LESSON 43 SYNOPSIS (12 October – 18 October 2026)

14 October 2026

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.

Primary 1 Lesson 43

Under Select 9, a revision lesson, students consolidate Primary 1 topics through mixed word problems, learning to decide which operation each question needs.

Reinforce multiplication as equal groups and division as sharing equally
Strengthen subtraction with regrouping using part-whole thinking to find a missing part
Practise comparison using “more than” to find the smaller quantity, then the total
Apply two-step thinking to problems combining addition and subtraction
Consolidate place value and money through number clues and counting mixed coins
Apply logical reasoning to order positions from clues
Learn to read a picture graph where each symbol represents 2

Primary 2 Lesson 43

Under Select 13, a revision lesson, students work through mixed Primary 2 problems on length, mass, volume, time, money, graphs and fractions.

Reinforce comparison language (“shorter than”, “longer than”) to find an unknown, then the total
Apply part-whole thinking to find a difference from a given total
Strengthen working backwards to find an amount at first
Practise multi-step problems combining equal groups with an existing quantity
Apply guess and check to find unknowns from a total number of wheels
Consolidate fractions by adding parts of a whole
Practise reading time and finding end times from repeated durations

Primary 3 Lesson 43

Under Select 13, a revision lesson, students apply Primary 3 concepts to multi-step problems drawn from measurement, time, geometry, graphs and money.

Reinforce multiplicative comparison (“three times as many”, “half as many”) across linked quantities
Apply group pricing and unit cost to compare amounts spent or saved
Strengthen proportional reasoning using fixed “for every” relationships
Practise finding a square’s side from a combined perimeter, then building new shapes
Consolidate time by adjusting for clocks running fast or slow
Apply fractions of a metre to find a missing length
Reinforce angles by comparing them with a right angle

Primary 4 Lesson 43

Under Select 14, a revision lesson, students tackle challenging Primary 4 problems combining units, fractions and geometry through structured methods.

Reinforce before-and-after reasoning when quantities change to become equal or multiples
Apply equal units with a known difference to find unknown amounts
Strengthen supposition to find the number of each coin type from a total value
Practise substitution by replacing one quantity with its equivalent
Learn to hold the unchanged quantity constant when a fraction changes
Consolidate area and perimeter of composite figures and paths around rectangles
Reinforce angle properties of rectangles and visualise nets of cubes

Primary 5 Lesson 43

Under Select 16, a revision lesson, students work through demanding Primary 5 problems linking percentage, fractions, volume, area and rate.

Apply excess and shortage reasoning to find the group size and total
Reinforce percentage of the remainder and discount problems across successive stages
Strengthen fraction reasoning to separate the mass of a container from its contents
Practise rate of flow by reading line graphs and linking volume to time
Consolidate area of triangles within rectangles and overlapping shaded regions
Apply units and difference to link several quantities across four boxes
Learn to interpret tiered charges involving “part thereof”

Primary 6 Lesson 39

Lesson 39 is the last lesson for Primary 6 for the 2026 academic year.
