Year 4 Maths Properties of Numbers Number have lots of different properties (characteristics). It's a good idea to learn about them, as you'll use them a lot at school. We've broken down the main properties of numbers over the next couple of pages, so have a go at completing the exercises to make sure you've got them sorted! Factors A factor is a number that divides exactly into another number (e.g. a factor of 12 is 4, because 12 can be divided by four exactly). Some numbers have lots of factors, whereas others don't have many at all. If you're asked to list all of the factors of a number, it's best to do so in their pairs. This will help you to make sure that you've not missed any out! These are the numbers that multiply together to make 12 List all the factors of 12: ( 1, 12 ) ( 2, 6 ) ( 3, 4 ) Every number has at least 2 factors (1 and itself) Now have a go at listing all of the factors of the numbers below: 24 50 48 32 100 180 Multiples Multiples are super easy! They are simply the answers to the times tables of a given number. Every number has a never-ending amount of multiples, so you'll never be asked to list all of them. You'll usually just be asked to list the first few. List the first 5 multiples of 7: 7, 14, 21, 28, 35 Now have a go at listing the first 5 multiples of the following numbers: 4 6 12 25 8 200
Year 4 Maths Properties of Numbers Continued Prime Numbers Prime numbers are awkward numbers! They can only be divided by themselves and 1. Because of this, you won't tend to find them in any of the times tables. The number 2 is the only even prime number. All other prime numbers are odd. There are no other even prime numbers, because all even numbers can be divided by 2! Similarly, you know that if a number ends in 5 or 0 (except for the number 5 on its own) it can't be prime. This is because all numbers that end in 5 or 0 can be divided by 5 or 10. The number 13 is a prime number because it can only be divided by itself (13) and 1. It cannot be divided equally by any other number. Circle all of the prime numbers in the box below: 4 19 2 35 27 18 63 15 7 59 91 Square Numbers Square numbers are the answers you get when you multiply a number by itself. For instance, the number 16 is a square number, because 4 x 4 = 16. Sometimes you'll see this written as 4² = 16. The little '2' means 'squared'. What is 9²? 9² = 81, because 9 x 9 = 81 Answer the sums below to find the square numbers: 8² = 6 x 6 = 12 x 12 = 7² = 11² = 5 x 5 =
Year 4 English Adjectives Adjectives are used to describe a noun (an object or thing) Adjectives help to make our writing more interesting by adding extra detail. For example: beautiful, excited, terrible are all adjectives Quick Activity 1 See if you can spot and underline the adjectives in each of the sentences below.
