Rounding and Word Problem Strategies

This video tutorial covers rounding multi-digit whole numbers to any place. It begins with an introduction to the concept of rounding and provides a learning goal. The video outlines specific rules for rounding, such as underlining the digit to be rounded and circling the digit to the right. Several examples demonstrate rounding numbers to different places, including hundreds, thousands, and ten-thousands. The tutorial also explains how to identify key words in word problems that indicate rounding is needed, such as 'about' or 'estimate'. Finally, it provides practice problems and encourages students to apply the rounding rules to solve word problems.

What should you do first when rounding a number?

• Circle the number to the left

• Underline the digit you are rounding to

• Add one to the digit

• Convert all numbers to zeros

If the circled number is 5 or higher, what should you do?

• Add one to the underlined digit

• Subtract one from the underlined digit

What should you do if the circled number is 4 or lower?

• Leave the underlined digit unchanged

• Subtract one from the underlined digit

• Convert the circled number to zero

• Add one to the underlined digit

What should you do after underlining the digit you are rounding to?

• Add one to the digit

• Convert all numbers to zeros
