Estimating Differences: How to Subtract Using Rounding Strategies

Math with Mr. J

This instructional math video provides a comprehensive guide to estimating differences when subtracting whole numbers. The presenter, Mr. J, demonstrates two primary strategies: front-end estimation (rounding to the leading digit) and a more refined method using halfway points to achieve greater accuracy. Through four distinct examples ranging from two-digit numbers to four-digit numbers, students learn how to convert complex subtraction problems into manageable mental math equations.
