One of the easiest ways of subtracting nine from a number is to subtract ten and then add one. This is a simple mental arithmetic ‘trick’ which many children do not pick up on and is much quicker than counting back nine using fingers etc. Probably the only time this method is not the most […]

Children should be very familiar with counting up and down in fives before attempting these worksheets. All the numbers on the pages are multiples of 5. Join them in pairs so that each pair adds up to 100. Watch out for a common error with this type of work whereby children add an extra 10 […]

# Resource of the Week: Maths Worksheets on Change from 10p

10p will buy you a sweet. But how much change will you get? I am sure that your child enjoys playing ‘shop’ at home and these four worksheets provide extra re-inforcement for them at giving change from 10p. These days you tend to get your change plonked into your hand with the till receipt – […]

# What’s New: Add a 2-digit number to a multiple of 10

The next in our rapidly developing series of addition worksheets for children who are getting more confident with mental arithmetic and can handle 2-digit numbers. These pages look at adding a 2-digit number to a multiple of 10, again all answers keep to below 100. This is also good reinforcement of place value. Watch out […]

# What’s New: Adding without crossing the tens boundary

Here we have a set of worksheets which looks at addition of two 2-digit numbers, but they have been organised so that the tens boundary is not crossed. In other words, the total of the units is always less than ten. This is a good exercise as it highlights the possibility of carrying out a […]

This is a favourite with me as it is such an easy little trick to remember, which also makes addition easier. When I was thinking about how I do calculations in my head I realised that if I had to add nine I usually took two steps. Firstly, I added ten and secondly, I took […]

# What’s New: Multiplication and shopping

Karen, from North London has asked us if we have any further ideas to help with multiplication. Setting up a little shop and buying and selling things has always been a great part of early maths, but usually this activity is limited to adding up and giving change. It can be used equally well to […]

# Superbrains! Subtracting whole tens

Here we have a set of worksheets which looks at subtraction of whole tens. Once children have become confident with counting forwards and backwards in ones and twos the next step is to be able to count in tens. Be careful, however, as some children can rote learn this with no understanding of how large […]

# What’s new: Estimating on a number line

This week we are publishing a quite tricky set of maths worksheets in the Superbrain section, all about estimating on a number line. The number line is from 0 to 10, but there are no numbers shown between these, and children have to estimate where numbers would lie. It is not expected that they will […]

# What’s New: Complete addition number sentences

We have had several requests for more pages on addition for children who have gained confidence with adding single digits and want to move on, so for the next week or so we are going to include as much as we can on this area. This set of four worksheets looks at completing number sentences. […]
