interpret flow rates from line graphs, including projection beyond the given data range

Primary 6 Lesson 24

This lesson builds foundation in Average 1, developing students’ ability to work with averages flexibly — not just computing them, but reasoning backwards from them to find totals, subgroup values, and unknown quantities.

Learn to calculate average from a given set of values, including cases where the total must first be derived from mixed denominations or indirect relationships
Apply the total from average method to reconstruct group sums and solve multi-step problems
Strengthen average from combined groups by computing a unified average across two sets with different group sizes
Introduce finding a subgroup value by comparing averages before and after a change in group membership
Practise logical reasoning about averages using the True/False/Not Possible to Tell format — a known PSLE question type
Reinforce non-average heuristics through revision problems involving volume, equal sharing, and supposition
