5P3 Lesson 2
This week (Lesson 2), we will continue with Whole Numbers 2.
This week we will focus on multiplications.
> Concepts of multiplications
> Operations involving 1 digit x 2 digits
> Place values up to hundreds.
-
6P3 Lesson 3
This week (Lesson 3), we will continue with Whole Numbers 3.
This week we will be introducing Long Division. Every year, students will struggle with this lesson. Long division requires students to be good at multiplication and division.
In this lesson, we aim to introduce the mechanics of long division to the children. The long division consists of *4 steps*. We have created a *video* of how long division will be taught to the children. The video is available at online.matrixmath.sg.
We expect most of the children to struggle with this week's homework. Please do not be too worried. Every year, students will face the same struggle. We will encourage them. Give them time to slowly "digest" the long division mechanics. It may take several lessons, and they will ultimately get it. We will be repeating this to the children every week.

7P3 Lesson 4
This week (Lesson 4), we will continue with Whole Numbers 4.
This week we will build on the concepts taught in Lesson 3. We will be covering two concepts. Namely, "Listing method" and Total concept."
The listing method: This is a common technique used to solve problem sums by logically listing possible answers.
The Total concepts: This is a fundamental problem sums concept involving multiplication and division. In this lesson, the students will learn long-division problem sums involving remainders.
This week is the last lesson for 2022. We will like to take this opportunity to wish all parents and students a Merry Christmas and a Happy New Year!
-
8P3 Lesson 5
This week (Lesson 5), we will continue with Whole Numbers 5.
We will cover 3 commonly tested concepts.
- Grouping considers Remainder.
- Grouping ignores Remainder.
- Difference concepts
We will teach the students how to handle "Remainders" in questions requiring Grouping. An important takeaway from this lesson is to understand under what setting should "Remainder" be considered and or ignored.
-
9P3 Lesson 6
This week we will be continuing our work on Whole Numbers with Lesson 6. One of the main topics we will be covering is the supposition method, which was introduced to your children in Primary 2 using diagrams. In this lesson, we will be focusing on how to solve problems using this method without the aid of diagrams.
Additionally, we will be revisiting the concept of "comparison of quantities," including two subtopics: comparison of quantities with a given group and difference, and comparison of quantities with a given total and difference. These are fundamental concepts that will be useful in solving more advanced problems, and we will be revisiting them in future lessons.
-
10P3 Lesson 7
This week, in Lesson 7, your child will be continuing on from the problem sums concept of comparison by quantity which they were taught last week.
Closely related to this concept is comparison by units. We will be covering this concept in depth, including the 3 variations in which it can be tested in Primary 3. This will help your child to have a better understanding and be able to apply these concepts correctly in problem solving.
-
11P3 Lesson 8
In the coming week, the children will be continuing with lesson 8 on Whole Numbers. As a reminder, this week we covered the concepts of "comparison of quantities" and "comparison of units." Next week, we will be challenging the students by incorporating these concepts into a single question, which is not something typically covered in other schools.
We will also be giving the children opportunities to practice their model drawing skills. Additionally, we will be introducing problem sums that involve "working forward" which will require the use of higher-order model drawing methods. This is a more advanced method of solving mathematical problems, and it's a great way to enhance their problem-solving skills.
Please let us know if you have any questions or concerns.
-
12P3 Lesson 9
This week (Lesson 9) and the next, we will revise all the concepts we have taught. In this revision lesson, we will focus on
- 4 Operations
- Forming numbers
- Listing methods
- Total concepts
-
13P3 Lesson 10
This week (Lesson 10), we will continue to revise the concepts taught in previous lessons. The concepts we will cover are as follows:
> 4 Operations
> Problem sums involving multiplications and divisions.
> Grouping (consider/ignore remainder)
> How to use differences to solve problem sums
> Supposition method
-
14P3 Lesson 11
This week, your children will be starting their journey with Money. They will learn the following essential concepts:
- Converting money into different denominations.
- Basic arithmetic operations with money.
- Solving problem sums that require finding the right combination of different monetary denominations.
This lesson will provide a necessary foundation for solving problem sums involving money.
-
15P3 Lesson 12
We will be covering four concepts that are commonly applied in the topic of Money.
These will include:
- Total Concept - Repeat Application for 2 times
- Total Concept - Repeat Application for 3 times
- Total Concept - Regrouping
- Total Concept - involves Part and Whole
We have included graphics to help your child understand the logic behind these concepts and enhance their learning experience.
Please do not hesitate to contact us if you have any questions or concerns.
-
16P3 Lesson 13
In this week's lesson (Lesson 13), we will continue with Money lesson 3. In this lesson, we will cover three concepts:
- Total Concept - Indirect
- Grouping - Ignore the remainder
- Supposition method
Concept 2 is a common way problem sums relating to the Topic "Money" are tested.
Concept 3 is the Supposition Method. Students will have some impression of this concept as we have taught introduced it during "Whole Numbers". We understand that this concept is not easy for most students. We will be repeating this concept in future lessons.
-
17P3 Lesson 14
This week (Lesson 14), we will continue with Money lesson 4.
The concepts we will cover include
1. Comparison of quantity
2. Comparison of units
In this lesson, we will be exposing the children to the different ways “comparison of units” questions can be tested.
-
18P3 Lesson 15
This week (Lesson 15), we will continue with Money lesson 5.
Last week we learnt the comparison of quantity and comparison of units. This week we will be combining these two concepts.
Children may find this lesson more challenging as the models required will be more complex.
In addition, we will be introducing stacking model concepts in this lesson.
-
19P3 Lesson 16
This week (Lesson 16), we will continue with Money lesson 6.
We will cover 3 concepts.
1. Quantity Value
2. Equivalent equation
3. Forming number statements
Quantity value is a very commonly tested concept. Money is a measure that has both quantity and value. For example, ten 5-cent coins have a quantity of 10 but a value of 50 cents.
Concepts 3, trains students to form number statements involving 2 unknowns and solve them through association and comparison.
