For many primary school students, multiplication can feel overwhelming. Some struggle to recall their multiplication facts, others lose track when working with multi-digit numbers, and many find long multiplication with regrouping especially intimidating. Parents share these concerns too, since multiplication is the foundation for key areas in the national curriculum, including division problems, fractions, percentages, and even algebra later on.
But multiplication is not just about memorising the times table — it’s about truly understanding the process, knowing when to regroup, and applying those skills confidently in both sums and word problems. This guide will walk you through the essentials of math multiplication workings, from simple repeated addition to tackling regrouping and long multiplication. By the end, you’ll have a clear strategy to help your child practise effectively and master multiplication with confidence.

Why Multiplication Matters in Primary Maths
Multiplication is more than just a way to speed up repeated addition — it is a key problem-solving skill that underpins much of the English national curriculum in mathematics. For example:
Primary multiplication forms the basis for later division problems.
Understanding regrouping helps with more complex place value operations, like decimals.
Word problems involving the total number of objects often rely on multiplication.
Mastering multiplication ensures children are equipped not just for school exams, but for everyday calculations and more advanced maths topics.
Building a Strong Foundation: Multiplication as Repeated Addition
Before diving into more complicated workings, children should first understand that multiplication is simply repeated addition. For example:
3 × 4 means “3 groups of 4,” which is the same as 4 + 4 + 4 = 12.
Similarly, 5 × 6 is “5 groups of 6,” or 6 + 6 + 6 + 6 + 6 = 30.
This concept is best introduced through times tables games, arrays, or real-life scenarios (like grouping pencils, sweets, or building blocks). Once students are comfortable, they can begin memorising the multiplication table to improve speed and accuracy.
What Is Multiplication Without Regrouping?
This occurs when no carrying over (regrouping) is required because each digit multiplies neatly without producing a number greater than 9.
In multiplication, we always start with the ones, then move on to the tens, and finally the hundreds.
Example
What is the answer when 21 × 3?
Solution:
What Is Multiplication With Regrouping?
This happens when you need to carry over a number because the product of two digits is 10 or greater.
In such cases, regrouping is required during the multiplication process.
Example:
What is the answer when 526 × 3?
Multiplying a 3-digit Number by a 2-digit Number
When multiplying a 3-digit number by a 2-digit number, we break the 2-digit number into tens and ones, then multiply in parts.
Example
What is the answer when 326 × 24?
Common Mistakes in Multiplication Workings
Parents often see their children make the same errors repeatedly. Here are a few common pitfalls in math multiplication:
Forgetting to regroup correctly.
Writing numbers in the wrong place value column.
Adding wrongly after regrouping.
Choosing the wrong operation in word problems (multiplying when they should divide).
To overcome these issues, consistent practice and careful checking of the final answer are essential.
Using Multiplication to Solve Word Problems
In the PSLE and other assessments, students are often tested on multiplication within real-world contexts. For instance:
“A school has 45 students in each class. If there are 12 classes, what is the total number of students?”
Here, students must recognise that the problem involves multiplication (45 × 12) rather than addition or subtraction. Developing this problem-solving skill is just as important as getting the mechanics of multiplication correct.
Practice Makes Perfect: Daily Multiplication Drills
To truly master multiplication, students need daily exposure. A few minutes each day is far more effective than cramming before an exam. Here’s a simple routine:
Revise one times table daily.
Solve a mix of multiplication with regrouping and without regrouping problems.
End with one or two word problems.
This approach ensures students can not only compute answers but also apply multiplication to different scenarios.
The Importance of Checking the Final Answer
After completing a problem, students should always double-check their final answer. Did they regroup correctly? Did they add the partial results properly? Does the answer make sense in the context of the problem?
For example, if the question involves counting the total number of seats in a bus, and the final answer is in the thousands, students should pause to consider whether it’s reasonable. This habit of estimation and reflection prevents careless mistakes.
Mastering math multiplication workings is not about rushing through worksheets — it’s about building a deep understanding of concepts like repeated addition, regrouping, and place value, while also gaining speed and accuracy with the multiplication table.
By combining daily practice, real-world application, and strategies for both simple and complex problems, students can confidently handle everything from multiplication without regrouping to advanced long multiplication with multi-digit numbers.
