LESSON 7 SYNOPSIS (20 January – 26 January 2025)

19 January 2025

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 7

Understanding the Logic of Addition and Subtraction:

Students will learn how addition and subtraction work within a number statement.
Emphasis will be placed on the relationship between the parts and the whole in a mathematical equation.

Applying the Part-Whole Concept:

Students will explore how the part-whole relationship is used to represent numbers and solve equations.
This will build their understanding of how numbers are connected.

Solving Simple Problem Sums:

By integrating the concepts of number bonds, addition, and subtraction, students will solve simple problem sums.
This step brings together the skills learned, allowing students to apply their understanding in practical scenarios.

Primary 2 Lesson 7

This week, your child will be learning one of the most common problem sums concepts in Primary 2: the concept of :

Comparison by quantity and
Comparison by units.

These two concepts may seem similar, and it is common for students to confuse them. We have intentionally placed these two concepts in the same lesson to help your child understand the fine difference between them.

We believe that by learning these concepts in tandem, your child will have a better understanding and be able to apply them correctly in problem solving.

Primary 3 Lesson 7

Division with Grouping and Remainder:

Students will learn how to divide a larger value into smaller groups, taking into account scenarios involving remainders.
We will explore two main variations:
- Grouping with Remainder that Needs to Be Considered – where the remainder plays a role in the problem’s solution.
- Grouping with Remainder that Can Be Ignored – where the remainder does not affect the final outcome.

Introducing the Concept of Grouping Differences:

Students will be introduced to problems involving grouping differences, which require comparing groups formed by division and understanding their variations.

Primary 4 Lesson 7

External Transfer: Unchanged Difference
- Students will focus on the third variation of external transfer problems, which involves scenarios where the difference between quantities remains unchanged after the transfer.
- This variation is the most commonly tested of the three types and will be explored through problem sums to reinforce understanding and application.
Introduction to Internal Transfer
- Students will be introduced to the related concept of Internal Transfer, where quantities are transferred within the same group or system.
- This concept will help students recognize the differences and connections between external and internal transfer scenarios.

Primary 5 Lesson 7

In this lesson, we will introduce students to Remainder Theory Concepts and its various variations, building on their understanding of the Part and Whole concept.

Understanding Remainder Theory:
- Students will learn how Remainder Theory extends the Part and Whole concept, providing a systematic way to handle problem sums involving remainders.
Preferred Approach – Model Method:
- While some learning centres advocate for the branching method to solve such questions, we believe that the model method is a more effective approach.
- The model method allows students to visualise the problem more clearly, making it easier to understand and solve.
- This approach aligns with what students learned in Primary 4 and mirrors the techniques taught in their schools, ensuring consistency and reinforcing their foundational skills.

Primary 6 Lesson 7

Last week, students successfully completed learning the concept of Ratio Involving Quantity Transfer. This week, they will begin exploring the more advanced concept of Proportion Transfer.

Key Features of the Lesson:

Understanding Proportion Transfer:
- Students will learn how proportion transfer questions differ from quantity transfer questions, with a focus on the added complexity these problems present.
Systematic Data Recording:
- To simplify the complexity of proportion transfer questions, students will be taught systematic methods for recording and organizing data.
- This structured approach will help students break down and interpret the questions, making them easier to solve.
