Number Patterns and Rules – Standard 3 Maths

What you will learn

  • Describe a number pattern and say its rule.
  • Continue a pattern, find missing numbers and spot mistakes.
  • Make your own number pattern and explain its rule.

Patterns are everywhere: in hopscotch squares, in the steelpan, and in numbers too. A number pattern is a list of numbers that follows a rule. If you know the rule, you can work out any number in the pattern. In this lesson you will become a pattern detective.

What is the rule?

Look at this pattern:

1, 6, 11, 16, 21

To find the rule, look at how you get from one number to the next. 1 to 6 is 5 more. 6 to 11 is 5 more. The rule is start at 1 and add 5. The next number is 26.

Patterns can go down too: 9 000, 8 500, 8 000, 7 500. The rule is start at 9 000 and subtract 500.

Always check the rule works for every step, not just the first one.

Patterns with times tables

Counting in sixes, 6, 12, 18, 24, 30, is a pattern from the 6 times table. The rule is add 6.

Some patterns multiply. In 2, 4, 8, 16, 32 each number is double the one before. The rule is multiply by 2. In 3 200, 1 600, 800, 400 each number is half the one before. The rule is divide by 2.

Worked example

Find the rule and the next number: 5, 10, 20, 40, ___

Show me how

5 to 10 is add 5. But 10 to 20 is add 10, so adding the same number does not work.

Try multiplying: 5 × 2 = 10, 10 × 2 = 20, 20 × 2 = 40. It works every time.

The rule is multiply by 2. The next number is 40 × 2 = 80.

Missing numbers and mistakes

To find a missing number, first find the rule using numbers that are next to each other.

Worked example

Find the missing number: 250, 500, ___, 1 000, 1 250

Show me how

500 − 250 = 250, and 1 250 − 1 000 = 250.

The rule is add 250.

500 + 250 = 750. The missing number is 750.

Sometimes a pattern has a mistake. In 7, 14, 21, 27, 35 the rule is add 7, but 21 + 7 is 28, not 27. The 27 is the mistake.

Watch out! A common mistake

Do not find the rule from only the first two numbers. In 2, 4, 8, 16 the first step is add 2, but the next step is add 4. Check every step before you decide on the rule.

Make your own pattern

To make a pattern, choose a start number and a rule. For example: start at 100 and add 25. The pattern is 100, 125, 150, 175, 200.

When you share your pattern, always say the rule so someone else can check it.

Recap

  • A number pattern follows a rule, such as add 5, subtract 100 or multiply by 2.
  • To find the rule, look at how you get from each number to the next.
  • Check the rule works for every step.
  • Use the rule to find missing numbers and to spot mistakes.
  • To make a pattern, choose a start number and a rule, and always say the rule.

Words to know

pattern
Numbers or shapes that follow a rule.
Example: 2, 4, 6, 8 is a pattern.
rule
What you do to get from one number to the next.
Example: The rule for 2, 4, 6, 8 is add 2.
term
One of the numbers in a pattern.
Example: In 5, 10, 15, the third term is 15.
double
To multiply by 2.
Example: Double 40 is 80.
halve
To divide by 2, or split into two equal parts.
Example: Half of 800 is 400.

Try it at home

  • Look for number patterns at home and outside: house numbers on one side of a street, page numbers, or a calendar. Write down the rule for each one.
  • Mini project: make a pattern poster. Choose three different rules, write the first six numbers of each pattern, and ask someone at home to work out your rules.

Test tips

Tips for class tests

  • Write the jump between each pair of numbers above the pattern before you answer.
  • If adding or subtracting does not work, try multiplying or dividing.
  • Check your answer by using the rule on the number before it.

For parents and teachers

After this lesson, your child should be able to:

  • describe and continue number patterns that add, subtract, multiply or divide;
  • find missing numbers and mistakes in a pattern;
  • make a pattern and state its rule.

