Rounding Numbers With a Number Line
Many strategies exist to teach students to round large numbers, some of which are listed in the presentation. Here is a step-by-step guide on rounding numbers with a number line:
- Find the digit in the place value that the number will be rounded to.
- Identify the two benchmark numbers the number being rounded falls between. (For example, if 103,598 is being rounded to the nearest thousand, the two benchmark numbers will be 103,000 and 104,000.)
- Plot the benchmark numbers and the midpoint (in this case, 103,500) on a number line.
- Plot the number being rounded on the number line.
- Whichever benchmark number the number being rounded to is closer to is the answer. Numbers that land exactly in the middle are rounded up to the right.
Teaching rounding with a number line is a fantastic way to promote understanding and visualization as students learn this essential skill.
