# Interactive rounding resources

Introduce the topic using the Smart Notebook activity.

8 identical pages, each with a blank number line, a movable arrow to show the position of the number to be rounded and a sentence at the bottom to state what is happening.

Learners can fill in the ends of the number line to see what values are relevant to the question i.e. rounding 23 to the nearest 10 would be either 20 or 30 as an answer. Then they can move the arrow to the position needed, 23, then see which value the number is closest to.

Hence the value and what you are rounding to can be differentiated across ability ranges.

Please note you must have the Smart notebook software installed on your computer in order to open, view and use this resource http://smarttech.com/

Then learners can use the self checking Excel sheet to consolidate their learning (or this could be displayed on an IWB for group work). Three sheets for rounding the the nearest 10, 100 and 1000 and then the final sheet can be programmed by the student.
