The Rounding to the Nearest 100 printable is tailored for 3rd and 4th graders extending their estimation skills to larger numbers, building number sense and the ability to quickly approximate values in real-world contexts.

How to Solve Rounding

Focus on the tens digit to decide whether to round up or down to the nearest hundred. If the tens digit is 0 through 4, round down. If the tens digit is 5 through 9, round up to the next hundred. For example, 238 rounds down to 200, while 271 rounds up to 300. Keep the hundreds digit and replace the tens and ones with zeros.
