About this resource

Round multi-digit whole numbers to the nearest 10, 100, 1000, 10,000 or 100,000 using place value with unlimited Worksheets plus resources for the Interactive Whiteboard (or PC or Mac)

There are two sets of worksheets:

1. Using Place Value on the Number Line to round to the nearest 10, 100 or 1000

Every worksheet has 4 number lines containing 16 questions
The top Number Line has 10 divisions between every multiple of 10, 100 or 1000 . This reduces until the last Number Line, so that students must think more about the values of the scales and the rounding process.

2. Round using Place Value to the nearest 10, 100, 1000, 10,000 & 100,000

There is a Worksheet set for each level plus one with a mix of all levels with an example shown.

Number Formats

You have 3 choices:

  • Comma separator: e.g. 23,334,290

  • Space separator: e.g. 23 334 290

  • No separator: e.g. 23334290

How many Worksheets in each Set ?
Virtually unlimited. Numbers change at the click of a button.  You can print as many worksheets at each level as needed for practice throughout the year or even give small groups of students in your class different sets of questions either at the same level or differentiated. There will certainly be enough to ensure fluency in this topic.

Answers are automatically generated when you print out a new worksheet.
Lastly, it's essential to note that these resources are compatible PDF documents. They operate with the official Adobe Acrobat Reader on both Windows and Mac computers. Plus, the randomising features are effortlessly accessible via touchscreen devices or interactive whiteboards.

Teaching tips & learning objectives

Learning objectives

  • Round multi-digit whole numbers to a given place from tens to hundred thousands

  • Locate a number between two multiples on a number line to decide which it rounds to

Teaching tips

  • The teaching-page files need an interactive whiteboard, touchscreen or computer; they could be used to model the number-line method before students start the printed worksheets.

Skills covered

  • Rounding with a number line — placing numbers between marked multiples and choosing the nearer one

  • Place value reasoning — rounding as number-line labels become less detailed
