These PowerPoints are designed to aid the teaching of doubling and halving. They show a method (partitioning) that will be helpful when doubling or halving any number. They focus on two digit numbers (including decimals involving tenths) and three digit numbers. The tricky subject of halving three digit numbers with odd numbers of tens is covered with the suggestion of a ‘trick’ to overcome the difficulty. In each case, there are a number of examples with which to practise the method - ideal for whole-class whiteboard exercises. The examples increase in difficulty where possible. I hope you find these useful. If you do, please post a review so that others know they are worth downloading.

The PowerPoints are designed to help introduce or revise the technique of adding and subtracting numbers with decimal places, using money (£ and p) as the main context. They each include an instructional section followed by a number of examples. The level of difficulty gradually increases. There are further examples towards the end, showing that the same technique works for numbers and measures. The ‘golden rule’ of aligning the decimal points is stressed and illustrated. In addition, there are four worksheets for each operation: Number 1 is the simplest and includes a detailed ‘instructional’ preamble; Number 2 has a less detailed preamble followed by the same questions as number 1 plus another 10; Number 3 increases the skill level - to adding three numbers for addition and to working with 2 decimal places for subtraction - and includes questions in the context of pounds and pence; Number 4 deals with numbers that have different numbers of decimal places. There is an answer sheet for each set. I hope you find this resource useful. If you do, please give it a positive review so that others know that it’s worth downloading. Thanks!

These PowerPoints will help teachers introduce or revise the technique of adding and subtracting by compensation (e.g. add ten, subtract one to achieve add nine). They use visual representations to demonstrate the effects and each provides a number of practice examples using two digits and then three digits. They finish with the challenge to work out how to add/subtract 19, 29, 49 and 99. I hope you find this resource useful. If you do, please leave a review to that effect so that others know that it’s worth downloading.

This PowerPoint is designed to help with the teaching or revision of a mental method for adding decimal numbers by equating the process with a mental method for the addition of integers. The PPT provides some teaching slides and lots of examples. They develop from working with numbers with tenths only to tackling those with tenths and hundredths. The early examples do not bridge the columns but the later ones do. I hope you find this resource useful. If you do, please give it a positive review so that others know that it’s worth downloading. Thanks!

This is a PowerPoint to help consolidate skills with adding (counting on) one, ten or a hundred from a given number. It includes demonstration slides and five on-screen examples. There is a short extension on the end that looks at the effect of having a 9 in the relevant column and how that might be dealt with. I hope you find this resource helpful. If you do, please leave a review to indicate to others that it is worth downloading. Thank you.

These resources will help you to teach some aspects of the sometimes tricky subject of algebra and provide valuable practice. The emphasis is on ‘demystifying’ algebra, presenting the tasks clearly and simply and stressing how easy the work is. There are four PowerPoints: An introduction to algebra, explaining what it is and guiding pupils through solving simple equations with missing numbers; Two that explain and practise equations (the second being more challenging than the first); An explanation of algebraic expressions, with examples to aid understanding and provide practice. In addition, there is a batch of worksheets on equations, in both editable MSWord format and as PDF for direct printing. I hope you find these resources useful. If you do, please post a review so that others know that they are worth downloading.

These PowerPoints are designed to help with the teaching of or revision of bonds. They presume an existing knowledge of bonds to 10. One is a PowerPoint to help to introduce or revise the technique of using knowledge of bonds to speed up addition of several numbers (a number ‘string’). The slides are animated to help with seeing the process. The examples are all single digits. Another shows how knowledge of bonds to ten facilitates bonds to 100 using multiples of ten. Another shows how to bond any two-digit number to 100 using the idea of ‘make ninety-ten’. Another shows how to find bonds to ten involving decimal numbers, equating the process to the ‘ninety-ten’ idea. Finally, I’ve added a PowerPoint that simply practises bonds to 20. It has no teaching slides. I hope you find these resources useful. If you do, please give them a review, to indicate to others that they are worth downloading.

These resources are to aid the teaching and practice of a variety of mental methods for multiplications. The PPTs cover: multiplying by 4; multiplying by 5 and 50; multiplying by 15; multiplying by 11; multiplying by 25; using the associative law to aid multiplication. The worksheets cover: multiplying by 2, 4, 8 and 16; multiplying by 5, 10 and 15; multiplying by 11; using the associative law; multiplying by multiples of ten. The worksheets are in MSWord and PDF formats and answers are included. In each case, one suggested method is shown. There are, obviously, other methods that could be used. I hope you find this resource useful. If you do, please leave a review so that others know that it is worth downloading.

These worksheets are designed to keep essential maths skills ‘on the boil’. Each sheet includes a section on addition, subtraction, multiplication and division. These operations include all the skills that Year 6 should already have or be mastering, such as long multiplication and working with decimal numbers. In addition, there are sections on fractions, percentages, squares, cubes, primes, factors, multiples and algebra spread amongst them. I used them as weekly homeworks, ensuring that whatever we were doing in the classroom, the children were being forced to keep on top of these essential operations and skills. They are all saved both as Word documents (for editing, if desired) and as PDFs, for direct use. The answers are also saved as Word documents and PDFs in the same format as the question sheets, for easy checking. I hope you find them useful! If you do, please leave positive feedback as an indication to others that this resource is worth downloading.

This is a collection of PowerPoints that teach, revise and/or practise subtraction by counting on, compensation or the ‘vertical’ method. Some use whole number examples while others use decimals. Some of the PowerPoints have teaching slides and advice within them while others assume the method has already been taught and simply provide an opprtunity to revise it. I hope the names make it clear which are which. There is a degree of cross-over or repetition between the different PowerPoints about counting on, but that could be helpful where revision or consolidation is required. Subtraction by counting on can be particularly useful when crossing number boundaries, often removing the need to borrow across several columns that the formal written method may require (e.g. 1006 - 997). These are all original to me, not borrowed from elsewhere. I hope you find at least one of these files useful. If you do, please post an appropriate review so that others can see the benefit of them.
