Rounding a number means approximating it to the nearest specified place value. In this lesson plan, students will learn how to round multi-digit whole numbers to the nearest tens, hundreds, thousands, ten-thousands, and hundred-thousands.
Rounding is an essential skill in everyday life as it helps us estimate quantities quickly and make approximate calculations. Learning how to round whole numbers allows students to simplify calculations and get close approximations when precise values are not necessary.
The quickest method for rounding whole numbers involves identifying the digit in the place value being rounded, looking at the digit to its right, and determining whether to round up or down based on that digit. This method saves time compared to replacing digits with zeros or checking the digit in the tens place.
Objective: Deepen students' understanding of number sense by using 10-frames, enabling them to recognize patterns, compare quantities, and represent numbers efficiently.
