When introducing mental methods, we recommend drawing the pupils’ attention to the most efficient method they could use for a question, and then explaining why in that case, it is the best choice.

Users of Audio Files When multiplying by a multiple of 10, pupils can partition the multiple of ten to make the calculation easier to solve. In this example, the pupil could partition 40 into 10 x 4. This makes the calculation far easier to solve as they can multiply 4 by 5, then multiply the product by 10.

Termination Rote learning is often frowned upon in modern education - understandably in most subjects - however with elementary mathematics some rote learning is essential. If pupils know 3 + 7 = 10, they should recognise that 70 and 30 are ten times larger than 3 and 7, therefore the answer should be 10 times larger than 10. will always equal 7, 4x5 will always equal 20, and so some rote learning (learning by repetition and/or memorisation - in this case with worksheets) is a suitable and efficient way to practise and develop mathematical skills and techniques so that they become second nature; hard-wired number facts in a young person’s brain. You don’t have to think when asked what is 2+2: you just know that it is 4. The sooner that a child just knows certain number facts, the better, but that knowledge comes only through practice.

This method involves starting from 29 and counting on in ones and tens until you reach 55. Some pupils may struggle with this method as they may not understand the meaning of ‘difference’ and the ways of finding the difference. They may also not understand the relationship between addition and subtraction. Of all the mathematics taught in schools, it is that taught to children before the age of 11 which is most important in the rest of their lives. Most people will never use anything they learn in mathematics lessons after that age in their adult life, but good basic number skills and mental arithmetic ability will remain a powerful tool to have and use every day.

Multiplying and dividing by 10 and 100 can cause some confusion with pupils. When completing these calculations mentally, encourage pupils to avoid thinking they are adding or subtracting zeros as this will embed misconceptions.

When completing 2 x 4 x 5, pupils could identify that 2 x 5 = 10 and multiply this by 4 or complete 4 x 5 and multiply the product by 2. By identifying easier calculations to multiply, they can find more manageable numbers to work with. There are times where pupils may struggle with this. For example, with the second question, if pupils first complete 9 x 2 = 18, they may then struggle to answer 5 x 18. BIDMAS questions

When multiplying by 10 mentally, there are several methods pupils could use. When multiplying a one-digit number by 10, they may be able to recall the answer (e.g. 8 x 10). They could also count in tens, although this method could be inaccurate. Pupils could also imagine a place value grid and mentally move the digits one column to the left. This method would also work for multiplying two-digit numbers by 10. Mental Arithmeticprovides rich and varied practice to develop pupils’ essential maths skills and prepare them for all aspects of the Key Stage 2 national tests. It may also be used as preparation for the 11+, and with older students for consolidation and recovery.

To solve the division calculations, pupils may find it easier to complete the inverse, for example 72 ÷ 9 is the same as 9 x ? = 72. They can then use a multiplication method to find the answer. Mental maths questions: multiplying and dividing by 10 (and multiples of 10) Year 2 children are expected to add three one-digit numbers. With question d, pupils should look for number bonds first. If they can see that 7 + 3 = 10, solving the rest of the calculation becomes much easier. When solving this calculation, it is essential that pupils understand that addition is commutative. Mental maths questions: addition and subtraction example The methods pupils will have developed when multiplying by 10 can be applied to multiplying by 100. Another method that can be used is multiplying the multiplier by 10 then multiplying the product by 10. This would rely on the pupil understanding that x 10 x 10 is the same as x 100.
