Rounding Off

This interactive Shockwave applet provides practice in rounding numbers. Each level presents 10 grids of numbers, each with a specific challenge. Users select the number in the grid that is rounded correctly. Level 1 includes rounding whole numbers and numbers of one decimal place to the nearest unit, 10 or 100. Level 2 involves rounding off numbers with up to six decimal places. Level 3 includes rounding to a number of significant digits for whole numbers and decimals. A Key Ideas window explains how to round.
