## Maths puzzle: One to nine (2)

Our first ‘One to Nine’ puzzle proved to be very popular so here is another. Aimed at upper juniors, (9-11 yr old) there are a few points to consider when getting started with these puzzles. Firstly, the rules of Bodmas do not apply; the sentence is calculated in the order shown. Secondly, each digit can […]

## Year 6 maths worksheet: Estimating on a number line

This is the follow up maths worksheet to the earlier explanation on how to estimate on a number line up to 10 000. Most of the work on number lines in year 6 involve using decimals so this is a good chance to make sure that large whole numbers are understood. All answers are approximate […]

## Coming soon: more estimating, number puzzle and calculator activities

## Maths worksheet: Divide decimals by 10 or 100

This is the second in our revision sheets for dividing decimals by 10 or 100, ‘in your head’. A good understanding of place value is needed for this as there is little to do apart from move the numbers to the right. One place to the right divides by 10. Two places to the right […]

## Resource of the Week: Year 2 maths worksheet

This is the second page which looks in detail at a 1-100 number square and is excellent practice at understanding place value as well as counting.

## Year 3 maths worksheet: Make 5 sided shapes

Usually these shapes are seen in a regular form and children do not always recognise them when they are irregular. This mini investigation will help with this. A geoboard is a great help. Schools already have […]

## How to estimate on a 0-10 000 number line

This is a much trickier exercise than it first appears. Firstly, children need to be confident with reading large numbers and counting in thousands. Secondly they need to be able to visualise marks on a scale. Only the zero and 10 000 are marked on the number line so it would be a good idea […]

## Coming soon: Estimating, 5 sided shapes and dividing decimals

Firstly, children need to be confident with reading large numbers and counting in thousands. Secondly they need to be able to visualise marks on a scale. By Year 3 children should be […]

## Year 5 Calculator game: Multiples of 7

This is the next in our series of calculator activities and is certainly one of the hardest. It looks at multiples of 7, including numbers above 10 and will test children’s knowledge of the 7 times table to the full. Again, the idea is to play with a partner and cover 4 squares in a […]

## Resource of the Week: Year 5 fractions and division

The relationship between fractions and division is one which many children fail to grasp. Put simply, one fifth of 30 is equivalent to 30 divided by 5, or written as a fraction 30 over 5. It can be a great help to see a fraction as a division calculation. 1/2 can also be thought of […]
