Rounding Numbers to the Nearest Ten and Hundred

The video tutorial introduces the concept of rounding numbers, starting with rounding to the nearest ten using a special hundreds chart. It explains how to determine which multiple of ten a number is closer to, using examples like 27, 47, and 51. The tutorial then progresses to rounding larger numbers to the nearest hundred, explaining the process without a chart due to the large range of numbers. Examples such as 278, 26, and 87 are used to illustrate rounding to the nearest hundred. The video concludes with encouragement to practice rounding and provides links to resources for further practice.

What is the purpose of the special hundreds chart mentioned in the video?

• To assist in rounding numbers