Ask your child to say the rule in words (“start at 7 and add 7”). Patterns with fractions are covered later, in the fractions lessons.

Rounding and Estimating – Standard 3 Maths

What you will learn

  • Round numbers to the nearest 10, 100 and 1 000.
  • Use a number line to see which ten, hundred or thousand a number is nearest to.
  • Estimate how many things there are, using a group of 100 as a guide, then count to check.

Sometimes we do not need an exact number. “About 3 000 people came to the show” is easier to say and to remember than “2 963 people came”. A number that is close but easier to use is called a rounded number. In this lesson you will learn how to round and how to make a good estimate.

Rounding to the nearest 10

The number 2 463 is between 2 460 and 2 470. Picture a number line from 2 460 to 2 470. The middle is 2 465.

2 463 is before the middle, so it is nearer to 2 460. We say 2 463 rounded to the nearest ten is 2 460.

What about 2 465, exactly in the middle? The rule is: halfway rounds up. So 2 465 rounds to 2 470.

A quick way: look at the ones digit. If it is 0, 1, 2, 3 or 4, round down. If it is 5, 6, 7, 8 or 9, round up.

Rounding to the nearest 100 and 1 000

To round to the nearest hundred, look at the tens digit. To round to the nearest thousand, look at the hundreds digit. Use the same rule: 5 or more rounds up.

Worked example

Round 5 739 to (a) the nearest 100 (b) the nearest 1 000.

Show me how

(a) 5 739 is between 5 700 and 5 800. The tens digit is 3, which is less than 5. So round down: 5 700.

(b) 5 739 is between 5 000 and 6 000. The hundreds digit is 7, which is 5 or more. So round up: 6 000.

Watch out! A common mistake

When you round, the digits after the place you round to all become zeros. 4 382 rounded to the nearest hundred is 4 400, not 4 482 or 4 480. And remember: 2 650 rounds to 2 700, because halfway rounds up.

Estimating with 100 as a guide

An estimate is a good guess that uses what you know. One useful thing to know is what 100 things look like.

Imagine a jar of red beans. You count 100 beans into a cup. The jar holds about 4 cups. So there are about 400 beans in the jar. This is called mental grouping: in your head, you split the big amount into groups of 100.

After you estimate, you can count to check. If you count 386 beans, your estimate of 400 was very good!

Worked example

A page of a book has about 100 words. A story has 9 pages. About how many words is the story?

Show me how

Each page is about 100 words.

9 groups of 100 is 900.

Answer: about 900 words.

Try it

TRY ITNumber-line rounder

Look at where the number sits on the line. The red mark shows the middle. Tap the end that the number is nearer to.

TRY ITEstimate the dots

The small box has exactly 100 dots. The dots in the long box are packed the same way. Use the small box to estimate how many there are. Then the game counts them to check.

Let’s practise

Work out each one in your copybook. Open Hint if you are stuck, then open Show answer to check your working.

1. Round 3 476 to the nearest 10.

Hint

Look at the ones digit.

Show answer

3 476 is between 3 470 and 3 480. The ones digit is 6, so round up: 3 480.

2. Round 3 476 to the nearest 100.

Hint

Look at the tens digit.

Show answer

The tens digit is 7, so round up: 3 500.

3. Round 3 476 to the nearest 1 000.

Hint

Look at the hundreds digit.

Show answer

The hundreds digit is 4, so round down: 3 000.

4. Round 6 250 to the nearest 100.

Hint

It is exactly halfway between 6 200 and 6 300.

Show answer

Halfway rounds up: 6 300.

5. (a) Round 8 049 to the nearest 10.
(b) Round 8 049 to the nearest 100.
(c) Round 8 049 to the nearest 1 000.

Hint

Each time, look at the digit to the right of the place.

