There are a number of alternative methods used to solve these problems (and especially with 2 & 3 digit numbers), but the standard algorithm at this level is probably the best preparation your pupils can have for working with decimal numbers which will follow in Grade 5.Â Â These sets of worksheets focus on addition and subtraction working primarily with 4 and 5 digit numbers. Â Â Â Â

On each Worksheet there are three buttons, each of which will randomise the numbers in the questions at 3 levels, namely addition and subtraction with:

-4 digit numbers only

• -5 digit numbers only

• -A mix of 3,4 or 5 digit numbersÂ

The questions are presented in the standard column format so students can start working on them straight away.

How many worksheets are in each set ?

Lots and lots. At the click of a button all numbers are randomised, so the questions change every time.Â  This will allow you to create as many new worksheets you will need for practice throughout the year or even give groups of pupils in your class different sets of questions.

There will certainly be enough to ensure fluency in this topic.Â

Answers can be found on the second page of every worksheet, automatically generated when you create a new worksheet.

You can also remove all numbers from the sheet, so you have a blank template to work with or for your pupils to create their own set of questions.

Note
These resources are PDF documents and work with the officialÂ  Adobe Acrobat Reader on Windows or Mac computers with the randomising buttons also working via a touchscreen or on an Interactive Whiteboard.
