Mental arithmetic for Years 4, 5 and 6

The final sets of mental arithmetic for this term have now been published, with two more sets for each of years 4, 5 and 6. Year 4 looks at doubling, multiplication and shapes. Doubling twice can be an effective way of multiplying larger numbers by 4 ‘in your head’. There are also several questions which […]

Multiply by 4 by doubling twice

Here is a set of worksheets, suitable for year 4 children, which looks at multiplication by 4 using mental methods. With 2 and 3-digit numbers often the easiest way to do this is to double the number and then double again. This is just one of the many strategies that children should use when working […]

Mental arithmetic for Years 4, 5 and 6

The most recent sets of mental arithmetic questions have now been published for years 4, 5 and 6. For year 4 it is very much about multiplication and division, including some of the easier rules of divisibility eg a number is divisible by five if the units are five or zero. The year 5 sets […]

Multiplying by 10 and 100

We have just published another set of maths worksheets on multiplying 2-digit and 3-digit numbers by ten or one hundred. Multiplying by ten moves each digit one place to the left, whilst multiplying by one hundred moves each digit two places to the left. Zeros are placed in the empty spaces, but don’t fall into […]

Year 4 maths worksheets: More products

Year 4 maths worksheets: multiples and products

It’s a very fishy time as we look at multiples and products, suitable for year 4 upwards, for children who are gaining a good knowledge of times tables. To know whether a number is a multiple of 3 for example, it is very useful to know the rules of divisibility, as this avoids having to […]

Consecutive numbers in a 3 by 3 square

This is really a mini version of investigating a 100 number square, but many children will feel more confident when faced with a less daunting starting point. Choose any nine consecutive numbers and place them in order (from left to right) in a 3 x 3 square. Add the diagonals. What do you notice? A […]

5 Digit Addition Investigation

This is a great little investigation which has plenty of extension possibilities for those with enquiring minds. Dom the Dragon is thinking of a number and we are given two rules about the number: 1. The digits add up to 5. 2. None of the digits is a zero. The challenge is to find all […]

Year 4 maths: Tenths of rectangles

Two of the best ways for children to understand decimals are: a. by using money b. by looking at shapes which are divided into tenths. This set of pages looks in more detail at shapes. A series of rectangles is shown, each divided into ten equal parts: each part being one tenth. This is a […]