Show answer

(a) 8 050
(b) 8 000
(c) 8 000

6. Which numbers round to 700 when rounded to the nearest 100: 649, 651, 748, 750?

Hint

Recap

  • To round, find the two tens, hundreds or thousands the number is between, and choose the nearer one.
  • Look at the digit to the right of the place you are rounding to. 0 to 4 rounds down. 5 to 9 rounds up.
  • Halfway always rounds up.
  • When you round, the digits after that place become zeros.
  • Knowing what 100 things look like helps you estimate bigger amounts. Count to check your estimate.

Words to know

round
To change a number to a nearby ten, hundred or thousand that is easier to use.
Example: 2 463 rounded to the nearest ten is 2 460.
nearest
The closest.
Example: 5 739 to the nearest thousand is 6 000.
estimate
A careful guess that is close to the real amount.
Example: My estimate was about 400 beans.
benchmark
A number you know well that you use to help you estimate.
Example: We used 100 as a benchmark to estimate the beans.
halfway
Exactly in the middle.
Example: 2 465 is halfway between 2 460 and 2 470.

Try it at home

  • Count out 100 grains of rice, dried peas or beans. Look closely at how much space they take. Then estimate a bigger amount using your 100 as a guide, and count to check.
  • Mini project: look at the prices on a shop receipt or in a flyer. Round each price to the nearest 10 dollars and add up the rounded prices to estimate the total.

Test tips

Tips for class tests

  • Underline the digit you need to look at before you round.
  • Check your answer has zeros after the place you rounded to.
  • For estimates, the question often says “about”. You do not need an exact answer.

For parents and teachers

After this lesson, your child should be able to:

  • round numbers to the nearest 10, 100 and 1 000;
  • explain rounding using a number line;
  • estimate quantities using 100 as a benchmark, and check by counting.

Children often forget that halfway (for example 6 250 to the nearest 100) rounds up, or they change only one digit. Using a drawn number line helps. Everyday estimating (people in a queue, beans in a jar) builds good number sense.

Compare and Order Numbers – Standard 3 Maths

What you will learn

  • Compare numbers up to 10 000 using place value.
  • Use the signs (is greater than) and (is less than).
  • Put numbers in order, and make the largest and smallest numbers from four digits.

Which is higher: El Tucuche or El Cerro del Aripo? Which school has more pupils? To answer questions like these, you need to compare numbers. In this lesson you will learn a sure way to compare any two numbers up to 10 000.

The forested peak of El Tucuche in the Northern Range of Trinidad, with clouds above
El Tucuche is 936 metres high. El Cerro del Aripo is 940 metres high. Which is higher? Photo: bndawn, CC BY-SA 3.0, via Wikimedia Commons.

Comparing with place value

First, count the digits. A number with more digits is greater. 1 001 has four digits and 999 has three, so 1 001 is greater.

If the numbers have the same number of digits, compare the digits from the left, one place at a time, until you find two that are different.

ThHTO
4382
4328

Thousands: 4 and 4 are the same. Hundreds: 3 and 3 are the same. Tens: 8 is more than 2. So 4 382 is greater than 4 328.

Worked example

Which is higher: El Tucuche (936 metres) or El Cerro del Aripo (940 metres)?

Show me how

Both numbers have three digits.

Hundreds: 9 and 9 are the same.

Tens: 3 and 4. 4 is more than 3.

So 940 is greater than 936. El Cerro del Aripo is higher, by 4 metres.

The greater than and less than signs

We use signs to compare numbers. means is greater than. means is less than. = means is equal to.

5 607 5 076

2 199 2 910

A good trick: the open side of the sign always faces the greater number. The point faces the smaller number.

Watch out! A common mistake

Do not look only at the first digit you see. 989 1 200, even though 9 is more than 1. The number 1 200 has more digits, so it is greater.

Putting numbers in order

Ascending order means from smallest to greatest. Descending order means from greatest to smallest.

Worked example

Put these numbers in ascending order: 3 450, 3 045, 3 504, 3 405

Show me how

All the thousands digits are 3.

