Add and Subtract 5 -8 digit numbers: Formal Method

This is a large set of differentiated Worksheets providing an (almost) endless source of practicing column addition and subtraction of numbers from 5-Digit to 8-Digit using the formal written method.

The first set of worksheets, adding & subtracting a 4-digit number from a 5-digit number, can serve as a useful interim step between adding & subtracting 4-digit numbers and adding & subtracting 5-digit numbers. It helps bridge the gap between these two levels of difficulty and provides a valuable transition in the learning process.

The Worksheet Sets are as follows

Add a 4- and 5-Digit number & subtract a 4-Digit from a 5-Digit number
Add & subtract two 5-Digit numbers
Add three 5-Digit numbers
Add four 5-Digit numbers

Add & subtract two 6-Digit numbers
Add three 6-Digit numbers
Add four 6-Digit numbers

Add & subtract two 7-Digit numbers
Add three 7-Digit numbers
Add four 7-Digit numbers
Add mix (3) of 5-, 6- 7- Digit numbers

Add & subtract two 8-Digit numbers
Add three 8-Digit numbers
Add four 8-Digit numbers
Add mix (3) of 6- 7- 8- Digit numbers

There are 15 sets of addition and 5 sets of subtraction that build up from smaller to larger numbers and with addition going from adding together 2 numbers up to 4 numbers, it will enable you to set the level of practice that is right for your students to build accuracy, speed and confidence over whatever time frame is necessary.

Layout of Questions
For all of the above, the questions are presented in 2 layouts:
• The standard algorithm, laid out vertically with the questions and answer lines prepared.

• The questions are presented in the horizontal format so that your students have to properly align the digits based on their place values, which is essential for accurate addition & subtraction. This practice reinforces the concept of place value and helps students develop a better understanding of how digits in different positions represent different values.
** This format could also be useful for practicing addition with any informal methods that are part of your syllabus or even estimation **

Number Formats
For these resources you have a choice of 3 different number formats which will cover most educators’ needs around the world. Your students will come across at least 2 of the formats within their time at school in other curriculum areas

• A comma separator - for the USA & UK e.g. 23,334,290
• A space separator - Canada, Australia, many European countries, and the International System of Units (SI) e.g. 23 334 290
• No separator - used in scientific writings, page numbers, years & addresses etc. e.g. 23334290

How many Worksheets in each set?
Almost unlimited. At the click of a button all numbers are randomized, and will therefore change every time so you can create as many different worksheets for classwork, homework, revision, preparing for assessment, review before moving on to 5 or more -digits, etc.
