With the question above, the suggestion is to find the nearest multiple of 10 and adjust. Subtracting 30 from 55 is far easier than subtracting 29. This method relies on pupils understanding that subtracting 30 and adding 1 is the same as subtracting 29.

Liability 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. Missing Number Problems Worksheets Missing Number Addition, Missing Number Subtraction, Missing Number Multiplication, Missing Number Division 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.

Until pupils are confident with a range of different methods and explaining their method, it is often useful to provide them with a range of concrete and pictorial representations. Eventually, these can be removed and pupils can work with the abstract concepts alone, as is exemplified with the second question. Pupils should be able to use the information gained in the first question to help them solve the second question. ii.

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.

A question involving multiplying three numbers may look intimidating at first, however, when pupils use their known number facts, they become far easier to solve. Adding decimals mentally can be difficult. This is the type of question where estimating, using whole numbers and jottings can be helpful. By estimating the answer first, pupils will get a good idea of what their answer should be. If, when finding the exact answer, the two are vastly different, pupils will know they have made a mistake. This does rely on pupils understanding how to estimate accurately.

If when adding 9 to a number, for example, the pupil counts in ones instead of adding 10 and adjusting, they are using an inefficient and slow method.

When completing these calculations mentally, encourage pupils to avoid thinking they are adding or subtracting zeros as this will embed misconceptions.

However, it is important that pupils understand that completing calculations mentally is not always the best strategy. They need to become adept at analysing a calculation to decide if it is best to complete it using a mental or a written strategy. Pupils should learn number bonds within 20 in Year 1. This should then become part of their rapid recall and enable them to complete related calculations easily in subsequent years. Teachers or parents can initially work through the worksheets with the children in their care to ensure they have a good understanding of the technique(s) to be practised. Children can then finish the worksheet and complete further worksheets independently. Share your account login details with anyone else or place the details on the internet. Users of Audio Files This gets sent home for homework once a week. It's seen by the children as a test? Which it is. Swapping through addition,subtraction,fractions, giving change, and all sorts in the same homework sitting is not consolidation of what's been taught that week in class. As parents we don't know what's been taught that week or the week before, or the approaches used,methodologies taught..nothing. We have no text book to consult with the work programme in it either. Testing children repeatedly, sometimes on topics they haven't even covered yet leaves the children deflated and makes homework frustrating. Are the books meant to be used this way?