Compare the hundreds: 4, 0, 5, 4. The smallest is 3 045 and the greatest is 3 504.

For 3 450 and 3 405, compare the tens: 0 is less than 5, so 3 405 comes first.

Answer: 3 045, 3 405, 3 450, 3 504.

Largest and smallest from four digits

With the digit cards 5, 0, 8 and 3 you can make many numbers. To make the largest, put the biggest digit in the thousands place, then the next biggest, and so on: 8 530.

To make the smallest, start with the smallest digit, but a four-digit number cannot start with 0. So start with 3, then put the 0: 3 058.

Watch out! A common mistake

0 358 is not a four-digit number. It is just 358. Never put 0 in the thousands place.

Recap

  • A number with more digits is greater.
  • If two numbers have the same number of digits, compare from the left until the digits are different.
  • means is greater than and means is less than. The open side faces the greater number.
  • Ascending order is smallest to greatest. Descending order is greatest to smallest.
  • To make the largest number, put the digits from biggest to smallest. A four-digit number cannot start with 0.

Words to know

greater than
More than. Its sign is .
Example: 5 000 4 999 means 5 000 is greater than 4 999.
less than
Fewer or smaller than. Its sign is .
Example: 2 199 2 910 means 2 199 is less than 2 910.
ascending order
Arranged from smallest to greatest.
Example: 1 008, 1 080, 1 800 is in ascending order.
descending order
Arranged from greatest to smallest.
Example: 9 110, 9 100, 9 010 is in descending order.
compare
To look at two things to see which is greater or smaller.
Example: We compared the heights of two mountains.

Try it at home

  • Look at the prices of three items in a shop flyer or on receipts. Put the prices in order from cheapest to dearest.
  • Mini project: find out how many pupils are in three schools near you (ask an adult or a teacher). Write the numbers in descending order and use signs between them.

Test tips

Tips for class tests

  • Line the numbers up by place value, one under the other, before comparing.
  • After writing a sign, read the whole sentence aloud, for example “4 805 is less than 4 850”, to check it makes sense.
  • Read the question carefully: ascending and descending are opposites.

For parents and teachers

After this lesson, your child should be able to:

  • compare numbers up to 10 000 using place value;
  • use the greater than and less than signs correctly;
  • order numbers in ascending and descending order, and make the largest and smallest numbers from four digits.

A common error is comparing only the first digits, or forgetting that 10 000 has five digits. Ask your child to explain which place decided the answer.

Place Value and Expanded Notation – Standard 3 Maths

What you will learn

  • Say the value of each digit in a number up to 9 999.
  • Write a number in expanded notation, and change expanded notation back into a numeral.
  • Describe the same number in different ways, such as 624 tens and 5 ones.

Every digit in a number has a job. In 7 777 all four digits are 7, but each 7 is worth a different amount. In this lesson you will find out why. You will learn to break numbers into parts and put them back together.

Place and value

The place of a digit is where it sits in the number. The value of a digit is how much it is worth in that place.

ThousandsHundredsTensOnes
7777
7 000700707

In 7 777 the first 7 is worth 7 000. The next is worth 700, then 70, then 7. Each place is worth ten times the place to its right.

Worked example

What is the value of the digit 4 in 2 456?

Show me how

Find the place of the 4. Count from the right: ones, tens, hundreds.

The 4 is in the hundreds place.

4 hundreds = 400.

Answer: the value of the 4 is 400.

Expanded notation

Expanded notation shows a number as the sum of the values of its digits.

4 352 = 4 000 + 300 + 50 + 2

When a digit is zero, it is worth nothing, so we can leave it out: 5 060 = 5 000 + 60.

To go back to a numeral, put each part in its place. The parts can be in any order: 7 + 2 000 + 400 = 2 407.

Worked example

Write 3 000 + 40 + 5 as a numeral.

Show me how

3 000 means 3 thousands.

There is no hundreds part, so the hundreds digit is 0.

