This activity will help you practice rounding numbers from 10 to 100,000. The activity progresses in levels. The level is tied to what "decade" the number should be rounded. Level 1 is rounding to 10, Level 2 is rounding to 100 and so on. There are 5 levels in the activity.

There are three sections inside each level. The sections give the player different ways to enter the answer.
-Section 1 is a slider. Move the slider to the correct answer and click OK.
-Section 2 is 4 multiple choice buttons. Click the button with the correct answer.
-Section 3 is a input field. Type in the correct answer and click OK or press Enter.

The thousands separator corresponding to the particular locale is used to present the number to be rounded. The separator may also be included in the input field without creating an error. This will help the player keep track of the number of zeros entered.

Version 2 — September 20, 2009 — 49 KB

Some minor updates were made based on some user feedback:
- moved the Play and Next buttons further from the edge. Sometimes the frame could be shown while trying to click a button.
- removed the focus from the multiple choice buttons as this could be confusing.

Added the user`s name to the output to add a little customization feel.
