LESSON 32 SYNOPSIS (27 July – 2 August 2026)

27 July 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 32

This lesson is a revision unit under Select 6, consolidating the range of skills Primary 1 students have built across the year. Students revisit reading data, comparing numbers, and solving multi-step word problems, learning to choose the right approach for each problem type rather than following a single fixed method.

Practise reading and interpreting picture graphs and tables to extract, compare, and order information
Strengthen number comparison, working with “greater than”, “less than”, and forming numbers within a given range
Apply more than / fewer than reasoning to find unknown quantities in word problems
Reinforce multi-step thinking, adding and subtracting across two or three steps to reach a final answer
Consolidate part-whole reasoning to split a total into unequal shares from a stated difference

Primary 2 Lesson 32

This lesson builds foundation in Fractions 3, moving students beyond naming simple fractions into problems where a whole is cut, then cut again. They learn to track what each piece represents when sharing continues in stages.

Learn to work backwards from a part to find the missing whole when a figure is further divided
Apply fraction of a part reasoning, following a piece that is repeatedly shared to find its final value
Practise reading multi-step sharing stories and translating each cut into an equal parts picture
Strengthen the total concept, finding an unknown total from indirect clues rather than a stated figure
Consolidate part & whole and total thinking together within a single problem
Reinforce careful step-by-step working so no cut or share is missed

Primary 3 Lesson 32

This lesson builds foundation in Measurement 5, where students solve length problems by treating quantities as units rather than fixed numbers. They work with two amounts that change through adding or using, and reason about what is equal before or after the change.

Learn to represent “times as much” comparisons using equal units on a bar model
Apply working forward to track how each quantity changes when both sides gain or lose
Practise finding the starting amount when the two quantities become equal in the end
Strengthen the link between a unit and its actual value to unlock the full answer
Reinforce working backwards, undoing each step to recover the original group
Consolidate careful setup so every change is placed correctly before solving

Primary 4 Lesson 32

This lesson builds foundation in Decimals 5, where students solve word problems involving decimal amounts that change through removing or transferring. They reason about the relationship between two quantities before and after the change, working in units rather than raw decimal figures.

Learn to model decimal-quantity problems using equal units and a bar model
Apply working forward to track how each amount shifts after an outward transfer
Practise solving when the two quantities become equal, or one becomes a multiple of the other
Strengthen handling of both inward and outward transfers within the same problem
Reinforce finding the change by first working out the final groupings
Consolidate accurate decimal computation once the unit structure is set

Primary 5 Lesson 32

This lesson builds foundation in Geometry 1, where students learn the core angle rules that underpin all later geometry work. They move from single angle facts to figures that combine several rules, learning to justify each step rather than guess.

Learn the base rules: angles on a straight line, angles at a point, and vertically opposite angles
Apply these rules to find unknown angles in figures with intersecting lines
Introduce the types of triangles and the property that a triangle’s angles sum to 180°
Practise the special properties of equilateral and isosceles triangles to find missing angles
Strengthen multi-step reasoning by combining triangle facts with straight-line and point rules
Reinforce clear working, stating the rule used at each stage

Primary 6 Lesson 32

This lesson is PSLE Revision 4, a mixed-topic revision unit that pulls together the full range of Paper 2 problem types. Students practise recognising which method a question calls for and applying it under exam-style conditions, rather than working through one topic at a time.

Apply geometry rules to construct and measure figures on a grid, and find area involving circles
Strengthen rate and volume reasoning through multi-tap tank problems with different fill and drain rates
Practise complex ratio problems where the shares change depending on who pays
Apply percentage and GST reasoning to pie-chart data and shopping-cost questions
Reinforce rate of work thinking to combine two people’s output on a shared task
Consolidate number properties such as factors within a worded context