40 means 4 tens and 5 means 5 ones.

Answer: 3 045.

Watch out! A common mistake

Do not just join the digits together. 3 000 + 40 + 5 is not 345. Check each place: thousands 3, hundreds 0, tens 4, ones 5. The answer is 3 045.

One number, many ways

You can describe a number in more than one way. Look at 6 245:

6 thousands, 2 hundreds, 4 tens and 5 ones
62 hundreds and 45 ones
624 tens and 5 ones
6 245 ones

They all mean the same number! 62 hundreds is 6 thousands and 2 hundreds put together. 624 tens is all the tens in 6 245.

Worked example

How many tens are in 3 580?

Show me how

Cover the ones digit: 358 | 0.

The digits left over tell you the number of tens.

Answer: 358 tens. 358 tens = 3 580.

Recap

  • The value of a digit depends on its place: thousands, hundreds, tens or ones.
  • Expanded notation adds the values of the digits: 4 352 = 4 000 + 300 + 50 + 2.
  • Zeros are left out of expanded notation, but they must be written in the numeral.
  • One number can be described in many ways: 6 245 is 62 hundreds and 45 ones, or 624 tens and 5 ones.

Words to know

place value
The value a digit has because of its place in a number.
Example: In 2 456 the place value of 4 is hundreds.
value
How much a digit is worth.
Example: The value of the 4 in 2 456 is 400.
expanded notation
A way of writing a number as the sum of the values of its digits.
Example: 5 060 in expanded notation is 5 000 + 60.
base ten blocks
Blocks that show ones, tens, hundreds and thousands.
Example: We used base ten blocks to build 1 245.

Try it at home

  • Make digit cards from paper (0 to 9). Pick four cards, make a number and write it in expanded notation.
  • Mini project: make a place value chart on a sheet of paper with four columns. Use beans or buttons as counters to show three different numbers, and ask an adult to read them.

Test tips

Tips for class tests

  • Label the places above the digits (Th, H, T, O) before you answer.
  • In expanded notation, check that each part has the right number of zeros.
  • When changing expanded notation to a numeral, put a zero in any empty place.

For parents and teachers

After this lesson, your child should be able to:

  • give the value of any digit in a four-digit number;
  • write numbers in expanded notation and back again;
  • describe a number in different ways, such as 62 hundreds and 45 ones.

Watch for children who join digits (writing 3 000 + 40 + 5 as 345). Ask them to say the value of each part aloud. A place value chart drawn on paper helps a lot.

Numbers to 10 000: Count, Read and Write – Standard 3 Maths

What you will learn

  • Count on and count back with numbers up to 10 000, by ones, tens, hundreds and thousands.
  • Read four-digit numbers and write them in numerals and in words.
  • Find the missing numbers in a counting sequence.

In Standard 2 you worked with numbers up to 1 000. Now the numbers get bigger! In this lesson you will count all the way to 10 000. That is about the number of people who can sit in a big cricket ground. You will learn to say, read and write these big numbers, and you will build them with base ten blocks.

Counting past 1 000

Counting with big numbers works just like counting with small numbers. When you count on by ones, the ones digit goes up each time. When the ones reach 9, the next number makes a new ten.

Watch what happens when we count on from 997:

997, 998, 999, 1 000, 1 001, 1 002

After 999 comes 1 000 (one thousand). The same thing happens at every thousand: 2 999 is followed by 3 000, and 9 999 is followed by 10 000 (ten thousand).

To count back, you go down by one each time: 4 002, 4 001, 4 000, 3 999, 3 998.

We write a space after the thousands digit, like this: 4 521. The space helps you read the number. It is still one number!

Skip counting by 10, 100 and 1 000

Skip counting is a quick way to count. You jump the same amount each time.

Count on in tens and only the tens digit changes, until it passes 9: 2 470, 2 480, 2 490, 2 500.

