Let’s delve into each area to gain a better understanding of the concepts you’ll explore.
Number and Place Value
In Year 6 maths, you’ll build upon your understanding of numbers and their place value. You’ll discover the power of expanded notation, which allows you to express numbers using place values. For example, the number 527 can be expanded to 500 + 20 + 7. Understanding expanded notation helps you comprehend the value of each digit in a number.
You’ll also learn to round numbers to the nearest hundred, thousand, ten thousand, and beyond. Rounding helps simplify large numbers, making them more manageable for estimation and mental calculations.
An exciting concept introduced in Year 6 is working with positive and negative numbers. These numbers indicate direction, gain, or loss. For example, if you have $50 and spend $30, you can represent the transaction as +50 – 30 = +20, where positive values represent money gained and negative values represent money spent. What could be -50 + 30? Any idea?
Another intriguing aspect of number and place value is prime and composite numbers. Prime numbers are those that have exactly two factors: 1 and the number itself. Composite numbers, on the other hand, have more than two factors. Understanding these concepts lays the foundation for exploring higher-level mathematical concepts.
Grab a piece of paper and see how quickly you can find all prime numbers less than 100.
In Year 6, you’ll also encounter the highest common factor (HCF) and lowest common multiple (LCM). HCF is the largest number that divides two or more numbers without leaving a remainder, while LCM is the smallest multiple shared by two or more numbers. These concepts are valuable for simplifying fractions and solving various mathematical problems.
Fractions and Decimals
Fractions and decimals play a significant role in our everyday lives, and Year 6 is the perfect time to deepen your understanding of these concepts.
Adding and subtracting fractions with unlike denominators is a skill you’ll master in Year 6. When the denominators of two fractions are different, you need to find a common denominator before performing the operations. For example, to add \(\frac{1}{3}\) and \(\frac{2}{5}\), you’d find a common denominator of 15 and rewrite the fractions as \(\frac{5}{15}\) and \(\frac{6}{15}\), respectively. Then, you can add them to get \(\frac{11}{15}\).
You’ll also explore finding a fraction of a whole, which helps you understand how fractions represent parts of a whole.
As you continue to explore year 6 maths problem solving techniques, you’ll extend your knowledge of decimals by multiplying and dividing decimal numbers by powers of 10 mentally. This technique involves shifting the decimal point to the left or right based on the given power of 10. For example, to multiply 0.35 by 100, you move the decimal point two places to the right, resulting in 35. Similarly, dividing 0.72 by 10 would require shifting the decimal point one place to the left, resulting in 0.072.
Multiplying two decimal numbers is another skill you’ll develop. You’ll learn to multiply the numbers as if they were whole numbers and then adjust the decimal point based on the total number of decimal places in both factors. For example, to multiply 2.4 by 0.6, you’d ignore the decimal points and multiply 24 by 6 to get 144. Since the original numbers had a total of two decimal places, the product should have two decimal places as well. Therefore, the result is 1.44.
Money and Financial Mathematics
Money matters! Year 6 maths equips you with the necessary skills to navigate financial scenarios and make informed decisions.
In certain situations involving money, finding an exact answer is crucial. For instance, when you’re paying at a store, you need to calculate the exact amount owed. On the other hand, in some situations, an approximation is sufficient. Let’s say you have $100 in your pocket and want to buy four items priced at $16.25, $8.55, $10.60, and $5.50. By simply eyeballing the figures, you can estimate that you have more than enough money to buy all four items. In such cases, finding the exact sum of money needed may not be necessary.
Year 6 also introduces financial planning for events or situations that require careful consideration of factors such as the total amount of money to be raised, the available time, and the number of people involved. Imagine organizing a fundraising event for a school trip. You need to determine the total amount of money required, how long you have to raise it, and how many people will contribute to cover the costs. Financial planning helps you manage resources effectively and achieve your goals.
Patterns and Algebra
Patterns are everywhere, and Year 6 maths enables you to recognize, describe, and extend patterns to uncover algebraic relationships.
You’ll explore number patterns, where you identify and extend sequences based on a rule. For example, in the sequence 5, 8, 11, 14, 17, …, the rule is to add 3 to each term (number) to obtain the next one.
You will also learn about balancing scales, which is a fun and intuitive way of solving equations – a topic that will be a part of your life for years to come!
Using Units of Measurement
Measurement plays a fundamental role in our lives – a cricket pitch must be of a specific length, we need to measure mass at the grocery store, and juices and various other liquid cans have fixed capacities.
In the metric system of units, each unit is 10 times more than its previous smaller unit. The ones that you need to know and remember are:
Length – millimetre (mm), centimetre (cm), metre (m) and kilometre (km).
Mass – milligram (mg), gram (g) and kilogram (kg).
Capacity or Volume – millilitre (mL), litre (L) and kilolitre (kL).
Converting between different units within each measurement category is an essential skill. For example, you’ll learn to convert kilometres to metres, grams to kilograms, millilitres to litres, and so on. Remember, when adding and subtracting quantities expressed in different units, you must first have them all in the same unit. Only then can you do the maths.
For example, 1.3 kg + 99 g = 1,300 g + 99 g = 1,399 g

Shapes
It is crucial that you have a good idea about shapes, as that forms the basis of geometric reasoning.
A polygon is a closed shape with straight sides. What is the minimum number of sides a polygon can have?
A polygon may be regular or irregular. In a regular polygon, all the sides are of the same length and all the angles have the same degree measure. What’s the simplest regular polygon you can think of?
Polygons are named based on the number of sides (or angles) they have, such as quadrilateral, pentagon, hexagon, and so on.
You also learn about line and rotational symmetry, parts of a circle, the classification of triangles, and the triangle angle sum property, which states that the sum of the angles in any triangle equals \(180^{\circ}\).
Location and Transformation
Year six maths introduces you to the idea of the coordinate plane formed by the x and the y axes – two number lines that cross each other at 0. Then, the location of any point on the plane can be described as an ordered pair of numbers (x, y) where the first number represents the number along the horizontal axis (x-axis) and the second number represents the number along the vertical axis (y-axis). The coordinate plane is divided into four quadrants as shown in the figure below.
You will also learn about the different forms of transformations – translation, rotation, reflection and dilation (scaling).
Geometric Reasoning
This one is about angles and other stuff. You will learn about the types of angles – right, acute, obtuse, straight, reflex, how to name and refer to an angle, complementary and supplementary angles, angles at or around a point (they add up to \(360^{\circ}\)), and vertically opposite angles.
Chance
Probability or ‘chance’ is a very interesting topic to explore! In year six, it all starts with simple events (things that occur) such as tossing a coin, rolling a die, randomly choosing a card from a standard deck and making simple predictions. As you grow up, you come across more challenging problems related to probability.
Data Representation and Interpretation
The last topic we cover is related to representing and interpreting data. Data is all around us, more than ever before! Understanding how to draw and read line graphs, bar graphs, picture graphs, pie charts and double-line graphs will help you visualize data in a meaningful way. You will also learn how to answer simple questions related to such graphs.