Count on in hundreds and the hundreds digit changes: 1 600, 1 700, 1 800, 1 900, 2 000.

Count on in thousands and the thousands digit changes. Look at this pattern: 1 340, 2 340, 3 340, 4 340. The other digits stay the same.

Worked example

Count on in hundreds from 1 650. Write the next four numbers.

Show me how

Only the hundreds digit changes. It goes up by 1 each time.

1 650, 1 750, 1 850, 1 950.

The next jump passes nine hundreds. 1 950 + 100 = 2 050, so the thousands digit goes up to 2.

Answer: 1 750, 1 850, 1 950, 2 050.

Reading and writing big numbers

To read a four-digit number, read the thousands first, then the hundreds, then the last two digits. A place value chart helps.

ThHTO
4521

4 521 is read as four thousand, five hundred and twenty-one.

When a number has a zero, we do not say that part. 3 005 is three thousand and five. There are no hundreds and no tens, but the zeros must still be written. They hold the places.

Worked example

Write six thousand and forty in numerals.

Show me how

Six thousand: the thousands digit is 6.

There are no hundreds, so the hundreds digit is 0.

Forty is 4 tens and 0 ones.

Answer: 6 040.

Watch out! A common mistake

Some children write three thousand and five as 30005 or 305. Both are wrong. A number in the thousands has four digits. Put a zero in each empty place: 3 005.

Counting with base ten blocks

Base ten blocks help you see big numbers. Ten ones make a ten (a rod). Ten tens make a hundred (a flat). Ten hundreds make a thousand (a big cube).

If you have 2 thousand cubes, 3 hundred flats, 1 ten rod and 6 ones, the number is 2 316.

To find a missing number in a sequence, first find the jump. In 5 200, 5 300, ____, 5 500 the numbers go up by 100 each time, so the missing number is 5 400.

Recap

  • When you count on past 999, 1 999, 2 999 and so on, you reach a new thousand.
  • Skip counting by 10, 100 or 1 000 changes the tens, hundreds or thousands digit.
  • Read big numbers from the thousands down: 4 521 is four thousand, five hundred and twenty-one.
  • Zeros hold empty places: three thousand and five is 3 005.
  • To find a missing number, work out the jump first.

Words to know

thousand
Ten hundreds. It is written 1 000.
Example: There are about one thousand pages in that big dictionary.
numeral
A number written with digits, like 2 316.
Example: The numeral for two thousand is 2 000.
digit
One of the symbols 0 to 9 that we use to write numbers.
Example: The number 7 068 has four digits.
sequence
Numbers in an order that follows a rule.
Example: 2 470, 2 480, 2 490 is a sequence that goes up by ten.
skip count
To count by jumping the same amount each time.
Example: We can skip count by hundreds: 300, 400, 500.

Try it at home

  • Find big numbers at home or outside: on a calendar (the year 2026), a car number plate, a receipt or a sign. Read each one aloud to an adult.
  • Mini project: make a counting strip. Start at 1 900 and count on in tens to 2 100. Write each number on a strip of paper and hang it on the wall.
  • Play “What comes next?” One person says a number and a jump, like “3 400, jump 100”. The other says the next three numbers.

Test tips

Tips for class tests

  • Always check how many digits your answer has. Numbers from 1 000 to 9 999 have four digits.
  • When writing a number from words, write a zero for any place that is not mentioned.
  • In a missing-number question, check the jump between two numbers you know before you fill the gap.

For parents and teachers

After this lesson, your child should be able to:

  • count on and back by ones, tens, hundreds and thousands up to 10 000, including across a thousand (for example 2 998, 2 999, 3 000);
  • read and write numbers to 10 000 in numerals and in words;
  • find missing numbers in a counting sequence.

Ask your child to read numbers seen every day, such as prices and the year. Most mistakes happen when crossing a thousand (999 to 1 000, 4 999 to 5 000), so practise counting on and back around those numbers.
